My G763 seat switch wasn't working, so I bought a new one and installed it. The unit worked "OK" for about a 15 minutes and I lost it again. So I checked the wiring, cleaned and scraped and sanded all grounds even the ones in the engine compartment. Still no help. I took the seat switch completely out of the seat bar and I could get it to make. unplugged it and plugged it back and it kept making. I let it set about 3 hours went back and it wouldn't make again, then I happened to get a wrench close to it without touching it and it made again. Can anyone explain how it works or give any advice on this subject. I don't understand if the magnet is a transmitter and something else is the receiver or if somehow it creates a small amount of voltage or what. Sometimes if you hit traction lock override the seat switch will come on. Just don't know everything I should about the machine.
