I have a Kioti Mechron 22000 that will not start. I have changed the 60 AMP fuse, every relay, two ignition switches, two display units, cleaned every electrical connector, changed the battery, and it will still not start. When the key is in the start position the starter works and the engine rotates, but there the instrument panel does not light up showing charge, glow plug heater indication etc. Any ideas? Please help.
