M923A2 Ignition switch not engaging?

[newtotrucks]

Hello all,

I have a 1992 M923A2 that's giving me some trouble. I have had the truck since January and have finally gotten the Tag & Title from Georgia!!! I have had very little issues up until now. When I engage the battery switch on and then the first stage of the ignition switch nothing happens, (it used to alarm with the spring brake engaged) the switch does nothing... I replaced the ignition switch and it started for me twice I think. I thought I had it fixed, but now same thing, the switch does nothing. I do not have a clue as to what to do next???

Troubleshoot. Did you check battery voltage and connections? Could be a bad pcb box.

I'm betting on the PCB going bad. Try rapping on the PCB with a hammer.

Double check the PCB ground. It finds ground through the lower outside corner stud. If the paint is not clean off of all four surfaces ( the spacer, the box and the truck ) it will cause problems.

Batteries are good! I will look into the box...
