Tach question

[piemma]

My tach on my new boat stopped working, frozen at 1500 RPMs. How do I know whether it's the tach gauge or the tach head on the motor?
New tach is around $100 with tax. I have no idea what a tach head would cost. It's a Faria gauge and a Yami 115 4 stroke.

I don't want to buy a gauge and find out it doesn't solve the problem. Usually you cannot bring back electronics once you open the package and try them.

Be sure the engine is charging.. if the rectifier is bad, the tach will not work either...

If it's the tach you might want to contact Faria.

Yep it lights up and I know the alternator is working because the batteries stay charged.
