I recently picked up a Yamaha Sun Classic cart. I had never seen or even heard about these before but here it is.
There's a plate under the front with "J50-100999" stamped on it. A small amount of research tells me this is a 1991 G5 ?
Sometimes when I went to start it, the engine wouldn't spin over as if the battery was disconnected or something. I discovered that the voltage regulator sends 12 volts to the starter solenoid when starting. Sometimes it does not. I was going to buy a new voltage regulator but I came up with a work around.
I jumped the 2 terminals that are part of this circuit and I installed a momentary button below the shifter. So far so good. Anyone here ever heard of doing this?
This cart didn't have a top when I got it and apparently they are impossible to find. I did however have an EZ-GO top so I flipped it around backwards and bolted it up there. It works.
