Big 3 done today. Think it got worse. Voltage drop is so bad when the fan kicks on it's almost like the motor is dragging. It spins freely by hand and when you up the rpms it starts better but still a large drop.
Do you have any added electrical? Like an amp?

Yeah. I have a amp installed. I've disconnected it and still have the same drop. I'm beginning to think it's the fans. They are new but Dorman. I'm going to try and get a set out of a truck or tahoe and see if they help.
