Default Alternator Voltage Drops to 11.3 Under Load....Now What?
Thanks Yall for looking.



Should I get my battery checked? or should I not waste my time and replace the Alternator?


I have 120k Miles on the ALT and is 12 Years Old.


Thanks

Have them both tested, battery load and the alt. output.
Most auto parts stores will do this for free of charge.
Can not rule out bad connections at wiring junctions.

I would add to try cleaning the connections on the cables as well.

Very nice upgrade if you want the ultimate idling power, many here have used them.

At this point, I would not yet start replacing parts.
