Agreed. I'm keeping the factory stuff exactly as it is and am adding a new "homemade" ground to the frame from each negative battery terminal.
So far, so good. Haven't had a chance to add new grounds yet, but I also haven't seen anything weird either. Truck is down for a new oil cooler, a/c repair, and a couple of vacuum leaks that need to be chased down.
I called DB Electrical about my refund (it was being submitted that day) and they let me know the alternator I sent back had a bad stator.
