Does anyone know if the JD2010, 4 pod diesel, early 60's model is negative to ground or positive to ground. Is there a way to test this, i.e. on the generator?

Positive ground? UGH! in reply to Tom inMo., 06-14-2005 18:30:46

I was hoping it would be negative ground. This is an old tractor and has been through a revamp or two, by previous owners. Is there a way to test whether it is actually still positive ground? Is there an easy and cheap way to change it to negative ground?

I would guess if you put a battery in it and hit the starter the engine will either turn or it won"t. I doubt that someone would have put a negative ground starter in it.
Positive grounding is just as reliable and reputed to be better than negative grounding in regards to corrosion.

What are you gaining by converting to negative ground?
