How much current are you getting from the alternator? I wonder how much current and voltage all of your addons consume. No way anything near 63 amps. I'd think the alternator was not putting out.

Guys some of the fans i've seen draw 40amps PER FAN!
A 63amp unit wont keep up with one fan that pulls that much,let alone duals.

Ok so got a new alternator today and it did not fix the problem. Now I'm reading 12.5 at the battery. WTF! There's gotta be something I'm missing here. There is three wires on the back on the post. One directly to the trunk battery, one that jumps to #2 on the plug and a third that the painless wiring kit said to hook up from the fuse box. Other than that the #1 plug is attached and said Exciter/Coil and that comes from the new fuse box. That exciter seems to be HOT even when car is off as I tested it down the wire away from the alt. Any other suggestions?

Time to troubleshoot.

Disconnect the wires from terminals #1 and # 2
Connect a 12volt filament (Not LED) light bulb from +12 to terminal #1
It should light. Start the engine. The light bulb should go off.
Check the voltage between the alternator output and the alternator case ground
Let us know what you get
