Adding an hour meter+

[Dave Carney]

I know some units came with one but mine (4390-1) did not. I've been keeping hour estimates in a journal, which is kinda low rent. How hard would it be to add one? what wires would I tap? Can I buy the one generac uses? Thanks!

That is a link to our "Tiny Tachs"

They are a sealed unit, so you can't replace the battery. They last around 7 years, and they take about 5 minutes to install.

It monitors spark pulse by wrapping a monitoring wirearound the spark plug wire.

When the engine is running, it starts counting, minutes and hours. It also works as a tachometer, but it is NOT accurate enough to use during engine diagnosis.

I will do a "how to" install with one of these because we sell a ton of them. I believe we have around 1200 in stock.

Thanks!

Ordered, thanks.

Ordered, thanks.

When it arrives, you will simply have to wrap the red wire around the back spark plug on your v-twin, and you will see a little ground wire. I would suggest putting that on one of the back valve cover bolts. It is a 10mm bolt.
