Why is my LR discovery glow plug not working?
LR Discovery had a known a problem with the glow plug relay wiring going brittle and breaking up. Usually this break up would also spell the end of the relay. You say the wiring fell apart and is brittle. Run some new wire end to end and fit a new relay. Aug 26, 2012 9 I have fit new wiring to the relay but am yet to replace it.
What should the voltage of the glow plug be?
The single heavy red wire term should be 12v all the time. The double heavy red wire term is to the glow plugs should be hot 12v when you hear the relay click on. If no voltage the relay is bad, Pin A battery voltage, key in run position, all the time ( this is feed by the 20 amp fuse ).
Why is the glow plug not working on my CDI?
After driving 100 miles, stopping, and then attempting to restart it after around 3 mins, this is when it wouldnt fire. Any info much appreciated. I might be wrong but a CDI should not need glowplugs in the British environment, IIRC they are mainly fitted for better emission control after the engine starts.
What to do when glow plug light won’t go off?
Either replace the controller or wire in a manual button to run the relay. The inhibit switch is on the opposite side near the same spot and has a two wire plug. The best thing to do with the inhibit switch is to jumper the plug and forget that thing.

Why does the glow plug light on the dash quit lighting?
On the water manifold/ t/stat housing is a temp sender this is for the ECM it could be bad and it is telling the ECM the engine is hot and does not need the glow heat. Easy test unplug it and try starting it, unpluged the ECM thinks it is stone cold and it will glow for a long time.

Why are the lights not working on my Merc Van?
Have tested battery: no key in- 12v, key in and ignition on- 11.9v, key turning to crank position- 11.8v. All dash lights light up as normal when key on except for glow plug light which never comes on now. My mate works for a van and truck company and his software works on most merc vans but wouldn’t talk to mine yesterday.
