I am preparing to rewire the console on this 87 GW Seafarer. Next to the 4 toggle switch panel is a single toggle switch that I have no idea what it controls. Does anyone have an idea? Thanks.
Looks like a kill switch. Flick it down and you probably won't be able to start the engine. If it's still operational, that is. At 40 years old and who knows-how-many-owners, you never know!
Agree with others, but the real question is what is it currently hooked up to, if anything? For that, you'll need to trace the wires. In 40 years, a lot can happen, it could be bypassed, hooked up correctly, or switching something else entirely.
