testing alternator while in car

[Shady]

@deadbeatrec

how can i do this?

i called pepboys and they say they have a scan tool that will run through the whole system. but i find it hard to believe that it will target the alternator specifically.

thoughts?

From in the car all the will be able to tell you is volts…

Theyd have to put a battery/altenator tester hooked up to the battery and put a load o nthe altenator to see if its bad or not
