Could anyone please tell me if you connect a multimeter between the tip of a glow plug where the live comes in and the body of the plug where it screws into the manifold should there be continuity? Many thanks. Richard

Hi, Ive never tested mine (because it works), but yes there should be continuity across it, but not a dead short. Put your multimeter on ohms setting, you should have a certain amount of resistance, like every heating element should when working ok.
Are your symptoms a) glowplug not working or b) blowing fuses/melting wires?

Connected the glow plug today across a battery charger and it glows red after 40 seconds so I guess its ok. Thanks for the reply.

Hi.
It really should glow red a few seconds after you put 12v through it...

For the sake of 20 pounds I just ordered a new one on ebay. Should improve starting.
