Wondering if someone more skilled can help me understand/troubleshoot. Boat has been randomly shutting down. The is the key version so it does not have the main battery switch. When the boat shuts down, the ignition switch trips under the drivers feet. Also, it seems like the circuit breaker in the bow trips ( I believe this one trips first, then when reset the ignition trips, but not 100% sure if that's the same everytime). The circuit breaker in the bow had some loose wires and was getting hot, so those were tightened. We tightened the wires on the circuit breaker box too.
I am not sure if this is a weird coincidence, but the volt meter in the dash (gauge) has only been showing 10 - 11 volts. Not sure when that started. When tested the batt and alternator, both are working properly. Bad gauge or something is causing the wrong reading that is tripping the breakers? Any help is appreciated.
