Glow Plug Wire Burnt
Hope someone can help me out with this one.
Started the truck this AM, mass smoke came out of R/S firewall. Shut it down, looked like some wires had shorted out, melting the insulation off.
Looked further, and looks as if the 2 positive wire coming from the battery attach to a power relay on the right side of the fender. From there the wires going to the GP controller feed off. What happened is that one of the 2 hot wires feeding the GP controller (not one of the 2 from the batts, the black w/gold striped wires) got hot enough to melt in half.
Additionally, the negative/ground that comes off the battery, attaches to the power relay, than grounds out on a terminal next to the voltage regulator, and also on the chassis, had it's insulation melted off as well.
The truck started up fine, afraid to start it now. When it started up before, (when the wiring melted) the battery light stayed on, and the voltmeter registered zero (hard left).
Any ideas? I'm guessing that what the wires attach to is a power relay, but I didn't think they used these on my model (just 6.9's).

From: qualcum beach bc
if it was me before i tried to start it again i would disconect all the gp stuff from the batt and then i would pull all the gp.s to check that the tips are still on
i dont think pistons and valves like them to much
good luck
