HPM Powersports hour meter.
Hour meters work in any engine with a spark plug. They have internal batteries and are very easy to install. Simply wrap the wire around a spark plug ignition wire and run the wire up to your meter. No on/off switches, no batteries to change, just simply adds time when it senses ignition.
These are great to use to keep track of service intervals, keep track of new engine builds, keep track of running hours on small or large equipment and many other uses.
