I have a single engine FL 120 with a tach on the FB and one on the lower helm. Both worked fine last week. Now neither appears to be working. The hour meter on the lower helm tach is functioning. Not sure if that is any indicator of the tach connection or not.
I am not clear on what exactly is the connection for the tach on the back of the alternator, but it appears there is a single wire that leads to a connection in a silver box mounted on the engine room wall. I do not see any connection issues but really not sure what I need to check at the source. It would seem to me that with both tachs suddenly not functioning, the issue would be at the alternator but not sure where to go from there to figure out a next step.
The attached picture may or may not be any help.
Any assistance is greatly appreciated.
