i reversed the batt terminals on Force 50, now what?

[smithsmarina@gmail.com]

Engine: Force 50<br />Year: 1987<br />Model: 507X7C<br />Serial: 1251<br /><br />Yes i know its stupid, what damage have i done? Im going out with the seloc manual and an ohm meter to start testing things. I wanted to see if there is an order i should check, im sure people do this all the time (and hate themselves for it), and to see if there was anything else i should know.<br /><br />1.) it was reversed for 5 seconds, and there was sparking at the terminals<br />2.) the choke was applied and the key was turned<br />3.) after ward there is no response from anything electical from the boat or motor (electric choke, starter, running lights, radio)<br />4.) the fuse on the battery wire is not burnt<br />5.) the starter works if directly run off jumper cable<br /><br />need to figure out what i toasted (please dont say the stator) ~gratis<br /><br />Chris @ Smith's Marina

Circuit breaker probably tripped however the regulator/rectifier is probably toast. If you can start it hook a battery meter up to the battery and see if the voltage goes up to above 13 volts. If not you will need a new rectifier.

yea the circut breaker tripped. When i reset it everything seemed to work (choke and starter operation by the key. I read the rectifiers are very sensitive anybody know how to test them? People at my marina are saying an ohm meter. I read an old thread about a 4 post rectifier on a 70' something chrysler engine. Could they be the same?<br /><br />~gratis

With the engine running, check the voltage at the battery.<br />It should be substancially higher when the motor is running.<br />As eurolarva said, 13volts or higher would indicate the charging circuit is working.
