I have a Yamaha tach/hourmeter that I had on an old machine and now that I am getting a new ride I want to use the same device. The problem is that I don't know how to reset the device. Any thoughts or am I going to have to spend another $30 for another one? It seems silly to have to spend the money again but if I have to I will - it is very handy. Any tips? Thanks!

 

If it is battery operated pull the batteries out of it. If its mechanical, you might be outta luck.
