20A Alternator Kit - Harley DavidsonCaracteristicas: Kits include stator, rotor, black rectifying voltage regulator and mounting hardware Made in the U. S. A.

If you draw too many amps through a switch or wire, it will heat up and may burn. Fuses and breakers are sized to protect wiring and switches. DO NOT CHANGE 30A MAIN BREAKER TO A 50A BREAKER.
