I have a 2001 2855 Bayliner with a 7.4 L MPI with Bravo III. i was taking her out for the first journey of the season and the sun was going down. i had all my nav lights on and instrumentation. i have owned this boat for 4 years without electrical issues. all of a sudden i hear a pop and all my 12 v lights went out. the engine remained running and was able to get back to the dock. back at the dock i tried resetting the main fuse that is located at the battery switch. the main fuse breaker will not reset. checked the main fuse on the engine, it did not pop and was fine. electrically i am lost, i do have an electrical schematic for the boat. i do own an ohmeter. i checked my battery connections are fine, i have a onboard battery charging system that seems to be working fine. i have power to dash gauges but all instrumentaiton that works on the switches on the helm are not working.

If the main fuse breaker will not reset I would be suspect that the breaker may be bad.

A breaker will trip typically when there's a fault. Be diligent going over your electrical, you may have a real fault. Try another breaker to rule it out but be prepared in case it trips too.

Try disconnecting the output wire to see if the breaker will set. You can try another breaker as well but if that trips you need to start isolating the load until you discover what is causing the trip."3 wide" post=579570 wrote:

After 4 years, a wire could be chafed, loose, broken breaker, or a ground issue. THE KEY: Only check one thing at a time or you won't be sure you found it.
