Question about 2001 Mercedes-Benz C-Class
Posted by Anonymous on
Clean the battery terminals well. Use a special di-electric between the clamps and the posts (nothing else as vaseline or other are insulators)
Make sure the belt is tight that turns the alternator. Make sure the alternator has a good ground (not greasy or oxidized). Make sure the engine block is grounded to the frame with a braided cable. Hopefully you replaced the voltage regulator when you changed the battery as is the custom of any trained mechanic.

This is normally a low voltage from the alternator condition. Hook a voltmeter to the battery and note the reading. Should be 11.6vdc to 12.2vdc. Start the car, after a minute or so it should be around 13 to 14 vdc., if not then the alternator may be bad

I had the same problem. I don't know if your solution is the same as mine, but mine was a problem with the electronics in the seat adjustments. It was going to cost me about $1,000.00 to replace these. I had the seats unplugged.

check voltage across battery with engine running and engine off ,check with a automotive multimeter as it may just be a faulty dial ,if voltage rises to 14.7 volts or there abouts with engine at 2000 rpm then all is fine ,if low then it could be a problem with the ECU as this controls the output on a newer car like this and if its not working correctly then its a expensive dealer job but the alternator can be converted back to battery sensed charging
