Stop in for a cup of coffee

So had a service call today. Local marina having trouble figuring out wiring for lights and horn. On a pontoon boat.
They keep aggrivating the angry pixies and releasing the magic smoke. 2 days.
Turns out the mechanic is a dumbass. B+ to one switch terminal and other termnal to B-
Makes me wanna shake my head.
20 minutes and it was fixed. I am a God!!
