I have read just about every glow plug thread I can find on here and cant seem to find anyone else that has encountered this problem.
I have an FJ45 1975 chassis, with a 88' model 2H motor. The previous owner did most of the work, however he sold it before rewiring.
I have used the FJ chassis wiring loom, and then fitted in a seperate loom to run the EDIC and Fuel Control Relay - that is done.
I also created a seperate loom to run the glow plugs using the heavy gauge wiring out of an HJ45 loom.
My problem is that I was starting the truck the other day - with a very low battery - and the extended slow cranking meant the glow plugs were left on for around a minute or so. This caused the wires to start smoking. When they eventually stopped, from what I can see the smoking was coming from the wiring going to the convertor coil in the dash.
It would seem to me that if the coil can glow red hot, then does that not mean that heat can conduct down into the wires connecting it - and cause the problem I have just had?
I would have thought that any wiring should be such that it can be left on without any risk of causing a meltdown.
So, my question is, have I wired something wrong, or is this just what would happen to any vehicle with this convertor in place if the plugs were left on for so long?
Ive attached an image of the wiring diagram I have based the glow plugs on.
