[diesel_mercedes] Charging Voltage on 71 220D

 



Mike ;


That's very good indeed .


As long as it remains above 13 VDC when you're on the throttle , you're good to go .


The proper charging rate is 13.2 ~ 14.7 VDC , measured above idle a little bit .


My fix after messing around with high output alternators was to use _ONLY_ Bosch branded voltage regulators ~ you should pick one up now and stash it in your glove box because when the brushes wear down you'll be stuck with whatever crappy " it's just as good as the Bosch one ! " junk the partshaus has and that _always_ charges too low no matter what .


Easy to change in one minute , too .

        Mike Asked :

Does anyone know what I should get from the alternator?  Right now when cruising under load I am getting around 13.5.

I have had no starts but should that happen when the battery is at 12.3?

Thanks you guys are great.

Mike
