Alternator Accessories

Upgrading to a high-output alternator often needs more than the alternator itself. This collection includes Balmar AltMount serpentine pulley conversion kits and belts, Balmar alternator temperature sensors, the Xantrex alternator battery temperature sensor, Sterling remote controls for alternator-to-battery chargers, the AP12D 12-24V alternator surge protector, Powerline pulleys for 23HD and 24HD series alternators, regulators and wire harnesses.

How to choose alternator accessories

• Belt drive: high-output alternators may need a serpentine belt conversion to avoid belt slip and dust.
• Temperature sensing: sensors let the regulator reduce output before the alternator overheats.
• Protection: a surge protector guards diodes if the battery switch is turned off while charging.
• Fit: match pulley and harness part numbers to your alternator series.

Do I need a serpentine pulley kit?

Alternators above about 100A often benefit from a serpentine belt. Read the alternator and regulator guide.
