For safety reasons, the starter motor can only be operated when the automatic transmission is in Park or Neutral position; or if the car has a manual transmission, when the clutch pedal is depressed.

We have just bought a MkI 65 serial number SNY 519642, with 8466 hours on the clock. It has a dual clutch, diff-lock and has been recently painted (although it’s only a poor paint job, done by the previous owner). Overall condition of the tractor isn’t too bad and the bonnet is very good indeed, with no rust and no dents. It has recently had a new battery, starter motor, seat and water hoses, but it does still require quite a lot of mechanical repairs before it can be repainted. As you can see from the pictures, the safety start switch isn’t wired up, the whole wiring is a mess and the regulator box isn’t on its’ mountings.

Honda’s unique CBR600RR starter motor with a flat commutator is tested in exactly the same way. Honda does not recommend using emery paper on the commutator, nor is it recommended that the mica undercut be cleaned out.

When you turn the ignition key to the START position, the battery voltage goes through the starter control circuit and activates the starter solenoid, which in turn energizes the starter motor. At the same time, the starter solenoid pushes the starter gear forward to mesh it with the engine flywheel (flexplate in an automatic transmission). The flywheel is attached to the engine crankshaft. The starter motor spins, turning over the engine crankshaft allowing the engine to start.
