Product details
Installing a tachometer on a diesel engine has always been tricky due to the lack of an ignition system. Traditional solutions were often complex and time-consuming. But with AutoMeter's Diesel Tach Adapter, it's never been easier or more affordable. This innovative device uses a simple inductive pickup that attaches to the outside of your alternator. Calibration is a breeze with the included push-button module, allowing you to drive any AutoMeter tachometer or RPM activated device effortlessly. Designed to work with most engines equipped with a crank-driven alternator, it's not just for diesel engines—it’s a versatile solution for a wide range of applications.
