12V GP Relay Conversion...quick question...

[Asmoday]

I was reading as many of the posts I could find on the 12V GP relay conversion but I didn't find the answer so a quick question...

Do you have to replace the glow plugs at the same time with AC60G's or the like when you get rid of the resistor and do the 12V relay mod or can you do the mod...relay, wiring, resistor removal etc. and then replace the glow plugs themselves at a later time?

Thanks...!

The resistor drops the voltage from 24 to 12 volts and the glo-plugs receives that 12 volt voltage.

Your glo-plugs are 12 volts, so no need to change them because of the relay conversion; however, a good idea to change them because after one burns out, others "tend" to follow suit rapidly and also by changing them, swollen tip removal problems are minimized. Put a bit of anti-seize paste on the glo-plug threads and don't over-tighten them...

The 4 CUCV trucks or engines I have gotten from the military all had Welman plugs in there. About 2 per engine have been swollen and very tough to remove. Many times people suggest putting in the 60G plugs because they are a better product that does not swell.

That along with the above post about how you already have 12 volt glow plugs in there should take care of your questions.

The AC Delco 60G's are nice plugs. They are self limiting and shouldn't burn up or swell as bad as other plugs. I have had great luck with them so far but time will tell I guess. Just my

Great info...Thanks for the replies...!
