The Ultimate Alternator Project
 
Those of you who followed along with the updates from our Caribbean
cruise earlier this year, may remember that we experienced some
alternator issues along the way. This was disappointing for a number
of reasons because we had already spent a fair amount of time, effort
and boat bucks trying to find a high output alternator that was also
durable.

Our goal is to not run the generator at all when under way, and to
minimize generator time when anchored. The potential savings on
generator fuel and maintenance add up to a big number. To that end
we've installed a 2,000 watt inverter and a bank of 8 golf cart
batteries with a total capacity of about 1,000 amp-hours.

The inverter and battery bank work well together but the batteries
eventually need to be recharged, and when underway, the alternator
needs to supply inverter amps, recharge amps and onboard house loads
like navigation equipment, lights, auto pilot, engine room blowers,
etc. Peak alternator loads can easily approach 250 amps and average
well over half of that.

To make a long story short, no automotive alternator that we've tried
has been capable of these loads over a long period of time, even those
that have been beefed up with heavy duty components. We burned out a
total of 4 over the course of 6 months in the islands. Repair and
replacement was problematic to say the least.

After consulting with Tim, our cheerful, ever helpful, resident
alternator expert on "rec.boats", and a number of other sources, I
decided that a fresh approach was needed. Enter a company called
Leece-Neville, a division of Prestolite, that has been making heavy
duty alternators for a long time. LNs are used all over the world on
fire trucks, ambulances, busses, big trucks, heavy duty construction
machinery, etc. Their big alternators make everything else look like
a toy, weigh over 35 pounds and are priced accordingly. Many of the
really big ones are north of $2K at full retail. Thanks to the
internet and EBAY however, they are now becoming available at more
reasonable prices. I was recently able to buy a unit that had been
remanufactured to like new condition for about $400, a bargain
compared to some of our previous repair/replace experiences. It is
rated at 270 amps continuously at high temperatures, and is designed
for fire trucks, ambulances and busses.

There are some downside issues however: It is designed for a so
called J180 mounting bracket; requires multiple drive belts since it
can use as much as 6 or 7 horsepower; and is not ignition protected
for gasoline engines.

Ignition protection is not an issue for our diesels, and fortunately
the front pulley on a Detroit 6-71 can accomodate up to three belts.
The mounting bracket was problematic however since the existing mount
was for a Delco 2 inch foot. In exchange for a sizable boat buck
fraction, a local machine shop fabricated a custom made J180 bracket
from 1/2 inch cold rolled steel. In combination with some Grade 8
steel mounting hardware and a new adjusting arm, everything is now
solidly attached, lined up and looking good with 3 brand new Gates
Green Stripe belts installed. In testing it has put out well over 200
amps while maintaining reasonable temperatures.

Stay tuned for the long term durability reports... :-)

Wayne,
I think you are on the right track but those kind of currents indicate your ship voltage should be 24 volts not 12. I really like
your golf battery solution. I hope your inverter is sinusoidal and not square wave, as the latter will play havoc with most
electronics not to mention its RF generation. Just as a note, some of the popular computer UPS systems use 24V internal batteries.
They are easy to modify for external power and they produce a clean sinusoidal output.

Yes, the inverter is sine wave output, and we have a smaller one for
backup. I previously installled a modified sine wave inverter on our
old boat and we had a number of issues with it. There's no longer a
reason to go non-sine wave in my opinion since prices keep dropping on
the electronics.

I also agree that 24 volts would be desirable but that would have
required a lot of modifications or setting up some sort of dual
voltage system since everything on the boat is set up for 12 volts.
It is much simpler having everything at one voltage even if not
entirely optimal. I even considered a 48 volt inverter at one point
with a totally isolated house bank to feed it.

As it is the golf cart batts are less than 4 feet from the inverter
and alternator, and everything is interconnected with 2/0 and 4/0
cables which minimizes IR losses.

Yes. I installed a Balmar high output alternator on one of my old
sail boats. That boat had an Atomic 4 gasoline engine and needed to
have ignition protection which Balmar offered. I believe the 4000
series Leece-Nevilles are a better unit and I can buy 4 or 5 of them
for the price of one Balmar.

It looks like the right piece of equipment for the job----however,
I find the washer stack and bolt on the belt-tensioning arm a
bit troublesome. There's an inch or so of lever arm and it looks
like about half an inch of thread into the alternator front plate.
If that front plate is cast aluminum, how long will it be before
that bolt loosens with thermal cycling and vibration?

For a few more boat bucks, you could replace the washer stack with
steel block of the appropriate thickness---perhaps with some filed
'tooth' on each side. Spend a few more bucks and get a bolt
a half inch longer. You might also have clearance for a thin nut
on the front to act as a lock nut.


When you're cranking out 200 amps, there's going to be substantial
load on that bracket.

TINS: Back in the 70's I drove a Chevy Vega with an aluminum
block. That never gave me problems, but I did have an alternator
problem. I was careful with belt tension and kept that bolt tight.
However, the belt kept getting looser. I finally disassembled the
system and found that the bottom of the alternator was pivoted
on a 4" long steel pin through the alternator housing. The housing
had worn away so that the 3/8" hole through the housing was now a
slot about 3/8" wide and over 1/2" long. At the belt end, you could
see the pin coming out of the side of the alternator housing.
I replace the alternator and the new one lasted until the car
was totaled by a teenager who ran a stop sign and crunched my
passenger side quarter panel.

Good eye, was wondering if anyone would comment on that.

It's not just a washer stack however. At this point it is more of a
custom spacer since the SS washers are firmly stuck to each other with
JB weld.

I understand your point regarding long term stress on the adjusment
tab and bolt. It would certainly be easy enough to get a longer bolt
and put another washer/lock washer/lock nut combo on the other side of
the tab. Good idea.

I had a similar issue with the alternator mount on our generator (40
hp Yanmar diesel), after about 3,000 hours. The mounting hole went
egg shaped and was virtually impossible to replace since it was part
of a casting on the front of the engine block. My local alternator
shop came up with some SS circular shim stock just the right size for
the mounting bolt. I cleaned up everything with acetone and bedded
the shim stock into the mounting bracket with JB Weld. It has been
working fine now for over 600 hours of run time.

Nice pix.

I'd be worried, however, about all the washers for depth. Not possible to
build in a bend to the tightening arm to bring it flush to the alternator?

Yes. I installed a Balmar high output alternator on one of my old
sail boats. That boat had an Atomic 4 gasoline engine and needed to
have ignition protection which Balmar offered. I believe the 4000
series Leece-Nevilles are a better unit and I can buy 4 or 5 of them
for the price of one Balmar.


You have to know how to buy them. Not through the factory at retail,
that's for sure.

Not sure if he's still doing it but the owner used to bring all his
returns, remanufactured to the annual sidewalk parts swap at Fisheries
Supply. Prices were half or less and for every applications. Balmar
units look great with the white finish and for us, made a significant
dent in our genset hours.

So, forget the huge battery bank and get one of these instead. (Save your

Those of you who followed along with the updates from our Caribbean
cruise earlier this year, may remember that we experienced some
alternator issues along the way. This was disappointing for a number
of reasons because we had already spent a fair amount of time, effort
and boat bucks trying to find a high output alternator that was also
durable.

Our goal is to not run the generator at all when under way, and to
minimize generator time when anchored. The potential savings on
generator fuel and maintenance add up to a big number. To that end
we've installed a 2,000 watt inverter and a bank of 8 golf cart
batteries with a total capacity of about 1,000 amp-hours.

The inverter and battery bank work well together but the batteries
eventually need to be recharged, and when underway, the alternator
needs to supply inverter amps, recharge amps and onboard house loads
like navigation equipment, lights, auto pilot, engine room blowers,
etc. Peak alternator loads can easily approach 250 amps and average
well over half of that.

To make a long story short, no automotive alternator that we've tried
has been capable of these loads over a long period of time, even those
that have been beefed up with heavy duty components. We burned out a
total of 4 over the course of 6 months in the islands. Repair and
replacement was problematic to say the least.

After consulting with Tim, our cheerful, ever helpful, resident
alternator expert on "rec.boats", and a number of other sources, I
decided that a fresh approach was needed. Enter a company called
Leece-Neville, a division of Prestolite, that has been making heavy
duty alternators for a long time. LNs are used all over the world on
fire trucks, ambulances, busses, big trucks, heavy duty construction
machinery, etc. Their big alternators make everything else look like
a toy, weigh over 35 pounds and are priced accordingly. Many of the
really big ones are north of $2K at full retail. Thanks to the
internet and EBAY however, they are now becoming available at more
reasonable prices. I was recently able to buy a unit that had been
remanufactured to like new condition for about $400, a bargain
compared to some of our previous repair/replace experiences. It is
rated at 270 amps continuously at high temperatures, and is designed
for fire trucks, ambulances and busses.

http://www.prestolite.com/pgs_products/specs.php?item_detail_id=951&item=A0014867JB&produ ct=ALTERNATOR

There are some downside issues however: It is designed for a so
called J180 mounting bracket; requires multiple drive belts since it
can use as much as 6 or 7 horsepower; and is not ignition protected
for gasoline engines.

Ignition protection is not an issue for our diesels, and fortunately
the front pulley on a Detroit 6-71 can accomodate up to three belts.
The mounting bracket was problematic however since the existing mount
was for a Delco 2 inch foot. In exchange for a sizable boat buck
fraction, a local machine shop fabricated a custom made J180 bracket
from 1/2 inch cold rolled steel. In combination with some Grade 8
steel mounting hardware and a new adjusting arm, everything is now
solidly attached, lined up and looking good with 3 brand new Gates
Green Stripe belts installed. In testing it has put out well over 200
amps while maintaining reasonable temperatures.

Stay tuned for the long term durability reports... :-)

New alternator and bracket prior to installation with a beverage can
for size reference:

http://img140.imageshack.us/img140/3557/preinstallwithnewbracke.jpg

After installation, with new HD belts and adjusting arm. The black
detritus in the background is left over from the many previous
alternators and belts which gave up their lives in that spot:

http://img16.imageshack.us/img16/1462/installedimg0573.jpg



It looks like the right piece of equipment for the job----however,
I find the washer stack and bolt on the belt-tensioning arm a
bit troublesome. There's an inch or so of lever arm and it looks
like about half an inch of thread into the alternator front plate.
If that front plate is cast aluminum, how long will it be before
that bolt loosens with thermal cycling and vibration?

For a few more boat bucks, you could replace the washer stack with
steel block of the appropriate thickness---perhaps with some filed
'tooth' on each side. Spend a few more bucks and get a bolt
a half inch longer. You might also have clearance for a thin nut
on the front to act as a lock nut.


When you're cranking out 200 amps, there's going to be substantial
load on that bracket.

TINS: Back in the 70's I drove a Chevy Vega with an aluminum
block. That never gave me problems, but I did have an alternator
problem. I was careful with belt tension and kept that bolt tight.
However, the belt kept getting looser. I finally disassembled the
system and found that the bottom of the alternator was pivoted
on a 4" long steel pin through the alternator housing. The housing
had worn away so that the 3/8" hole through the housing was now a
slot about 3/8" wide and over 1/2" long. At the belt end, you could
see the pin coming out of the side of the alternator housing.
I replace the alternator and the new one lasted until the car
was totaled by a teenager who ran a stop sign and crunched my
passenger side quarter panel.

Boat, with new alternator well hidden, docked last weekend on the
Caloosahatchie River in southwestern Florida:

I thought the same thing about the washers.
I wonder if there is enough clearance to put a couple of bends in the
tension adjuster arm to eliminate most or all of the spacer washers. If
necessary, a stiffener bar could be welded to the back of the arm.

You'd have to duct it and exhaust it to the outside via cowlings and forced

Yes. That's one of the good things about being self-insured. Ridiculous,

anticipated and eliminated. Safe boating is no accident. Insurance very
often CAUSES accidents. How many times have you heard some insured idiot say
something like, "I don't really care about that; that's why I have
insurance," and off he goes engaging in the same, old, dangerous routine.

"Insurance is socialism." I've not heard that before in regard to

If not, it is I who would rather not be anywhere near you or your insured

hazard to navigation. It is better to avoid a collision than to have the
means to pay for some of the damage to property, life and limb after years
of extended after the fact litigation Get a clue. Who wins? Lawyers and

We have no problem figuring out where to put the 200 amps when

The inverter pulls down about 80 to 100 amps powering the fridge,
freezers and nav computers.

Recharging the inverter batts from the previous night can use 20 to
100 amps.

House loads from nav gear, auto pilot, lights, radios, radar, engine

Get back to me in a couple of years.

Your boat's electrical system is not the same as a transit bus;
however, you are applying bus design requirements to your boat.

Bottom line:

You simply can't have too big a house bank on a boat.

A fact of battery life often forgotten is that for every 100AH taken
out of a battery, you must replace it with 125AH.

The maintained recharge rate of a house bank is 15%.

IOW, the max sustained recharge rate for 1,000 AH bank is about 150A.

You can take all the games regulator people try to promote and put
them where the moon doesn't shine.

When it comes to wet cell batteries, there is no free lunch.

Have fun.

I do, too..... and I wouldn't dare own or operate a boat without

I can only assume a few things:

One, you don't own a boat large enough to be kept in dry or wet
storage. If you did, you'd be required by the marina to carry
insurance...or

Second, you have no assets and no real concern of liability.... can't

If I have the right guy... he owns a 27' mustard yellow Coronado

backwater in Florida.
He has no fears because no one would bother to sue him for that boat

Nice job improving the group, dummy!

Hello:

*To that end
we've installed a 2,000 watt inverter and a bank of 8 golf cart
batteries with a total capacity of about 1,000 amp-hours.


* Peak alternator loads can easily approach 250 amps and average
well over half of that.


There are some downside issues however: *


and fortunately
the front pulley on a Detroit 6-71 can accomodate up to three belts.
In testing it has put out well over 200
amps while maintaining reasonable temperatures. *


Stay tuned for the long term durability reports... * * :-)


Most older homes had a 100 amp load center. For the last 30 years a
200 load center (braker panel) is the residential standard. I rewired
my home 10 years ago and the union journyman electrition installed a
200 amp panel. The home was 2600 sq ft..

With the greatest respect. Why would you need MORE amps than the
common 2600 sq ft home ?

Id think at that point it would make more since to install a dedicated
hard wired diesel powered generator.

When you start taking parts of a 71 series Detroit Id think you would
have realized your trying to get an elephant to ballance on a
football.
Yours truely,
Bob

You're going in the wrong direction. Using a huge battery bank kept charged
by a heavy-duty alternator is still going to be inadequate for spoiled motor
cruisers who really want a house with all the comforts of home that floats
and goes from place to place.

So, forget the huge battery bank and get one of these instead. (Save your
auxiliary engines for moving the floating home from place to place.)

These tripacs are the cat's meow. They provide heat, air conditioning,
battery charging all in one compact package. You see more and more of them
on over-the-road tractor/trailers.

"The TriPac APU provides
? cab heating and air conditioning
? truck engine block heating
? truck battery charging
? 12Von-board power
? optional 120V household electrical power

"The system is powered by a diesel engine, running an automotive style 12V
alternator and belt driven air conditioning compressor. The APU HVAC system
is independent of the truck system. Cab heat is provided by a fuel-fired
heater, and engine block heat is provided by exchanging coolant between the
APU engine and the truck engine."


I hope this helps.

Are they approved for marine use? Can you operate them in an enclosed
engine room or do you have to hang it off the gunwale?


You'd have to duct it and exhaust it to the outside via cowlings and
forced
air but it would provide the electricity to do that, no problem. As for
some
government, marine use approval, who cares? It's high time the
government
took a hike out of our everyday personal lives with their red tape. A
commercial boat is one thing, a private yacht is another thing
entirely.
Your insurance company cares.



I don't do insurance. Never have, never will. Insurance is a giant
rip-off.
Just go downtown in most any big city and some of the biggest, most
expensive buildings will be banks and insurance companies. That should
give
you a clue as the giant swindle that is called insurance. If you wish to
swell their coffers so be it but I will not.

Are you "self-insured" for liability, too?




Yes. That's one of the good things about being self-insured. Ridiculous,
million-dollar lawsuits for stubbed toes and the like are not worth filing
so they are not forthcoming. Other, more serious things can be and should be
anticipated and eliminated. Safe boating is no accident. Insurance very
often CAUSES accidents. How many times have you heard some insured idiot say
something like, "I don't really care about that; that's why I have
insurance," and off he goes engaging in the same, old, dangerous routine.
Insurance is socialism and socialism doesn't work.


Wilbur Hubbard.





Ok, what have you done with the real Wilbur?
