results when using tape, be
sure to clean off any dirt,
grease and oil from the

as denatured alcohol.

Find a suitable route to run

Connecting the Wires

™

CAUTION - KEEP
WIRE CLEAR OF

EXTREMELY HOT
ENGINE PARTS SUCH
AS THE MUFFLER, AND
MOVING PARTS.

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.)

WARRANTY: Design Technology, Inc. warrants that for a period of one year from time of purchase it will repair or replace the TINY-TACHTM,
without charge, if it fails to function properly due to a defect in workmanship or materials in the instrument. Damage caused to the wires
and cables by improper care or use is expressly excluded from this warranty. Used TINY-TACH
reseller will be warranted at the discretion of Design Technology, Inc.

In order to assure that you receive the correct model for your application, we request that you please enclose a short note describing the
problem, the type of engine and number of cylinders.
