Front tach inop
I have a 1966 337A and the front tach has gone inop. Tried switching front and rear leads on the back of the tach and there is nothing wrong with the instrument. My Service Manual shows a tach pick-up coil on the bottom of the right magneto. But the only thing on the bottom of my right magneto (both magnetos actually) is a Magneto Filter Capacitor and the one on the right mag seems to be connected to the tach. I have continuity in the lead from the tach to the filter capacitor. Not sure where to go from here. Anyone have experience with this setup?
