1HDT GLOW PLUG LIGHT FLICKER

[oldandintheway]

Hey there, owner of a 1990 HDJ81

After short or long drives, post-warm up I've noticed zero dash lights except after I shut down the truck. About 10 seconds after truck is off and key is out of ignition, my glow plug light slowly flickers on and dimly flickers for a few minutes.

Any help diesel heads?

i can't imagine it being anything other then the timer. Unplug it and see if it still does it real quick to test.

Confirmed. Thanks for the speedy response. Cheers!
