Electrical Specifications
* Harness plugged in
The main harness connectors must be unplugged (except on the primary coil and regulator/rectifier tests), the spark
plugs removed and grounded, and by pulling the recoil starter rope briskly.
NOTE: Lighting coil output is unregulated voltage.

! WARNING
Most voltages generated by the ignition system are sufficient to interrupt pacemakers! All technicians, especially
those using pacemakers, must avoid contact with all electrical connections when pulling the recoil starter rope or
after the engine has been started.
