Golver 1 , pictures seem to show a lot of bad ground (corrosion) problems. Start with battery and clean all connections to ign switch. Where coils mount to block and solenoids mount must all have good grounds. wires connecters can be corrodided under heat shrink. Use only marine grade wire and connectors as they are tinned (all strands of wire are soldered and then coated) using automotive wire and connecters is a slow corrosive death in a marine environment. You can check starter neg. jumper battery cable to starter housing, pos. jumper battery cable to + stud on starter. your set up is like pre 73 ford trks that are mounted on fender. You can check grounds by hooking test light to positive post of battery and point (light) end to mounting brackets of of relays and coils. Crusher
