Trouble-shooting tach, 1998 Ocean Pro 150

[btravlin2]

Howdy......where to now? It just decided to stop: not twitching, nothing at any speed. I've got 12.8v across the battery with and w/o the key, 13.8 at idle, and 14.2 revved. All steady voltages.

Mine is a plug on the back so I have no terminals to clean. I've removed the plug and put it back in a couple times. I don't have a pulse switch.

I'm hoping it's just the tach itself. What should I test next before I replace it?

Thanks in advance.....

See if you have any ac voltage on the gray wire at the tach when it's running. Best checked with a multimeter and a DVA adapter.
