I am hoping a wiring guru will see this...
Quick background:
2H in a FJ62, glow wired to the defunct EFI circuit, glow is operated by using a spare defrost switch, timer light is from a HJ61.
This has operated with no issue for a long while...
Two nights ago, I climb in, flick the glow switch...and nothing. The switch light does not come on, the (20 second) timer light does not come on, no faint relay click, no movement in the voltimeter needle, no glow. Luckily, the truck was still warm and it started right up anyhow, no problem.
The next morning, different story. 50 degrees, took pouring near-boiling water over the fuel lines and glow plugs to get it started. No fun.
I popped the hood to see what I could see and jiggled wires, made sure nothing came unplugged. I saw nothing. Went in the cab and looked at the fuses. Yup, blown.
Now, keep in mind that the glow (again) was powered off of the old EFI circuit (since I no longer have EFI, it was a vacant spot on the fuse panel), which was a 15 amp fuse. The fuse was not changed (still 15 amp.). I popped another 15 amp fuse in there and immediately upon flicking the glow switch, it popped.
I put in a 20 amp fuse...same thing. I had no more 15 or 20 amp fuses and said "what the hell...." and threw in a 30 amp fuse.
Well, that keeps both the timer light and the switch light on and the fuse does not pop, but I still have no glow.
I was not the one to set up my wiring, that guy is unavailable, and I need some troubleshooting help here.
Do I check my relay, and if so, how? What amp fuse SHOULD I be putting this glow circuit?
What else might be the problem?
Let me know what more info is needed to go on to figure this out; if I know, I'll say so, but I know NOTHING about wiring and and intimidated by it, frankly.
I have accidentally kept the glow button in the ON position for 5+ minutes a couple of times, months ago, but that didn't seem to burn anything out. I have not done that in a while.
