Are these the right glowplugs

[LTWVARNG]

Has anybody ordered these glowplugs? They say they are wellman 070's but 24V?
Thought they were 12V. Or does anybody have a better source? I'm getting alot of white smoke in the cold mornings. I think it has to be a few bad plugs.

For an intact, unconverted, original 24v CUCV, yes, those are correct. You're good. A few sources on ebay. They all seem to be about the same price. Yes, they are in fact rated at 12 volts as in theory, the big resistors on the back of the firewall reduce the 24v to power the gp's. In reality, they apparently don't reduce the voltage completely to 12. More 24v CUCV vagueness... I found that out the hard way when I converted mine to 12v after buying a new set of 070s and nothing worked. 070s though rated at 12v and appropriate for a 24v CUCV, won't work in a pure 12v system. Thanks to Doghead for that tip...

First of all, check the plugs before you go to the trouble of getting new ones. The quick and dirty method is to disconnect the glow plugs. Then take the clip end of a test light and attach it to the pos of the front battery or the neg of the rear battery. Then touch the terminal of the glow plugs with the probe. If the test light lights then the plug should be good. Another method is to measure the resistance of the plugs between the terminal and ground. Most of the time a bad plug is shorted internally and will not make a connection for the test light.

To answer your question directly, Wellman 070s are the right plugs. They are for the 24 volt system even though they are 12 volt plugs. The wording on the web site is misleading. They will have the correct terminal for the cucv and are the correct voltage.

You might also check the electrical trouble shooting area of the -20 as it has a step by step method to check the entire glow plug system. It only take a few minutes with a multimeter.

Yeah there is soo much to learn on these things for as simple as they are supposed to be!

All mine light up.....hmm wonder what the smokes from....probably way too much 2 cycle engine oil

I'm very happy with these.

Not quite what I said.... The stock cucv 070 glow plugs will work with a 12 volt converted system.

M1009 and M1008 Glow Plugs

They are right, they are 12 volt glow plugs. The problem with the system is that it was designed to work in extreme cold conditions but due to the way thses are wired if you have 2 bad ones it will cause a rise in current to the remaining 6 and burn them out sooner. I own 2 M1009's and a M1008A1 and may son has 2 M1008A1's and a M1009. We have removed the resistor and run the glow plugs from the 12 volt feed on the firewall. They work fine and only take 2-3 seconds longer to heat. "How to". Remove the lead on the right side of the resistor that runs to the solenoid and connect it to the black (ethier side) terminal block located on the fire wall. Nothing else need be done. Since converting ours over we have had to replace a single glow plug.

My apologies for the misquote and or attribute, Doghead. You've been a big help to me anyway...

 

[Sgt Hulka]

For the record. The new Wellman 070s did not work to any degree in my converted 12v. The Wellman 050s are fabulous...

So would a set of one of these work in a stock 1009?

i would get those wellmans on ebay, but I have to get my truck running really soon, getting out of utah for a bit and partying in nevada for the weekend. a local checker has those plugs, just not sure which ones to get and if they will work on a stock cucv.

AC 60Gs DEFINITELY...

 

[steve87]

I just installed the 60Gs this morning, man was it cold out. I had to cut the wires and put on a new ends to fit the wider spades on the new plugs but the truck started up fine. It has only been one day and working fine. Just glad to get it running with all this snow here in Utah.

 

[Sgt Hulka]

Congrats! I know how good it feels to get it running after a vexing problem...

I was going to say WHAT, Ever since I bypassed the resistors to the 12v diamond shaped terminal block right next to the gp relay My trucks starts fine.
The wellman 070's are the ones to use bypassed or not. Changing the green wire female spade ends from 3/16" to 1/4" allows you to continue to use the wellmans or use another glow plug of your choice as Doghead has stated.
Use the weather proof 1/4" female spade type and heat shrink them after installing - new ends and sealed - thanks eric for the tips
one plug type that is said to be better than wellman 070 -
after doing resistors bypass is the wellman 050
thanks mike for the tips
