PRO BAT GY6 6-Coil 5-Wire Stator Magneto for 50cc–150cc Engines, High-Output AC Charging

The PRO BAT 6 Coil 5 Wire GY6 Stator Magneto is a direct-fit AC alternator stator designed to replace worn charging and ignition stators on GY6 50cc, 125cc and 150cc engines.

This high-output stator is built for scooters, ATVs, go-karts and small UTVs that use the common GY6 series engines. It provides alternating current for lighting and accessories and interfaces with engines that use a 5-wire female plug and 6-coil configuration. Engineered as a replacement part, the unit accepts standard mounting and plug connections used across many popular manufacturers, making it a practical spare or repair component for roadside fixes and scheduled maintenance.

How will this stator restore my vehicle's charging and ignition functions?

Installing this stator brings back AC output to recharge batteries, power lights and feed ignition systems that rely on alternator current. It matches the GY6 6-coil layout and 5-wire connector, so it plugs into the wiring harness used by many aftermarket and OEM setups. Using a correct-fit stator prevents intermittent charging and dim lighting caused by damaged windings or corroded connections.

• 6 coil design for stable AC output
• 5-wire female plug matches factory harnesses
• Designed for ignition and accessory power on GY6 engines
• Replaces failing or burnt stator windings

What engine models and brands is this compatible with?

This stator is made for common GY6-series engines including 139QMA, 139QMB, 152QMI and 157QMJ found in 50cc, 125cc and 150cc platforms. It fits many popular Chinese and international small-engine brands that built models around the GY6 footprint. Always compare plug and mounting measurements to your existing stator to confirm compatibility.

• Works with scooters, mopeds, ATVs, go-karts and dune buggies
• Compatible brands: Zongshen, Lifan, JCL, Buyang, Loncin, Taotao and more
• Intended for CVT GY6 engines in 50cc–150cc range
• Double-check plug pinout and mounting hole spacing before install

What are the physical specs and what’s included in the package?

The stator measures for easy verification: overall diameter, inner mounting bore and center-to-center hole spacing match common GY6 replacements. Knowing these dimensions ensures the part will seat correctly in the crankcase and align with the flywheel magnets. The package supplies the stator and basic mounting hardware for a fast swap.

• Overall diameter approx. 83 mm (3.26")
• Inner diameter about 29 mm (1.14")
• Mounting holes center-to-center roughly 42 mm (1.65")
• Includes 1 stator and 2 mounting screws

How difficult is installation and what should I check after fitting?

Installation requires basic mechanical skill: remove the crankcase cover, unbolt the old stator, disconnect the wiring, and secure the replacement with supplied screws. After reassembly, verify plug seating and test lighting and charging output at idle and higher RPM. If unsure, consult a repair manual or a qualified mechanic to avoid damage to the new stator or surrounding components.

• Requires crankcase access and standard hand tools
• Test charging volts and lighting function after install
• Ensure connector is fully seated and wiring insulated
• Refer to torque specs and service manual for your model

Who is this for: Owners, mechanics and fleet operators who service scooters, mopeds, ATVs, go-karts or dune buggies powered by GY6 50cc–150cc engines and need a reliable replacement stator. It’s a practical choice for anyone restoring charging performance or replacing a failed alternator component on common GY6-based platforms. If you want a direct-fit, AC-output stator with standard mounting and a 5-wire harness, this PRO BAT unit is built for routine repairs and preventative parts inventory.
