Review on 🚗 ESUPPORT Car Tachometer Gauge Meter 2" 52mm Tacho RPM Pointer with Blue LED Light by Anthony Daniels

Had to sift through reviews to find out how to adjust the number of cylinders. This is the manufacturer's responsibility, not the buyer's. Little engine tip: use a diode and activate it from the light generator output. At B&S, most of them use four poles. You get a pulsating direct current for a half cycle. It doesn't matter if they are triggered by a rising or falling edge - at some point it will reset to zero. Set for 8 cylinders.
