Dave: Just before I moved to Ontario from Nova Scotia, my 130 had a batery that would loose charge after a few days. The battery had a few years on it so I decided to replace it just so hauler wouldn't have problems. Well, he drove 1,300 miles with switch on. It fried the battery, wiring harness, alternator, amp gauge and of course points. I agree battery probably should have gone dead, but here was a new battery that wouldn't even take a charge. Hindsight is great, looking back I now believe that wiring harness had been causing me grief for some time. When I took the harness off the tractor, it was stiff as a board, brittle, and all wires welded together. I have two factors here, first I believe the old harness was slowly draining battery. With the switch on it created a dead short. Very likely the problem got progressively worse as he drove, couple the effects of a minor short, new 720 cranking amp battery, old wire covering probably melted along the way, making the problem even worse. These wiring harnesses are getting old, many have been saturated with gas, oil, anti-freeze, etc, at various times over the years. Not a bad idea to unhook harness at both ends, using test light one can tell if power is transfering from one wire to the next within the harness. Maybe we should just replace all this old original wiring. I have done it on my 130 and 140, my SA is yet to do, and maybe very soon.
