Glow plug relay question
I have a 99 F350 that won't start when cold unless plugged in. It starts fine after the initial start.
I bought the Haynes Techbook for diesels and I was checking the glow plug system. I had voltage at the GP relay terminal with the blk/orange wire while the key was off. I turned the key on and checked for voltage at the other large terminal (with the brown wire) and had nothing.
It stated if I had no voltage on that terminal, "disconnect the electrical connector at the base of the relay and check for battery voltage at the red/light green wire terminal, on the wiring harness side of the connector." Where is that "connector"? I see nothing that looks like a connector at the base!
BTW- I was hooking the ground side of my meter to the negative side of my battery.
