Rayesyth Ignition Coil & Voltage Rectifier Kit for Onan P216G–P220G (Restores Spark & Charging)

Rayesyth's kit replaces the Onan ignition coil 166-0761 and voltage rectifier 191-2227 to restore spark reliability and charging performance on compatible John Deere/Onan small engines.

This two-piece replacement bundle is built for owners of John Deere machines and other equipment powered by Onan P-Series engines (P216G, P218G, P220G). The kit groups the ignition coil and rectifier into one purchase so you can address both lost spark and charging problems at once. Each component is manufactured for outdoor use and engineered to tolerate vibration, temperature swings, and seasonal storage that lawn tractors, generators, and similar small engines experience.

How will this kit fix my engine that won’t start or stalls?

If the engine has intermittent spark, hard starting, or stalls mid-season, the ignition coil is often the culprit—its internal windings degrade with heat and moisture. Replacing the coil restores consistent spark timing while the rectifier ensures the electrical system provides stable voltage to the battery and ignition circuit.

• Replaces worn coil 166-0761 (and cross-references listed).
• Restores consistent high-voltage output to spark plug(s).
• Works alongside a functioning rectifier to stop intermittent stall issues tied to unstable voltage.

Will the voltage rectifier stop my battery from draining?

A failing rectifier can allow AC leakage or fail to properly convert alternator output, causing slow or continuous battery drain. Installing the included 191-2227 rectifier restores proper DC regulation and prevents overcharging or constant drain that shortens battery life.

• Replaces rectifier part 191-2227 (with listed cross references).
• Converts alternator output to stable DC for battery charging.
• Prevents leakage that can drain the battery during operation or storage.

Which engines and models are compatible with these parts?

This kit fits John Deere equipment using Onan P-Series engines—specifically P216G, P218G and P220G—and a wide range of points-style models. Always confirm original part numbers and fitment before ordering to ensure compatibility with your machine.

• Ignition coil fits models such as BF, BFA, BG, BGA, BGE, B43E/G/M, B48G, CCK/CCKA/CCKB, NHA/NHB/NHC/NHE/NHP, N52M, and similar points engines.
• Rectifier fits Onan P-Series 16–20 HP variants (P216G–P220G).
• Check original stamped or service manual part numbers to verify match.

What durability and environmental protections do these replacement parts offer?

Both components are designed for heavy-duty outdoor use, with materials and assemblies selected to resist vibration, moisture, and seasonal storage stresses common to lawn and power equipment. That helps reduce premature failure from rust, heat cycling, or rough terrain operation.

• Vibration-resistant mounting and terminals for stable electrical contact.
• Sealed or protected windings and electronic components against moisture ingress.
• Temperature-tolerant materials suited to seasonal extremes and long idle periods.

Who this kit is for: This Rayesyth ignition coil and voltage rectifier pair is targeted at DIY mechanics, small-engine technicians, and equipment owners who need a straightforward repair solution for Onan P-Series engines used in John Deere mowers, backup generators, and similar machines. Choose this kit if you want both ignition and charging components replaced together to save time sourcing parts separately. Always confirm fitment with your machine's service data before purchase.
