Tach Generator Cessna 340
My RPM gauge does not show anything at startup on right engine. Then at
runup it comes to life at high RPM. Then after that it works fine. It wobbles a bit sometimes in the air. My take is that my tach generator is the problem. Any other ideas. Also do you know where to get a replacement unit or overhaul?

Are you sure that it even has a tach generator? If it does, it could be
either that or the guage. Try swapping things side to side until the problem switches sides. Mike MU-2 wrote in message oups.com... My RPM gauge does not show anything at startup on right engine.

Because of the location of the tach generator it is susceptible to getting oil into the cannon plug connector. The first thing I would try is to undo this connector, thoroughly clean and re-connect. If that doesn't help you can try swapping sides as Mike suggests to determine if it is the generator or the tach itself. Allen
