Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Recheck listed specs such as Match by 4-pin connector and 12V DC system, Match by 4-pin plug and charging system type, Match by 4-pin plug, size, and original part. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
Fixed my battery discharge issue and haven't had any problems with it.
right part fast ship thanks
works perfect thanx
Fast delivery. Looks as described. Functionality is unknown. It didn't work at least not for my moped. 50 - 125cc. Note. I have a 5 pin AC with led lights. Double check! And anyone who has LED LIGHTS will NEED Alternate Current!! Not DC! Thus meaning "Direct Current' for wattage ohm regulator. It was explained to me by an actual licensed motorcycle/ moped mechanic. That if you turn on the ignition? The best way to check your style needed and lights are automatically on without turning over the bike running? Then the product model it's DC - not AC! Now?Alternate Current part if the bike must be running for headlight and running lights to work properly. Turns on! AC ! Plus you will want check if yours is 5 pin or 4 pin. [ OR NUMBER OF WIRES. Otherwise, it will not work! Hopefully this is helpful to someone else? Mahalo!
So far, so good. Lasted longer than the cheaper ones and still going.
