What It Is

The Runleader Hour Tach Meter is a waterproof, backlit digital hour meter that tracks engine runtime, displays RPM, and includes programmable maintenance reminders. It’s designed for zero-turn mowers, ATVs, generators, marine engines, and any small engine equipment where monitoring hours and service intervals is critical.

Fitment & Compatibility

• Mounting: Universal fit – attaches to any flat surface via included double-sided tape or screws. Works on gas or diesel engines with a spark plug wire (gas) or alternator/coil signal (diesel).
• Wiring: Requires a 12V or 24V DC power source (connects to battery, ignition switch, or accessory terminal). Not for AC-only systems.
• RPM Sensing: Picks up RPM from spark plug inductive pickup (gas) or alternator waveform (diesel). Confirm your engine produces a clean signal – some small single-cylinder engines may need fine-tuning of the pickup position.
• Physical Size: 2.3” x 1.5” x 0.8” – fits most dash panels or handlebars. Check clearance if mounting on a tight ZTR console.

Key Things to Know

• Waterproof but not submersible: IP65 rated – resists rain and hose spray, but don’t pressure-wash directly or submerge.
• Replaceable battery (CR2032): Retains hours and settings even when main power is off. Battery lasts 2-3 years under normal use.
• Installation is moderate: You’ll need basic wiring skills – splice into ignition-switched power and wrap the inductive pickup around the spark plug wire (not the plug boot). No special tools required.
• RPM alert can be annoying: The red button triggers a programmable RPM warning (e.g., for over-rev). If you don’t need it, leave it disabled to avoid false alarms.

Should You Buy It

Buy this if you want a reliable, low-cost hour meter with maintenance reminders and RPM display for a ZTR mower, ATV, or generator, and you’re comfortable with a simple wiring job. Skip it if you need a plug-and-play OEM replacement for a specific brand’s factory harness or if you want a model with Bluetooth/app connectivity.
