boat is quite new. all wires are clean with no corrosion. It worked
with the old batteries right up until it died. when i replaced new
batteries nothing works. I either blew something or i have the wrong
batteries. power tilt is the only think that works.

It's not your batteries. Keep plugging away. You're going to find the
problem and feel pretty good about your new found knowledge of how your boat
works.

Mark - you got me.
I have a hard time believing it is the wrong batteries. since the power
trim works that would seem to imply that the ground is good. I just
can't imagine why the lights would be dead also.

Mark,
The information you have given us so far is not enough to even begin to
troubleshoot your problem.
Please supply the make and model and year of the engine and boat so that we
can try to visualize what you are looking at. What worked with the old
batteries? What died? Were the old batteries worn down? If they were worn
down, could it be from leaving an accessory on when you left the boat, or
from months of non use? Did you check to see if the old batteries needed
water? Did you try to recharge the batteries? Did you have the batteries
tested? (Not at Sears, I hope). How old are the old batteries? Is all the
wiring to the batteries color coded? i.e. red for positive and black for
negative. Have you looked carefully for any loose wires that may not have
been reconnected to the new batteries? Where is the selector switch
physically mounted? When you are in the cockpit facing the engine, describe
where the batteries are located.

We have determined so far that the sterndrive will lift to the full up
position. It takes significant power to accomplish that task. The batteries
are OK. The next logical step to take is to follow the battery cables to see
where they go. The blacks need to go from the negative on the battery
directly to the engine block. The two red cables go from batteries to the
selector switch. The third red cable on the selector switch goes to the
starter solenoid. You may find other smaller wires connected to the
batteries. Those would be for builder installed accessories; and have
nothing to do with engine function.

I just put in two car batteries 12v in my boat and nothing happens. I
put the wires on the wrong terminals for an instant and then corrected
my mistake. Nothing happens. I checked all my fuses and nothing
blown. I was told to use interstate # SRM27XHD batteries. I couldn't
find them so I used sears. What did I do wrong.

When you say "nothing happens" .... can you be a little more specific?

One of the most common "forgets" with an outboard (assuming you are talking
outboard here) is forgetting to install the safety clip on the kill switch.
I do it all the time. Forget that and nothing will happen.

On a io the engine will crank, it just will not fire with the safety
clip disengaged. But cranking is somthing just not running..

Now that I think about it, it's the same with an outboard too. It'll crank,
but not start.
It's been awhile since I used my outboard.

Thanks for the correction. I feel for the OP. Hoping he didn't fry
something when he hooked the batteries up backwards. My son did that to his
first car - an '87 Merc. Messed it up pretty bad.

I hear ya, I would think one of the service guys would know what to
check since it was hooked up incorrectly.

From one of his other post it sound like the power trim works, so he is
getting power in the system. I would think he should be able to get
power to the lights and other things. But so far from what I can tell
that is not the case.

A common problem is forgetting to hook up the motor's black ground cable.
Usually just the cable between the negative terminals is installed. One
battery should have twin heavy battery cables on the negative, one for the
motor and one for the 2nd battery.

Bill Grannis
service manager

from what I can see the black ground cable was already attached to the
terminal wire. So all I should have to do is connect it to the new
batteries. If the diods in the alternator are fryed will that cause
this problem?

In an instant, you can fry the diodes in the alternator with reversed
battery leads. Hopefully the ground going to the back of the engine slipped
down in the bilge out of site. Was anything working before you changed
batteries?

if the diodes are fryed how hard is it to replace them or do I need a
new alternator. Can I test the power going in and out of the
alternator to know for sure it is fryed?
