So I've got the stock alternator on the Fury and I believe it's 60 amps if not mistaken. I have working A/C and when I'm driving with my headlights on, A/C on and come to a stop I can watch my dash lights start dimming while waiting for the light to change. Once I'm moving everything brightens back up and we're good. I've tested the alternator, the battery and recently installed a new voltage regulator. There are no broken or damaged wires, belts are all new and tight. The alternator charges the battery when the A/C is off nor will the car won't die when it's on, but the voltage drops sub 13 with medium or high blower speed. I've gone as far as to remove the alternator and battery and have each tested at various supply stores in my area, all confirming they are both in good working condition.
My question is this, is it possible that the alternator is simply underpowered and bumping up to a 75+ amp alternator would solve the issue? I've also considered it could be the A/C clutch but wanted to get some background on alternators for these cars and if they historically have had issues with being underpowered for cars with accessories.
