Conversation Between springer3 and KingEider

Springer3, Noted your expertise on the troubleshooting electron flow in the C2. Would value your opinion. The '90 C2 has a recently developed habit of displaying the alternator light when I activate the brake pedal at low speed or at a stop. Tapping the brake a high speed does not cause the problem. Braking with the E-Brake avoids the alt light illumination. Battery is 13.9 V at idle....no change when I step on the brake. Light goes off when I restart the car. Brake lights work fine, fresh rebuilt Bosch alternator, first electrical issue I have had. Any thoughts? Thanks, Frank
