The carbon brushes are possible culprits. The brushes are easy enough to inspect. If you suspect them, check them. But...

The problem might be an open diode in the alternator. Or a bad ground. Or resistive power cable to the battery. Or weak cell in the battery. Or...

You see what I mean? You need to check some things. Start with the battery. Load test the battery. If it falls too rapidly and recovers too slowly, that is a problem. Google "load testing battery".

If you see this happen only when the fans come on, there just might be a problem with a fan motor.
