YM1500 red is electrical system - or + ground

[Normmm]

I have a 1500 red that I am to sell for a friend who was transfered to Alaska suddenly and did not have time to sell the tractor. There is no battery in it and I can find no markings. Do all Yanmar tractors use the same polarity.
After I check it out I will post a for sell on it.

If it is original, as you SIT on it, the positive cable is on the left side. You should be able to follow the right cable to where it grounds on the frame to be certain.

Thanks! Looks like I am not the only one who has his morning coffee with the Yanmar group.
