Be sure to install a snubber on your alternator. That way you
avoid all the trash talk about switching batteries while the
engine is running

Hi GW, thanks for the reply,I am hoping to go down the battery combiner
road when I get to that stage of progress. Don't know where you are but I
am
UK based. boat is about 30 miles from home in Suffolk so it is a bit of an
expedition when I go to do any work on it. When I learn how to do it I
will
set up a web site and post some pictures of the project. many thanks to
all
the people who post technical info on here. I have learned a lot but still
pick up new tips from other peoples experience.
best wishes to all
Peter

Hi Harry! Nice new screen name. Shows your ass almost as good as
seeing you in person.
Harry ? whos Harry shows your ass almost as dumb as the frequent
,very frequent, wrong info you post here.


To the person that emailed me at my spam address I will copy your
email here and answer you here, that email address is used up 100
percent by spammers I emtied it yesterday in case Larry wanted to
yell at me in person so your mail got trough (along with 4 copies of
the latest microsoft security patches that they were so kind to send
me at that address

I bought a boat about 3 years ago, it had three batteries. I was told
that
they were all wired independently, ie one for starting, one for house
systems and one for the winch. after parting with the money (following
a
survey which reading it again having stripped the boat out told me
what was
already obvious but little detail of anything else). having discovered
that
the rot in the deckhouse was far more serious than I had anticipated,
I dug
down as far as the batteries. All three were different (1 traction
type, 1
similar size but deep cycle leasure type and a smaller type as found
in
small cars as a starting battery) and were connected in parallel using
all
black cable of different dimentions. the worst thing were the numerous
items
connected directly to the batteries with no switches or fuses. It
appeared
to be a fire waiting to happen. The wiring was a mixture of household
and
auto wire with no obvious colour coding. All wiring was removed for
storage
in the nearest skip. When I finally rewire everything will be
'pretinned'
marine cable with all cables numbered at both ends. Hopefully this
should
help to reduce the 'Murphy' factor
I was not vastly impressed by the wiring as you will probably guess

What I was referring to was to make sure that the alternator was wired
directly to a battery ( something they can't do when they ship the
engine with no battery, they just wire to the starter) just make sure
that the sense line to the regulator goes to the same battery. You
have a choice as to how to charge the other banks, I like the battery
combiner concept a lot but can't always use it .

NEVER, EVER MOVE THE BATTERY SWITCH WITH THE ENGINE RUNNING......

or bad things will happen..........

Switching ground in this manner is idiotic at least, negligent or
dangerous at most. STUPID comes to mind, also.

NEVER, EVER connect the alternator so that you can not turn off the
battery switch while the engine is running.

OR Bad things will happen


leaving a boat wired in this manner is idiotic at least, negligent or
dangerous at most. STUPID comes to mind, also.

But STUPID comes to mind anytime I think of Larry w4csc so it makes no
difference anyway to you Larry.

What should you do if you get a engine fire be afraid to turn off the
switch, Hell Larry you never heard of Murphy?? I see a few boats
every year that got the switch off and the battery disconnected from
the alternator. When I am finished the alternator output is wired up
the right way and you can put that switch anyplace you want to without
causing any damage any other way is hmm is idiotic at least,
negligent or
dangerous at most. STUPID comes to mind, also

So you just keep on being stupid and I will keep wiring boats to try
to minamize the Murphy effect.
