Or something else? Vanguard engine with a sea dog type kill switch. It has the 4 prongs (I believe it says I and V) on them. It has stopped working. The two wires running from the kill switch are pretty dadgum corroded looking but everything is connected like it should be. Also, the several wires running from the ignition are corroded to. I am replacing the wires and connectors. Should this fix my issue? Kill switch is pretty new and doesn’t look like anything is wrong. It still plunges in and out fine.
