FAQ:

Q: What does a rectifier do to a motorcycle?

A: There are primary two functions that are performed by the Rectifier on the bike: It converts the AC into the DC. It is also attached to a voltage regulator that regulates the power generated by the AC generator, or we can say the Alternator.

Q: Where can I get a rectifier for my scooter?

A: Let the experts at Monster Scooter Parts help you identify the correct rectifier for your off-road vehicle or ATV. Just have the old rectifier available for reference before calling customer service at 1-800-798-0325.

Q: When to replace a rectifier on an ATV?

A: Off-road rectifiers and ATV rectifiers should be replaced when damaged or defective to prevent damage to your more expensive electrical components. Let the experts at Monster Scooter Parts help you identify the correct rectifier for your off-road vehicle or ATV.

Q: What kind of voltage regulator does a bicycle use?

A: 1) 2-pin Regulator: This type may be found on some small bicycles which do not have battery and only have Head Lamp & Tail Lamp. Since the incandescent bulbs work well on AC voltage, there is no rectifier section in this type of regulator. The circuit inside the unit regulates the AC voltage coming from the generator to 13.5 – 14 VAC for the bulbs.
