I was driving in hot weather up hill last week (dont know if temp related), when the "Check Engine" light came on, I noticed the volt meter was all the way down to the left most line (same as engine off position). When I arrived at the top and started on the decent; I noticed the overdrive does not work (auto trans), also the cruise control is not working, and the trans appears to slip on take off. Referencing the PCM (power control module) info; the pcm controls the above items, I have not noticed any other items on the list malfunctioning. Before I spend $400 or more for a new pcm, I would like to make sure it is the module or bad connection, ground... What is be best method to confirm the pcm is good or bad? Or is there something else that could cause the above problems? Brian

I know there are some of you that dread the day hen the voltage regulator gives up the ghost because you know the PCM has to be replaced... Well I dug up the information and artwork for doing a old school regulator to replace the PCM function. http://mopar.mopar1973man.com/cummins/general/voltage-reg/voltage-reg.htm
