Through searching the forum I believe I have my issue narrowed down to a bad GP relay on my 1981 300 SD. My supposition I would like confirmation on is that the relay is supposed to receive power anytime the key is on, both during the glow cycle and while the engine is actually running?

To put it another way, the relay is receiving power at all times the car is running. It is the relay that opens preventing power from going to the glow plugs after the glow cycle. Right?

The answer/confirmation of this will confirm that I am not getting power to the relay when I shouldn't.

Thanks

BTW, I appreciate the new spell check feature. Thanks Hunter
