Thanks everyone for your responses. The voltage at fast idle was 14.02V. Would a problem with the altenator cause the battery to lose charge when it is just parked? I must admit that I am not a fan of being under a car; would I have to raise the car up to get to the alternator? What do you think a nice MB mechanic would charge to change the brushes? I have been to the dealer to have the radio reset and he used a plug in key thing. The weather is getting nice and I want to get out on the road with my baby 300E. I am afraid to drive it and cause damage if I have an electrical issue.
Thanks,
Bonnie
