I have a 1977 Bertram 28’ convertible with twin Mercruisers chevy 350’s. I was having a reoccurring problem getting my port starter to activate consistently. After chasing the solenoid power wire down I found it goes to another solenoid at the rear end of the engine. I assume it is the original remote solenoid that is not necessary with my current starter. I bypassed the solenoid on my engine and the starter works every time now. Are you familiar with this setup and is my assumption correct? Also I see a circuit overload reset button next to the solenoid and I’m not sure what it is used for (it’s not on my electrical schematic).
