Same thing I'm going through with my truck. Someone in another forum mentioned moving the thermostat grounds to the firewall and that fixed their issue. I haven't done it yet, but I did do a lot of other things that helped it. My truck would be below 12v at idle cold start, I upgraded my battery cables to 2gauge- added a battery to frame ground- power from alternator to battery- ground from alternator casing to frame. All wire upgrades were 2 gauge. Now at start up I'm above 12v on the dash gauge, the battery still dips with ac and blinker tho. I still need to move my thermostat grounds and see if that helps.
