Easyfit Tachometer Repair Kit Fitting Instructions
The Easyfit Tacho repair kits will repair three different types of Smiths / Jaeger tachometer - see below to choose the correct fitting instructions for your tachometer. There is a separate set of vehicle installation instructions which applies to all three tachometer types.
RV type - These have the letters "RV" marked in small lettering on the dial. They were originally driven from a Tacho Generator on the vehicle. Once the repair kit is fitted the tachometer will be driven directly from the ignition coil with no need for a tacho generator,
RVI Gen 1 Type - These have the lettering "RVI" marked on the dial and are driven from the ignition coil current. The ignition coil feed wire is looped through a transformer on the back of the case.
RVI Gen2 Type - These also have "RVI" marked on the dial. They are driven from the ignition coil current but the connection is via two bullet connectors on the back of the case.
