Default What should the Normal Battery Voltage range be on a C5 ???

Before I washed the motor my Battery Voltage was a strong 14 V's.. Now it's hovering around 13 V's.

I've had no problems starting my car but I'm concerned that it might be a potential problem in the future.

Should I change my Alternator ?? The battery is only 6 months old..Its an OPTIMA RED TOP.

Thanks !

:cheers:

Washed motor? Maybe your belt's wet and slipping a bit?

No Codes and the belts are dry :confused:

I wonder if I damaged the Alternator when I washed my motor ?? I thought all the components were water proof.

Mine even goes down to 12.8 on the DIC. You can't really go by the DIC, you should measure at the alternator.

My DIC reads about 14.4 on trips. I cheked the accuracy of DIC against a digital VOM that had been recently calibrated. The DIC was very close.

Start a new thread. This one is 13 years old! Check the connections (alternator, battery, and starter) and see if they are loose or dirty. How are you reading the voltage?
