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.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit fix my engine that won’t start or stalls?\u003c\/h3\u003e\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaces worn coil 166-0761 (and cross-references listed).\u003c\/li\u003e\n  \u003cli\u003eRestores consistent high-voltage output to spark plug(s).\u003c\/li\u003e\n  \u003cli\u003eWorks alongside a functioning rectifier to stop intermittent stall issues tied to unstable voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the voltage rectifier stop my battery from draining?\u003c\/h3\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaces rectifier part 191-2227 (with listed cross references).\u003c\/li\u003e\n  \u003cli\u003eConverts alternator output to stable DC for battery charging.\u003c\/li\u003e\n  \u003cli\u003ePrevents leakage that can drain the battery during operation or storage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich engines and models are compatible with these parts?\u003c\/h3\u003e\n\u003cp\u003eThis kit fits John Deere equipment using Onan P-Series engines—specifically P216G, P218G and P220G—and a wide range of points-style models.
