Testing glowplugs?

[Dazzy2006]

After snapping a glowplug last week i've left the car alone until today. I decided to test the resistance on the glowplugs

2 glowplugs measured 1.3 ohms
1 glowplug measured 0.6 ohms (which i assume is the duff plug)

The snapped glowplug read 1.2 ohms so i think if i get inventive i might be able to bodge i mean repair that one

Can anyone confirm what sort of resistance readings i should be getting

Cheers guys

As far as i know bud,the resistance of a glow plug in good condition is very low(less than 1 ohm) so on that score it would appear that the 2 reading 1.3 oms are duff ones,and the one reading 0.6 is the good one.

oh well suppose its plan b then - dont know what plan b is yet but hey i own a vectra so i'm sure i'll think of something

Yep the resistance should be really really low. The higher the number the more resistance you have

Have a look at the above

Right now i'm totally baffled - took a look at the above, then i just tested 1 of the new plugs and that measured 1.4

If its over 1 ohm its knackered they should read 00.5 ohms mine read around 00.7 ohms when i tested mine , So i believe they are ok...

I think i'm going to go and check whether i have got my multimeter set up properly

Set it too this

[Dazzy2006]

right, just checked the new ones again. My multimeter is a cheap one so i set it to 200 in the ohms setting and there measuring

0 1.4

and if i set it at 2000 they measure

0 0 5


so i guess i had it on the wrong setting
