Good morning from Central Florida. My 1999 Yamaha, 90hp 2 stroke, it is a "C" model without oil tank, has a problem where the tach will drop to zero while the engine is running, it happens at all throttle speeds. If I fiddle with the ignition switch the tach will work for a couple seconds then quit. Also, when the tach quits, if I activate the trim/tilt switch the tach will also start working for a few seconds. All other gauges, Fuel, ammeter, continue working. This problem started out a while ago as very very intermittant and has progressed to being constant. I don't mind spending the money for a new ignition switch if that would solve the problem.
Any advise or comments are appreciated.
