Review on 🔍 Magicalmai Inductive Hour Meter: Waterproof Hr Meter for Gas Engine Generator/Lawn Mower/Pressure Washer/ATV/Outboard Motor/Dirt Bike/Motorcycle - Yellow by David Golden

Bought a pair of these to use on 2 small inverter generators for recommended oil change maintenance. I thought they did a great job so I bought a third one and installed it on another generator. A sensor cable is supplied which needs to be wrapped and secured around the spark plug wire and the other end inserted into the groove on the back of the generator. Meter. I then used the screws provided to attach the gauge to the orange generator by threading the wire through the hole I had drilled in the generator housing behind the gauge. The meter on the 3rd block (yellow) was attached to the gas tank with double-sided foam tape. All devices are supplied with the meter. After almost 400 hours of operation I am very satisfied.
