glowplugs

I have 2 questions I have a nova multimeter new glowplugs show 0 resistance the most of the ones in my motor show 0 a couple show .3 to .5 one shows no connection also will not light the test light(bad).
Should they show .5 to 1 ohm is my meter not good enough.
seems like I read where some of you use antisieze on the GP's is it safe to use.

Takes a good multimeter to show the resistance of glow plugs, they are very close to a dead short.
Dead short = 0 resistance.

The open one is bad for sure.

Since I am an electrician I have a high dollar Fluke meter.
But I also have a Micronolta 70 dollar cheapie from Radio Shack that does read them right.

On my meter the new ones I have show 0 resistance so it must be my meter my son somehow lost my snapon and I loned my fluke to somebody and dont remember who.
It has been starting fine didn't know there was a bad one and sure enough it was the last one on the passenger side under the turbo Can't never be easy.

Funny thing, everyone remembers where to borrow something, 1 out of 50 remember to bring it back when they are done with it.

The last time I loaned tools out, they never came back.
I chased them down and was told I never loaned them to them.

I don't loan tools anymore.

Checked my gp's today because I just bought a 93 with a 7.3 and the WTS light comes on for a couple seconds and then I hear the relay clicking under the hood. Most of the Gp's tested at 1.3 to 1.6 ohms does this mean that there bad? Seems like a difference of a half of ohm would not matter much. Thanks for any help.

Higher resistance, less heat generated.
Higher resistance, less glow time.

If it is starting OK, then run them.

But if it gets very cold where you are, you may have starting issues when the temp gets real low.
