Had an interesting one last weekend. After having been run for a short while I parked the machine. About an hour later I started it up again to move it and did not get any indications on the instrument panel at all -- no gas gauge, no tach needle routine, no warm up light. I put the machine into reverse and backed it up -- no backup beeper. Put it back into forward and moved the machine 15 feet to park it and all of a sudden all the instruments lit up, the warmup light was flashing and when I tried the reverse the beeper worked again. I haven't looked at the schematic yet but it's likely a relay contact that didn't make connection, probably the same circuit that keeps the headlights off while you're cranking it.
