[QUOTE="MalcolmV8, post: 15753947, member: 8854"] Just FYI when autoparts stores and even real alternator shops test alternators it's at a much lower RPM and doesn't simulate WOT conditions. It's very frustrating as I've been down that road with low voltage at WOT but everyone keeps insisting the alternator is good. Swap out the bad unit that everyone claims is just fine and boom problem fixed. While probably rare alternators can put out good voltage and current at low RPMs but fall on their face when spun hard.
