Thanks!!!!

So it’s sounding like a ground issue then I’m assuming? I was having intermittent cruise control issues as well so that’s the main reason for doing this mod/upgrade as far as that’s concerned would that possibly fix any ground issues I may or not be having? Just need a base to start with more or less. I know the voltage regulator is in the pcm so that’s why I was questioning it as a possible problem

The 140 amp fuse is there and it’s good.. I’m getting 14.5 volts at the batteries and the stud off the new alternator I installed last night.. nothing crazy as far as electrical modifications go, it does have an aftermarket stereo and speakers w/subwoofer and amp. Those connections and grounds I’ve checked already and they are fine.. that’s why I was wondering if it was maybe a issue elsewhere.. I disconnected the grid heaters and turned off everything that would pull voltage and the alternator is still putting our 14.5 volts at idle.. shouldn’t the pcm engage and disengage the alternator after batteries see a certain voltage?

New to the site and found the info to be amazing.. will be doing this upgrade soon now that I know it’s an issue.. but I’m having a major problem with melting the stud off the back of the Alternator.. would this upgrade possibly fix that problem or is it a pcm issue? Please help and thanks in advance
