			===Installation and Sensor Gap===
			When installing the sensor, ensure there is a minimal gap between the sensor and trigger wheel - 1mm (or credit card thickness) or less. This ensures a strong and reliable signal for accurate timing.

	Note that there are two types of older Smiths tachometers: RVI - current sensing, and RVC - voltage sensing. These letters, and numbers indicating exactly which variant you have, are printed in small white lettering on the bottom of the face of the tachometer. RVI type tachometers work by routing the coil +ve supply wire through an inductive loop of wire inside the tachometer, and are not compatible with the MJLJ tach out signal or the tach out signal from the EDIS control module. If you have an RVI type ~~tachomoter~~, you can try routing the power wire for the EDIS coil pack only through the tachometer so the induction windings in the tach can pick up the spark firing events like the OEM system. This has been tested on a 4 cylinder British car with an OEM RVI tach and it gave excellent results. Other options are you replace the tach with a different type, have an add-on circuit board added inside (or build one yourself, see http://www.dinoplex.org/tachoconversion for a start), or replace all the inside working parts with those from a newer tachometer ie retain the original face, but change everything else. For that approach you need a donor which has the same angular swing per 1000rpm, as the Smiths gauge.
