Is the Alternator dead? :-(
Car: 300E 1990, mileage unknown - recent purchase
Here's what I know ...
Should I just replace the voltage regulator? Thanks for the help. I did a search - didn't see a hit. Thanks.

how exactly did they do this "load test?" usually when you're doing a charging system inspection, you rev the engine to about 2000rpm or so and then apply a load to the charging system to see its max. amperage output. did the car die even though the revs were held up?
if you're having to jumpstart the car three culprits come to mind: 1. alternator isn't doing its job (does the battery light ever come on when you're driving?) 2. battery won't take/hold a charge 3. excessive parasitic draw on the battery with the car shut off

Load test - may have been faulty
The Load test - we did NOT rev the engine to 2,000; just let it idle - and with test applied - engine stalled
The counter guy may not have known what he's doing. I'm thinking the Parasite comment may be right Last weekend - the car worked each day, but the battery was dead after several days. I will comment - today - the car always required a jump - even after two 45 minute drive - with a jump in between. Thanks again for the suggestions.
