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.
