I have a 96 Fzj80 and I just swapped in a 6.2 diesel. I am at the point where I am just running it in the garage to work out bugs. Finding lots: I installed a ford starter relay so I can manually heat my glow plugs. After running the engine for a bit I shut it off and started working on bleeding my brakes. When I went to start it again about 20 minutes later the batteries were dead. Brand new batteries. So I started hunting for where the draw is. I touched the relay and it was red hot. I found that power was still going through it and heating the plugs.
I am having a hard time believing that I got a bad relay but that is the only thing I can come up with. I've checked the wiring and its correct. I have a large gauge wire going straight from the battery to the relay like 4 gauge. Could that be causing it?
Any ideas?
