#2 Diode to PCM Mr. Mike T. Please help
Hello to you all.
Mike can you help me please, infact does anyone know why my
#2 Diode for the PCM blows out on me. Which is located in the power distribution box. I mean all that is left is the 2 spades and then the engine does not run of coarse.
This is the second time. The first time it had blown right out and I replaced it and I checked it last night by changew and all the black plastic has been burnt off of the diode exposing the inside ( looks like a transistor or something) but it hasn't lost contact yet.
What is the purpose of this diode?
Would the chip be causing the problem?
Need help soon don't want truck to burn up, Greatly Appreciated
