At this point, it’s logical and economical to replace the alternator. While replacing the alternator, also check all wires and connectors going to transmission making sure they’re in good shape and tight. Of course serpentine belt、water pump belt and belt tensioner (very common problem to leak) should be considered to replace too.Thank you everyone keeping an eye on this thread -- it is much appreciated.
Went to a different parts store and got the system tested again, similar results and their machine said the same thing: voltage regulator failure. They suggest a new alternator.
Looks like I can get a new one from RockAuto for $185 and the replacement looks pretty straightforward (except some of the weird bolt angles)
Will try replacing that and see what happns/report back!
