I'm not convinced my glow plug system is working correctly. Details:
1982 BJ42 (12V electrics) imported to Rochester, NY where the temps are currently in the 30's (F).
When the engine is full cold, I turn the key backwards prior to starting. This activates the glow circuit - I can hear the relay click and see the battery voltage drop to ~10V (truck has a voltmeter).
The glow plug controller takes more than a minute to start glowing. When it does glow, it is so faint that I can barely see it. During the daytime I can't see it at all, no matter how long I glow. At night it's not much more very dim orange.
If I glow for 60 seconds or so, the truck starts fine, so that's how I've been working it. I saw a 24V BJ42 last fall that would glow like a flashlight!
Why doesn't my glow controller heat up very much?
I did pull the plugs for a visual inspection and to insure good contact. Champion part CH121, 8.5V, 8K. I've searched the archives and it seems 8.5V are the correct application here.
Thoughts?
