Thanks Db4690, Couger and GeorgeSanJose for your suggestions. I pulled out the battery and had it charged at Autozone today for an hour. With the ignition off the digital voltmeter reads 12.45V. With the ignition on and engine running, the Voltmeter reads 12.17V across the battery. So it looks like there’s no charge coming from the alternator.
I assume if this is a belt problem then there should still be at least some current from the alternator, so most likely the alternator is bad or there is a circuit problem somewhere. Alternatore fuse in fusebox close to the battery on the driver’s side is not blown. I couldn’t access the other fuses in the fusebox on the passenger’side. Is there like any charging relay i could check before taking the car to the shop to have the alternator replaced?
