testing alternator while in car

[Shady]

@deadbeatrec

just went outside with a multimeter and…

everything off, the new battery reads like 12.37v

car on with lights on and radio blasting, the battery reads 14.18v

i think im good.

thanks for nothing shift.

That works just fine…

The only thing the pep boys one does is just put a huge load on the altenator to see if it dies under a big load…
