Until the smoke comes out :-)
When I had the GE contactor controller, I was forever fixing something,
either a semiconductor on one of the cards or the burnt reversing relay
contacts. The final straw came the blustery winter's day when I was
plowing
and had to reverse the tractor by raising the hood, lowering the relay
panel, and pushing on the reverse relay.
So far my E15 seems fine; I've been driving it around the yard without a
rear battery box, towed out the Craftsman from the woods, that sort of
thing. I'm probably going to sit down and build a quick interlock so
that it won't toggle the relay if there is *any* voltage on the armature
line, that should fix any arcing.
You can certainly rebuild or replace the various components of the GE
controller, and that will probably improve its reliability. However, IMO
it's not worth working on. If yours works, I'd say use it until it
doesn't,
and then rip it out and put in something that wasn't developed in the
Apollo
Space Program era.
The Apollo people got to the Moon. The Columbia people consider it an
accomplishment to make it to the space station. No contest there.
But as you'd expect there are plenty of opinions to the contrary here. ;-)
*laugh* It's what makes the group go. I will say though that the E20
controller is a much better design than the E15; it's even less
technical; pretty much impossible to blow it up.
