Ok guys, this problem continues to plague me. I replaced the one GP that was testing at 18 ohms so that eliminates that plug as a problem, but even before that and after the replacement I continue to have controller failure randomly.

I can pull the controller and clean the contacts and it'll work again fine, perhaps for several days, but yesterday it happened again and I cleaned them, controller worked and I got home shut the car down and went out today and no glow...so it essentially worked once. Most of the time I get a dozen glow cycles out of the thing before it shuts down...clean, reinstall and then it works. But this has to end, I cannot always be fighting this thing and I cannot believe that it's this unreliable.

Anything else on this I should look at before breaking down and buying a new one?

Thanks
Steve A
