CAUTION

KEEP WIRE CLEAR OF

EXTREMELY HOT ENGINE

PARTS SUCH AS THE

MUFFLER, AND MOVING

Wire damage (cuts or burns) will cause the wire to short and your TINY-TACHTM will stop working. Wire damage is not covered under warranty.

The RED WIRE should be slipped over an insulated section of the spark plug wire using about 3* turns. PLEASE BE CERTAIN YOU DO NOT WRAP THE RED WIRE TOO CLOSE TO THE SPARK PLUG THAT ENGINE VIBRATION WILL ALLOW IT TO COME INTO DIRECT CONTACT WITH THE METAL PORTION OF THE SPARK PLUG. Most engines

have a spark plug cap and will prevent this from happening. After the connections are made, any excess wire can be coiled up and taped to a convenient area.

* If the signal is not strong enough, you can add one wrap at a time until your signal is clear. The signal strength is controlled by the number of wraps (too many wraps will pick up electronic noise and give a faulty reading.)
