--------------- END SUPPLEMENT ---------------
A new family of digital tachometers is available. The new tachomoters are self-powered by either a flywheel sensor or tachometer generator. Two of the tachometers have a rotary switch on the tachometer to be programmed to work with different flywheels (number of teeth). Some of the former tachometers used programming boards attached to the back of the tachometer.
The chart identifies the new and former tachometers their type.
NOTE: 9X3405 Sealing Plug Kit is available to seal the hole over the selector switch on 9X1116 and 9X1117 Tachometers.
