My 1997 E300D while driving today had a battery charging light display on the instrument panel. My daughter was driving the car and kept driving for another 10 miles to the grocery store. After shopping the car would not start. I was able to jump start it easily. A voltmeter with the vehicle running shows 10.7 volts at the battery box in the in the engine compartment. The serpentine belt is tight and the pulleys are all snug. Can I assume the 90 amp Bosch alternator which is what is in the car.
