Need some help guys

[mhuppertz]

Today leaving a client site my power cut in the truck and a bunch of smoke came out of the top of the dash and defroster vent. I still had interior lights and brake lights, but not much else. I found some crispy wires, and also found that the middle bus bar on the back of the fuse panel was live, but the outboard br was not. I jumped a wire over and then could start the truck and everything worked, as long as that wire was there. When I kill the truck I have to pull that wire because the electric fan and some other things keep running otherwise.

I am assuming a fried a fusable link, but am having a hard time tracking down link locations. I have the FSM, but it's still a daunting task.

Any advice?

Thanks,

Mark

Since the smoke came out of the dash, I lean more towards a problem in the cab. Maybe the ignition switch burned up? It may have fried a fusable link also.

All your key-on stuff underhood is connected through the same wire. My AC clutch hot fried one night and wiped most of my in-cab stuff, then my reverse light hot shorted and took out almost 3/4 of my harness. It'll still get to the light blue wire that comes off your key switch if something underhood shorts out.

The switch is still working for some stuff liek the power windows. Hoping it's just that fusable link.
