That's pretty much a regulation failure even at 14.8V. There's no good reason to pump more than about 14.2V out of any alternator. It just burns up the battery plates and may very well have toasted your ABS. If they actually built the alternator with that spec, I have no polite words for them.Code Pathfinder wrote: ↑Mon Feb 28, 2022 7:12 pmAlso told me that my Aftermarket alternator is outputting too much voltage at 15V or Higher.
The voltage set point on my 270 Amp alternator is 14.8 but it increases as I drive down the road.

The OE ground and hot cables are the same gauge if I recall correctly, and the current needs to reach the negative post. Vdrop there could definitely affect the regulator. Put a heavy gauge jumper from the negative post to the block and re-test the voltage rise, if it steadies at the 14.8 then that's your culprit. If so, install a heavier or auxiliary ground cable.Code Pathfinder wrote: ↑Thu Mar 03, 2022 7:13 amWith the new 270 Amp Alternator, I am running 1/0 Cable from the Battery + to the Alternator, along with the Engine to chassis ground and Battery to Chassis Ground. I do not have an upgraded ground cable running from the alternator to the frame so maybe that could possibly help as well.
