Welcome! In this video I go over how to troubleshoot the entire glow plug system in my 1989 Ford F350 7.3L IDI Diesel named Bertha. This includes:
Testing the glow plugs
Testing the glow plug grounds
Testing the glow plug harness
Testing power to the glow plug relay
Testing signal power from the ignition switch to glow plug relay
Testing the ground for the glow plug controller
And ultimately, how to switch to a manual glow plug system after you determine the glow plug controller is dumb and too clever for its own good.
