[C320-list] New Tachometer

[John Frost]

Immediately after I did some puttering around the transmission of my 2007
Yanmar 3YM30, the tachometer stopped working.
As I put transmission in and out of gear it works momentarily. I assume I
have a loose wire on the engine pickup?
 I have read that the pickup comes from the alternator. Others say a
magnetic sensor by the flywheel (which is where I was working). Does anybody
know?

I second Gary's suggestion. Worked for me. I did this a year ago and 
it's still working great!
