MEFI Fuel Injection
High Voltage Switch
The High Voltage Switch looks and more or less acts like a distributor. It distributes the high voltage from the coil to the spark plugs, it also contains the camshaft position sensor. The High Voltage Switch ignition system is used on our new MEFI 4 IAFM engines. This system features a camshaft driven distributor, an ignition control module, a crankshaft position sensor, a camshaft position sensor, and an ignition coil. The distributor has a composite base which incorporates the camshaft position vane switch and a rotary vane cup. The ECM takes the input signal from the cam and crank sensors, outputs an ignition control signal to the ignition control module, the IC module then triggers the coil.
