Hello, my name is***** will assist you.

Throwing the breaker on the engine is an indication of the charging system delivering too many amps the the battery, or the battery is in a overcharged state. Check the running volts on the engine going to the breaker if it is over 14V DC, the regulator on the engine would be bad.

I know battery is not overcharged.. I will be at my boat on Tuesday and try bypassing alternator to see if generator engine runs. Will get back to you.
