I would verify the wiring with this diagram.

Do your lights work properly, if not the voltage requlator is bad.

Greg,
The tach runs off of the lighting circuit. I'll shoot a picture of the all the connectings later today.

greg,
Here is a picture of the tach wiring on my cyclone. There is a double pig-tail connector in the back of the dash consisting of a yellow wire and a black wire. The yellow wire from the tach plugs into the yellow of the connector and the red wire from the tach plugs into the black wire of the connector.
