Hey all, i've got a vortec swap (2005 lm7 5.3) in my 60, and noticed the shop that did the install did not wire in the Generator battery control module ( goes on the ground cable to the battery to measure current, so it can control the alternator output and increase or decrease accordingly for fuel mileage and faster batt recharge)
GBCM
For the guys that have done the swap, did you guys keep the GBCM?
If the GBCM is not operating, the alternator defaults to a constant 13.8 Volts.
Is running at a constant 13.8 volts an issue? Is it enough to charge up the batts?
I'm also running a Dual Batt setup, and question if this is enough to charge the start and the house.
I've upgraded my alternator to a 250 Amp mechman , and the resting volts have gone from 13.7 to a 14.1 which is better, but i'm wondering if that's good enough or do i need to get the GBCM sensor working.
thanks in advance! and here's my video of installing the high outtput mechman alt.
