W110 190Cmalternator Brushes

I am sure my alternator brushes are bad. Can't seem to find a source for new brushes or a new alternator. Any advice? This is a 1963 190C.

pull it out and get a rebuilt from Bosch about $95

Has your car been converted from a generator?

How do you know they are bad?

These cars originally came with generators. A previous owner upgraded to an alternator at some point. Check the alternator amperage rating. I suspect 35 amps.

Disconnect the battery negative lead first. Remove the alternator, and match mark the case, you can use a punch or a felt tip pen or marker. Take the case apart and the brushes are inside. The brush leads must me soldered.

To reassemble, notice a small hole in the back cover. Use a small pin to keep the brushes retracted and reassemble the case. Remove the pin after reassembly.

Brushes are available, check the EPC for a 250S/SE, 108.012, 108.014, and the brushed are displayed, look for the electrical or charging system page.

You can also upgrade to a more recent alternator with the replaceable brush - regulator which are more common. No external regulator is required.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant
