Thanks in advance for any help in solving this mystery. A few weeks ago, my speedometer started going to zero and the digital (LCD) odometer goes blank whenever the clutch clutch lever is pulled in far enough to open the clutch interlock switch. I first noticed it when shifting and thought voltage was dropping excessively when the engine RPMs dropped, but there are no other indications of low voltage. It seems to be a direct result of the clutch interlock switch opening.
