It's a Hyundai golf cart with the Suzuki V270G 8.5 engine in it. I also know they were only made a few years in the early 90's and no real changes were made to them during that time so the model year of it doesn't really matter. It's also pretty rare (though not the collectable kind of rare) so finding info is difficult and I hear parts are virtually unavailable.
I'm scouring parts diagrams but I'm lost. Not knowing how it's supposed to work and having a big suspicion that the wiring that's on it is incorrect is making it very hard to figure out how it should be wired.
Things like having the key switch with 4 terminals on it but I find with a volt meter that the only thing it does is connect and disconnect two of them. It only has two positions Off and On. It doesn't have a start position. The only thing I see it's doing is connecting power to the backup alarm switch and to the solenoid. That accounts for 2 terminals on the switch. A 3rd terminal has a wire that goes to battery ground but this terminal never makes connection with any other terminals or the key itself which is the only metal part of the switch. The 4th terminal has no wire on it and is never connected to any of the other terminals on the switch or the key itself.
Get this: That very same terminal on the solenoid that the power is fed to from the key switch has another wire attached to it. That wire is spliced into 3 times so it actually connects that solenoid terminal with, the regulator, the coil, the generator (one of the small wires coming out of it) and a small box that I can't identify. The small box is plastic and like 1 X 1 X .5 inches with several wires coming out of it. It looks like a regulator used on a riding mower but this cart has a regulator that looks like a regulator used with an old starter/generator already. So I don't know what the small box is.
There are no switches at either brake or gas peddle or along the cables and connections from them that would work to start the engine or turn it off things the key doesn't seem to do. Like I said I'm lost.
