Returned it to Advanced Auto. Did the bench test & it passed 4 times, did some digging & found out wrong alt because the original had plug input 3 wires at 12 o'clock position & the replacement they gave had plug @ 4 o'clock which put the plug right against the valve cover & a ***** to install.

So I get the correct one & install, have the same problem. Voltage is either reading a 1 or like 0.5. So I figure bad ground.... ran a wire from back of the alt to the ground strap at the fire wall & still the same readings . Also tried to loosen / tighten belt to eliminate that, still same readings of the back of the alt. I checked the 3 wires coming off the plug & red goes ties into main red coming off the back. The other 2 both tan, 1 looks to lead back to the instument cluster ittiot light. The 3rd goes to a small silver electronic box on the passenger side of the inside fender just behind the battery, don't know what it is or if it can be the cause? Please someone
