I wore my first Tiny Tach out after more than fifteen years. The battery eventually died and is not replacable. I called Tiny Tach with a question and to order another one and darned if they didn't just send me a new one. Free.
When I put new electronic ignition wires on I had to fiddle with the number of windings wrapped around the new Taylor ThunderVolt 8.2 mm 40 oHm wires. These tires are shielded extremely well yet, at 40 oHms, offer practically no resistance. My old wires, also Taylor, were very old and putting new ones on made a world of difference. Radio clarity actually improved despite the OWT that resistance wires are necessary to prevent RF and EMI interference. This was such a clear reminder that ignition wires wear out - no matter how nice they may look on the outside - that I replaced the wires on the car at the same time. The wires on my daily driver - a 1982 Suzuki GS850G - are 34 years old and have 40K on them and the bike still starts instantaneously so maybe bike wires are made better - probably solid core copper. It's the ferrite or carbon core wires that break down over time. Shielding also breaks down over time so despite the fact it runs like a Swiss watch the Suzuki could probably use some new wires. So . . . back to TT. Initially I complained to the group about the trouble I was having getting the tach to register reliably. Mark replied that he had had the same problem with TT and had given up on it (if I recall correctly). It took a bit of experimentation (not all that much overall) but I finally got the winding correct and TT has been operating fine ever since. I made no cuts in my Taylor wire shielding - the only variable was the number of windings of the TT lead around the plug wire. Make sure you've got a good ground with the other lead. Keep playing with the windings and you'll get it working. I am in awe of Tiny Tach - both of their reliability and customer service.
