I have a c600he approx 1998. I have bought the mower recently and the light on the dash was lighting up to show the deck position and headlights were working. I have replaced the drive belts, starter solenoid removed the deck and replaced bearings and generally gave the mower and good tidy up. I have come to use now and everything works deck lowers and raised etc but I have lost the lights which show me the deck height on the dash. The headlights have also stopped working (not sure if related) any help to resolve this would be appreciated.
