Eh, my previous DD was a 94 Oldsmobile Cutlass Supreme 2 door with the 3100. I still have it actually and drive it most of the time. It's not in the same class, but it does just fine.

Starting with the battery current sensor, i talked with the master tech at GM when i picked it all up today and they explained to me that the stock sensor on my car (GM part #10306471) was a known issue with the cars that it was installed in from 2005 to very first off the line 2007s. Then it was superseded by GM part #13505369 at that point which is supposed to fix the issues. continuing my talk with him the purpose of said sensor is to help regulate the power in the car from the alternator and also provides the voltage the the Drivers information center shows. (Didn't ask how it works didnt really care lol). Also when i told him that sometimes when i have the alternator tested when the cars electrical is acting weird the regulator in the alternator shows being bad and other times it didn't, well guess what....this stupid piece of crap sensor can make it appear so to the simple testers that it is a bad alternator...go freaking figure. well hopefully this fixes my problems when i stick it in tomorrow!!

It sounds like the way to get the GXP alternators tested is to remove them and have them bench tested.
