Have a 03 Peterbilt 379 with no power leading into the ignition wiring. Does anyone know where this power lead is distributed from or to? The fuse panel lead is hot. I need to track it as quick as possible.Peterbilt Ignition Wiring?
The circuit number is 388 (stamped on the wiring)
There is a junction just behind the MV3 valve in the dash. I have seen the studs in these rot out a bunch check it there.
Also, there is another circuit in Peterbilt's main harness (388x-1) it should be abandoned next to the rest of the wiring. You could use this circuit. It was for a A2 option package... if it is there, simply replace it... it will work fine. However, if you do, also make sure you pull the lead from the 388 out of the fuse panel in case there is a short in that harness. Don't want any fires! Good Luck!Peterbilt Ignition Wiring?
No sorry I don't know but I suggest that you disconnect your battery soonest if fuse panel lead is getting hot.Peterbilt Ignition Wiring?
By hot I believe you mean it has voltage to it.
If you mean hot by temperature then yes by all means disconnect the battery.
If hot with voltage you need to test the B+ terminal on your ignition switch. If that is also hot you need to get a shop wiring schematic so as you do not do more damage than good.
Today's systems include an lot of electronic controls that can be damaged by something as simple as a test light.
If you are not a mechanic, take it to one. It may save you hundreds or even thousands in the long haul if you damage the computer.
