FAQ 

Q: Does constant charging warning light always mean bad alternator?
A: Not necessarily. Check slipping belt, loose connector and aged battery before testing alternator output.

Q: Can I only replace carbon brushes if they are worn short?
A: It is acceptable only when bearing, rectifier and regulator are in good condition. Full assembly replacement is recommended for aged engines to avoid repeated failure.

Q: What damage will high charging voltage cause?
A: Overvoltage accelerates battery swelling and aging, and burns lamps, relays and ECU.

Q: What risk exists if battery negative is not disconnected during removal?
A: Short circuit may happen, blow alternator diodes, fuses and electronic control units.
