New to me JD750. Bought over summer and used a couple of times to mow.
Tractor had been sitting in garage for a couple of months since last use. I've been trying to get it ready for winter, starting with lights (none worked when I bought it). Now have panel indicator lights, tail lamp and rear flood, but no headlights or warning lamps (more on this in a later post).
When I got done playing with lights, I decided to start the tractor. Tractor would not start. Had been starting on first or second try up to this point. Checked all fluids. All appear ok. Weather has gotten colder, barely freezing on a few nights, but 50-60's during day. Added anti-gel to fule tank (I know, if it's gelled in lines, too late now, but better than none). Decided battery was too weak to turn starter (starting circuit buzzed, but starter did not crank on key, battery voltage 11.4V).
When I decided to try to boost, got a surprise; battery appeared to be in reverse orientation (neg (-) post of battery connected to red pos (+) terminal lead, pos (+) post of battery connected to black neg terminal lead)?!
I looked through owner's manual and service manual, but could find no apparent reason to switch battery leads...
Bought tractor from reseller, who bought it at auction in upstate NY. Little history on past owner.
Bought a replacement group 24 850CCA battery at Wal-Mart, but have yet to connect it.
Some questions following this "discovery";
1. Is it possible that previous owner decided to switch terminals to reverse the ground from (-) ground to (+) ground? For what reason?
2. If so, is it possible that additional modifications were performed for electrical system to operate on (+) ground, and that I might do damage by connecting new battery in "correct" position / (-) ground?
3. What damage can arise from connecting battery in reverse, as done above?
4. Is it possible that remaining nonfunctional lights are from connecting battery in reverse orientation?
Thanks, Eric.
