I would suspect that your attitude and language would have offended said truck... There are a multitude of fixes for the glow plug system and they are in the archives of several of the lists... All that you have to do is actuate the glow plug relay manually by means of a momentary contact switch.. However, if you have already tried everything, that means that you have done that too.. Of course the plugs may be fried, but you have probably taken them out and checked their resistance individually on the bench to be sure they are OK...Fuel getting to the cylinders? etc etc etc...then, lastly... in the manuals which all MV owners should have for their trucks, there is a wonderful section on troubleshooting the glow plug system... the Manuals are the TM 9-2320-289 series...

just search the forums for "manual glow plugs" if you have any issues feel free to ask, or catch us in chat.

I put that i am in NJ. its there guess it didnt save or something. ill try again. need new wireing i think guys. i did what the tms say and some other people. Everything is new still will not fire. this is all i can come up with.

cut the light blue wire that goes into the glow plug control card. It is a rectangular piece of plastic with a bunch of wires coming out of one side. Ground out the side that goes into the card, and take the end of the wire that goes to the solenoid and wire it to your switch.

 

[CCATLETT1984]

you dont need to ground out the side of the wire that goes into the card.

wire up the other side of your switch to a good ground, but the rest of the instructions are spot on. Post up if you still have issues and we'll help you through troubleshooting

sorry to say guys. i tried all this does not work. need new wireing i think.

 

[CCATLETT1984]

If the wiring change doesnt work, then you need to check that the glow plugs are heating up, check that the glow plug relay on the firewall is supplying current to the plugs when you hit the button. If you get voltage then you need to start checking the glow plugs to be sure that they are not burned out. you can pull them and just hook a wire to the blade connector and hold it on the positive terminal of the battery and touch the body of it to the negative terminal. If they start to glow then they are still good.

Wellman says the 070 is the THE plug to use in a stock CUCV. The best place I have seen to get them, is ind-usa on ebay

here is a link to them.

Wellman glow plugs are self limiting, ie. they won't blister if the relay fails and a continuous load is applied to them. They are a much more reliable glow plug the the original AC13G's.
They claim the military uses them. Ok, everybody makes claims... But, two of my cucv's came with 070 self-limiting Wellmans when they were released from the government. So the military does use them. SSDiesel carries them also.

when i got my cucv. the pluges where stuck in there. these will do that or not? would like ones that dont if i can.

 

[CCATLETT1984]

These plugs WILL NOT SWELL. they are self-limiting so they dont overheat and droop.

 

[acetomatoco]

remember that the original wellmans were bad swellers... Your best bet is still the Chebby dealer for new ones... AC 60G... ACE

 

[CCATLETT1984]

the ac60g's will burn out quickly in the cucv, since at initial turn on they get hit with ~18volts until the resistor heats up and brings the voltage down to the 12v range.

 

[84cucv1ton]

thats why my 60gs went bad. damn, thanks again
