Rayesyth Ignition Coil and Voltage Rectifier Kit for Onan P-Series (P216G/P218G/P220G) — Heavy‑Duty Repair Pair

Complete replacement kit combining the Rayesyth ignition coil (166-0761) and voltage rectifier (191-2227) engineered for Onan P-Series small engines.

This two-part kit supplies both the ignition coil and voltage rectifier designed to match common Onan P216G, P218G and P220G engine applications found on John Deere and other lawn and power equipment. Sold together to simplify repairs, the components cross-reference multiple OEM numbers so you can replace a degraded coil and a failing rectifier in one order. The parts are manufactured for outdoor small-engine use and built to withstand the vibration, temperature swings, and intermittent storage typical of lawn tractors, generators, and small stationary engines.

Which machines and engine models will these parts fit?

These Rayesyth parts are specified for Onan P-Series engines used in various garden and utility equipment. Verify your engine model and part numbers before ordering to ensure compatibility.

• Fits Onan P216G, P218G, P220G engines commonly installed in John Deere machines.
• Compatible with multiple points-model engine codes such as BF, BFA, BG, BGA, BGE, B43E, B43G, B43M, B48G.
• Includes cross-reference coverage for older OEM numbers listed in the product features.
• Intended for 16–20 HP P-Series Onan engines where these part numbers are specified.

How will replacing both the coil and rectifier help my engine performance?

Replacing the ignition coil restores consistent spark delivery, while the rectifier ensures the charging system maintains proper voltage. Together, they address common failure modes that cause hard starting, intermittent spark, and battery drain.

• Ignition coil renewal reduces misfires and starting issues caused by coil wear.
• Rectifier replacement stabilizes battery charging and prevents constant drain.
• Buying both parts at once avoids repeated downtime sourcing separate components.
• Heavy-duty construction suits seasonal outdoor usage and storage cycles.

What should I check before installation to make sure these parts are correct?

Confirm the engine model, OEM cross-reference numbers, and physical connector types before ordering. A quick visual match and measurement of mounting points will prevent fitment problems during installation.

• Match engine code (P216G, P218G, P220G) stamped on your engine housing.
• Compare OEM cross-reference numbers like 166-0761, 191-2227, or listed equivalents.
• Check electrical connector styles and mounting hole spacing against the old parts.
• Inspect wiring harness and coil lead lengths to ensure compatibility.

What are the durable and environmental design features of these components?

The kit is built for the demands of outdoor small engines with materials and ratings that tolerate vibration, moisture exposure, and seasonal temperature changes. These design choices extend field service life in lawn and generator applications where parts may sit unused for long periods.

• Sealed coil and rectifier housings resist moisture and contamination.
• Vibration-resistant mounts and internal construction for small-engine duty cycles.
• Temperature-tolerant materials handle hot running and cold storage conditions.
• Electrical connections sized for reliable charging and ignition performance.

Who is this for: This Rayesyth ignition coil and voltage rectifier kit is intended for DIY mechanics, maintenance technicians, and owners of John Deere and other lawn or utility equipment powered by Onan P-Series engines who want a single-order replacement for ignition and charging components. It’s useful when troubleshooting hard starts, intermittent spark, or battery drain and for preventative maintenance on aging small engines. Always confirm model and cross-reference numbers to ensure a proper fit before installing.
