How to Troubleshoot a Tiny-Tach
A tachometer is a unit that measures the RPM (revs per minute) of a particular machine; one particular model of this type of machine is the Tiny-Tach, by the Design Technology company. A Tiny-Tach can be easily attached to several different types of units -- assuming that it is in proper working order. Issues such as wrongly attached antenna wiring, a dead battery or a product that is not advanced enough for the machine it is attempting to provide a reading for could potentially trip you up, but with the correct know-how you should be able to get your Tiny-Tach back in normal working order. Does this Spark an idea?

Ensure that the Tiny-Tach has been installed correctly if it is receiving erroneous signals. The antenna wire of the Tiny-Tach must be be wrapped around the sparkplug wire of the unit to pick up the signal. If this is not apparent then that is the cause of the malfunction.

Ensure you are using the correct battery and make sure it has sufficient life to power the Tiny-Tach. A 3-volt lithium battery powers the gas Tiny-Tachs and the battery should be replaced every five years. If there is no display on the unit then it could indicate the battery is dead and must be replaced.

Consider upgrading your product if you are installing onto a multi-cylinder engine and are receiving excess noise. You may require a filter to cut out extreme electronic noise, which must be ordered, custom built, from the company.

Troubleshoot problems with wiring length by sending the Tiny-Tach back to Design Technology for adjustment. This adjustment should not be seen as a DIY job.
