boat batteries
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.

| 1 Set battery selector switch to both
2 Clip test leads to battery. (Observe proper polarity) If lights light up
go to step 3
3 Move red lead to lug on starter solenoid that connects to the wire that
goes to the battery selector switch. If lights light up try tilt and trim.
Try to crank over engine with key (just for 1/2 second. don't let engine
start).
4 report your findings. |

| 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? |

| 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? |

| 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.

No wing nuts have hex nuts |

| Mark,
Hello, sounds like you have a simple problem, but you need to work
through the electrical system from the battery forward to the engine's
electrical system. Call me at my shop and I'll walk you through it.
Call me at 601-366-4999 (Mon - Fri 8am - 5pm CDT) I would be glad to
help.

| 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. RCE |

| 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. RCE |

| 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 |

| 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

power, starting at the battery and working forward. |

| 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?
