Alright guys I am having problems with this install and really need some help. I wired everything to the alt. The truck starts fine and hits high/warm-up idle but it never quits when the engine temp gets warm. The charge light and brake light are both staying on and the battery has less voltage after the truck is started. Im pretty certain the alternator is wired up correctly. From the voltage regulator harness I used the red for ignition and yellow for the charge light circuit. And for the "sense" I ran it straight to the battery post. Triple-checked all this in my FSM and seems right. Now when the key is turned to the ignition position but no engine on I get voltage on the sense and ignition wires but none on the charge wire. I would chalk all this up to a bad battery or bad alt but the idle thing makes me wonder otherwise. Any help would be greatly appreciated.

I have been following your thread. Is there any change in status?

Yes look at the thread called GM Alt Install Problems. Everything works now except for the charge light.
