[QUOTE="W0n70n, post: 1649180, member: 44703"] There is, it involves making sure the truck is off and fully asleep (no key fobs nearby or doing anything with the truck) for 8 hours and the system will read the new charge level on the new battery, I think it can also be reset through Forscan but I can't remember right now. The issue is that no amount of messing with the PCM will make a generic autoparts store alternator work in our trucks, I don't know if it's a tolerance issue or a small difference in parameters between SVT and regular f-150s or what but I tried 3 "new" parts store alternators and none of them, new and tested out of the box, worked for more than a few hours. Swapped in a new Mechman alternator and it instantly worked perfect and no complaints since. [/QUOTE]
