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.

Disconnect the batteries until you find the problem.

Now I assume you have a Mercruiser or one of the clones thereof. Somewhere
on the rear top of the engine there should be a big red circuit breaker -
looks like a big red button if I recall. Push it in, hook your batteries
back up and see what happens.

I did that with the batteries hooked up. I will diconnect the
batteries and push the red breaker then connect the batteries back up.
I'll let you know. Thanks

I disconnected the batteries and pushed in the red circuit breaker and
then reinstalled the batteries. Still nothing. What about the
alternator diods?

Don't know, but listen to JIMinFL. He knows these systems well.

The reason I suggested that you disconnect the batteries is that if
somewhere you have a short, something may get hot in time. I wouldn't leave
them connected if you are not there troubleshooting.

RCE

Don't worry about the alternator just yet. Do you have any test equipment?
Are all your battery connections clean and tight? If you are using wing nuts
on the battery posts, throw them away and install hex nuts instead.

After verifying that the batteries have a charge, I would check the
ground and bypass the switch. You should be seeing power somewhere
unless there is major corrosion a broken cable I would think. Even if it
does not start.

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.
