Quick Answer
Turn off engine before installation. Verify meter compatibility with ignition type. Mount unit securely to frame or panel. Wrap sensor wire four to five turns around spark plug lead. Route wire clear of exhaust heat and moving parts. Fasten wire using zip ties. Run engine to verify RPM and hour tracking operation.

How to Install an Hour Meter and Tachometer on a Spark-Ignition Engine
An engine without an hour meter or tachometer is maintained by guesswork. Calendar intervals ignore load, idle time, and duty cycle, and the result is either premature servicing or deferred maintenance that shortens engine life. This guide covers the engineering rationale for instrumenting an engine, the selection criteria for compatible meters, the electrical and thermal hazards of the work, and an installation procedure that produces a stable, accurate signal. It applies to generators, outboards, garden and utility machinery, compressors, pumps, small vehicles, and other spark-ignition platforms. Signal alternatives for compression-ignition engines are covered where they differ.
Why Track Engine Hours
Engine wear correlates with operating time and load, not with elapsed calendar time. A generator that sits idle for eleven months and runs for one has a very different wear profile from a unit running 8 hours daily. Manufacturer documentation for most small air-cooled gasoline engines specifies service in hours, and the typical intervals are listed below. Verify them against the service manual for the specific engine.
