I'm re-installing the wiring harness in my '81 BJ-42 and managed to get enough hooked up to start her up on Christmas eve!!! I don't think I warmed the glowplugs for long enough, compounded by bleeding the fuel system..... needless to say my family and neighbours weren't too pleased with the copious black clouds of DIESEL smoke!!! (add the fact that there was only a meter of exhaust pipe past the manifold -- Yeah! the dragon roars to life!!!) Anyways, we noticed the big, ceramic resistor on the left side of the glove box (under the dash) got REALLY HOT (you would get burned if you held it for more than a split second)!
I think it has to do with the glow-plug circuit (relay etc). I don't remember this relay ever getting this hot, though I also don't remember ever feeling this resistor during operation. Can anyone with a working BJ-42 comment on the 'hotness' their resistor during glow-plug warmup?
I also burned through one of the three wires in the fusable link, and I suspect that may be related to the hot resistor... only time will tell.
Thank,
Steve
