Good afternoon, I hope this email finds you doing well. I have a question regarding my speedometer and tachometer. At Idle the speedo will bounce from one side of the dial to the other. immediately following the tach will do the same. The digital portion of the tach flashes "test". I was wondering if you might have any knowledge regarding this symptom?
Thank you for any insight that you may provide.
perhaps a little history with my coach may help.. I recently purchased my coach from the second owners. However they parked and did not use the coach for many years. It certainly needs some attention but I believe it to be a diamond in the rough.
