Stop in for a cup of coffee

I went on a service call to look at a wiring issue on a pontoon boat at a marina. Owner’s “ mechanic” rewired a customer’s boat. I’m suprised that dipshit can tie his own shoes.
Wired b+ to one side of switch,and b- to other side. Then series off switch terminals to the accessories, lights, horn,livewell pump...

there was fricking smoked wires everywhere. No worries, business owner is an idiot too.
I cant believe people actually brought their stuff there to get fixed.
That place kind of sounds like the place where my parents took our 460 powered jet boat and wouldn't you know it, the poor thing had asthma after they "fixed" it.
they put a little *650cfm carburetor on it. Took it to another reputable shop and they actually fixed it with a 850 double pumper.
