1991 7.3. I just read the sticky and learned quite a bit. My truck has been parked for a while so I am trying to say this off of memory. When my GP system worked, my light would come on for about 8 seconds then a few after that I would hear the clicking of the controller cycling. Seems at the time I asked about this and was told it was normal. Once the truck was warm, never saw the light.

At some point my fusible link burned out and they quit working. The repair at the connector had been done by a previous owner, but it needs to be taped up. I do remember the connections touching at one time and I just spread them apart at the time to stop that. Don't know if that caused damage.

Me being weak on electrical I enlisted a friend to look at things. We thought the system was shorting because we were checking with only a 60 amp ammeter not knowing they pulled 200 amps. At the time I thought having all 8 hooked up created a short (because the needle would obviously blow off the scale). With only 7 attached it did not do that so I ran it with 7 for a long time and the truck started fine.

My fusible link would get hot and finally break. Obviously the plugs don't work now. I used a block heater for 2 years. I finally have the fire to get this thing back on the road so I read the sticky. I looked at everything and the insulation around all of the GPs is gone (bullet connectors). So am going to repair that and test all of my plugs to make sure they are still good. Can you guys tell me where the GP relay is mounted on the engine and what could cause those links to fry? I just looked and the link that fried is the one integrated in to the black wire with yellow strip that goes to the + battery terminal on the starter relay on the firewall. The large post.

Or do I just convert to manual and be done with it? Thinking of that, but would honestly like the challenge of fixing it. Thanks all, this forum is the best!
