Glow Plugs 1985 300SD
Hello Everyone,
I have done some research and did a few checks on my car, but once again it is getting pretty cold around here, 5 degF for the next few days, and I need to try and get this figured out. Lately, the glow plug light has been working intermitently, now it hasn't worked in the past few days.
I have done the following checks:
1. 0 ohms on every glow plug, from relay to glow plug
2. Voltage at each glow plug wire output on the relay (12.42 V)
When I unplug the glow plug wires from the relay, the light on the dash comes on like normal. When I plug the wires back in, the light does not come on in the dash. I tired this multiple times with the same outcome.
Is it possible that there are 1 or 2 glow plugs which are shorted out?
I am wondering if the relay is an issue or if there are other ground wires which might need to be cleaned? I don't have an electrical schematic at this point in time.
Any help is greatly appreciated.
Thanks,
Keith
