Did u by chance bench test the bad GPCM to see what readings you might get compared to the good one? Seems like that could be useful information to have if you ever wanted to test a module without having to go through all that setting up of the parasitic draw test. Just a thought, I may do it with the module on my 04 F350 since I think mines toast. If I plug it in it'll drain my batteries in minutes. I live in California so It hasn't been a big priority to get fixed. Great video man, I see it helping many 6.0 owners in the future, it helped me today.
I have found that the faulty gpcm will show heat with a thermal camera. There has been a couple of these issues in our time and now I just touch the gpcm if it is in question. Normally if this is it,, you will feel it being warm.
Good video but a few helpful tips is start with the fuses and relays in any pdb's first before ripping interior stuff apart. Also, the jumper wire to prevent any modules like the pcm from waking up isn't really necessary, you can simply wait a minute for any modules to go back to sleep.
I think this might be my problem. You described the my situation almost to at T. replaced injectors, next day the battery was dead. Found if i disconnected the alternator cable, the draw went away. Replaced the alternator, still drawing. Wanted to replace the alternator cable, but since the glow plugs are integrated with it, i don't think that is a solution.
Anthony, how often do you see the problem (soldier joint in circuit board cracks) on the trailer brake module on the 2000’s 6.0L super duty? I fixed mine already, just wondering if it’s a common issue you see where the one solder joint breaks and needs re-soldiered.

He edits now, I like it.

I’ve fixed several for customers. See it quite often.
I very rarely,,, actually almost NEVER mess with circuit boards!! I do have a stack of tbc modules,,, lol
Thanks for vid
keep up the good work
Awesome thanks brother
