Stumped???

The real problem here is the fact it went swimming! Be an ATV or automobile or any other motor driven vehicle, once they drown they will have continuous electrical problems. Look at all the vehicles from the hurricane and floods, nobody wants them as they will have electrical issues down the road... With that said your best hope is a complete replacement of all electrical switches and connections, once water invades these then all kinds of issues develop over time, and have a habit of continuing. Ask any insurance adjuster about a flood vehicle and they will tell you to part it out or junk it.
