T1A9-X Tach Mag Pickup

Our TSO’d tach mag pickups are available for slick(T1A9-1) and Bendix(T1A9-2)

Lighting Coil

UMA Lighting Coil tachometers are designed to connected to the positive going output of the Lighting coil. Signal voltage of 3 volts peak or greater is required (600V Peak Max).

Ignition Coil

These tachometers are desiged for use in a traditional point/condenser automotive type of ignition system. The input lead of the tachometer is connected to the negative side of the coil.

Magneto P-Lead

UMA P-Lead Tachometers are designed to work with Slick brand magnetos. They are not guaranteed to work with Bendix brand magnetos. To facilitate a “Mag Check”, we recommend that a switch be installed to switch the input of the tachometer between the two magnetos. Installation instructions for OLD TachometerInstallation instructions for DB9 (new) TachometerInstallation instructions for two Tachometers (Front & Rear).
