Re: (ET) All fixed



That is a possibility, but I removed the tap wires to the lift and the lights from the pack.

Whatever it is, it's a big wire: I incinerated the wires in my deck when it developed a ground fault back in the summer. No damage to the tractor.

Think of the double contactor replacement as an occupational therapy exercise. Increases dexterity. <G>

Swapped out the contactor pair with a spare set and the tractor is working perfectly again. I'd still like to find that other ground fault though; any suggestions on how to track one down? The only clue is that it's there even with the main disconnect off, and it's pretty persistient.

Another thought: Pulling those contactors is a real 14 karat pain. However I do like the fact that one can fix just about anything on a contactor based elec-trak with a meter and a set of wrenches.
