Big white resistor

[smcruisin]

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

anyone know? c'mon, I know there's plenty of folks with BJ-42's, could you just go outside and start up you cold diesels for me.

Thanks, Steve

Hello
I checked my resistor bolted to the left side of the glove box. Had my fingers on it and put my glow plugs on for about 20 seconds and it stayed cold. Temp 0 here. then after I started it I used the rocker switch on the dash and it still stayed cold. I would say this resistor does something else.
Because there is a big load when the glow plugs are on and they need the full 24 volts to work

thanks for the test-run waaz.

I'm back from my New-Years Party in Tofino, I guess it's back to chasing electrical gremlins...

Cheers,
