Truck Dies 7.3L PS

[RodM]

1997 PS Crew Cab 7.3L When I apply my trailer brakes through the controler slider bar the truck instantley dies, The truck also dies perodicaley when the drivers door is opened.

Have isolated the trailer from the truck and the same thing happens when the slider is slid to full brake position.

Has anyone else experienced a similar problem as this one.

That is a wierd one. Anyone got any ideas?

Rod, does thr truck have any starting problems? Could there be a bad battery or alternator connection?

[Ronny'02-7.3]

OOPS. "The" truck. I would also check grounds to the body. Bad grounds do strange things.

That REALLY sounds like a ground problem.

diesels are notorious for demanding a good ground...

My Guess is you have the power supply to the brake control connected to the IDM power supply and you are grounding the injector driver when you apply the brakes. Tomarrow I will pull up the wire diagram and see what else might do that. Mike OB
