I was hoping for some help as I have exhausted all the ideas I could think of for a fix. I am moderately mechanically inclined but am stumped by this.
Symptoms:
Turn on ignition key and ignition switch in cabin panel and then try to start with rocker switch at the helm and get no sign of electrical current... no beep, no Fuel valve switch turn on noise, no crank. Starboard side only as the Port side cranks as normal. Oddly, if I hold down the bridge/crossover rocker between the port and starboard start rockers, the starboard side beeps, fuel switch turns on and it cranks. If you let go of the bridge/crossover rocker switch it is dead again. This is repeatable.
Tests and fixes tried so far:
Fully charged and tested starboard battery bank. Replaced slave solenoid on top of the engine. Checked the red button circuit breaker on top of the engine, it is not tripped. All breakers on the engine room DC breaker panel are untripped. Replaced both the starboard and port battery relays/solenoids inside the DC breaker panel. Replaced the starboard starting rocker switch at the helm. Tested by jumping the slave solenoid to "jump start or jump crank" the starboard engine and no crank, nothing.
I am at stumped! Not sure how to proceed from here. I assume since the starboard engine cranks when using the bridge/crossover switch at the helm that the engine, starter, fuel switch are all fine. I also assume that since I cannot affect a "jump crank" across the slave solenoid that the ignitions switches in the cabin cannot be the problem since they are not needed to jump crank it anyway. :huh:
Any help to find my electrical gremlin would be greatly appreciated!! Thanks so much
