I've had it happen to me. Once, the port engine started spontaneously and was idling happily at the dock until discovered by a dock neighbor. It turned out to be a shorted ignition switch due to a leaking rubber boot in the tower. Then a month later, I arrived at the boat to find the starboard engine alarm sounding. You guessed it, another shorted switch, although the boot looked fine. I should have replaced both of them the first time.

Beware the previous owner, boat yard "electricians", professional qualified electricians and home brewed electrical work...

Nobody can be trusted.

Wires attached here, there and everywhere...

I've seen an 8V71 diesel started via a poorly placed little 16 gauge wire. Complicated Command Vehicle situation, multiple battery banks, multiple circuits, a pair of generators, split shore power... and one little wire incorrectly run between the two sides... Pull the battery switch, push the start button and vroom!

Start tracing.

EVERY wire needs to be assuredly connected, and protected, where it should be.

I am still tracing wires to figure out what is the purpose of each one of them in the spider net I have aboard. And I am still finding some jewels in the connections, the last one being the negative wire from the alternator, around 2 feet long... and made of 3 short pieces of wire twisted one after the other with some tape: pure engineering!
