Granted, my auxiliary battery shorted out and I disconnected it before it damaged the primary battery and alternator.

But I was driving up the Golden Road, on my way to camp Friday night. Every time I key up and talk my headlights flicker like modulation lamps. I'm feeding my TNT 600HD with high strand 4 gauge cable. My truck came from the factory with 130A alternator. I hope that after I buy a replacement auxiliary battery, my power supply will be sufficient. If not, I see a 200A alternator in my future.
