Does anybody know what the resistance should be on the grey glow plug relay 04 2.8 crd please.

 

Dunno, I am Chrysler "noob mechanic" and looking to see if the relay or fuse for my auxilery heater is broken or not, cant find it until now, but I did find there is a spare relay placed in the fusebox (see inside the lid of the fusebox), so maybe you can switch your glow plug relay for the spare one to see if that solves your problem?

 

Thanks vmaxxer i will give it a try my aux heater has failed too so has my heated drivers seat and drivers electric mirror. If when i fix the starting problem i will start on the other stuff including the brill thermostat fix i found on here. In the meantime iam going to buy some thermals and shares in easystart. Have a good day

 

do you mean the resistance of the coil of the relay, or the resistance of the glow plugs?.

The glow plugs should be less than a couple of ohms each, not sure what the relay coil is but 1A at 12V is 12 ohms so, anything from 10 ohms to 1000 ohms should be fine, with the most likely range being 10 to 50 ohms

So what you guys think..can i take ordinary relay from fuse box and use it as glow plug relay..or do they have any power differents?? i took my glow plug relay out today and there wasnt any differents on starting up at all. and looks like one relay connection has slight melting sign.

 

no, normal relays tend to be around 32 or 40A rated for the contacts. Glow plugs draw a lot more than that initially, though it will drop down as the tip heats up.

Generally a CRD doesn't really need glow plugs to start, unless very, very cold.
