How do the resistors go bad. I can see corrosion causing high or
infinite resistance, but can't see them shorting, unless to ground.
....as plugs go open on you in the CUCVs, yes, the remaining plugs
will see progressively higher voltage being applied to them, that
I have seen and understand.
>The CUCV uses 12v plugs and the HUMVEE uses 24 volt ones.
This is not so. Both are rated the same 11 Volts / 75 Watts of heat.
Just different ends.
In the HMMV application, they do away with the dropping resistor
BUT warn you that if the controller keeps the plugs on for more then
9 seconds, POP goes the plugs. They run 24 Volts straight to the plugs.
For those that retain the controller card on your CUCVs, wire in a lamp
to the glow plug SWITCHED power, (the side past the solenoid). Use this
lamp to eyeball how long the plugs are actually kept on. That "wait" lamp
tells you next to nothing. Plugs can be energised for alot longer
then they should be, or for that matter, not at all,
and you wouldn't know it.
