Electrical Specifications
800/1000 cc

NOTE: The ignition system is a Normally Open Ignition (NOI).
* Main harness plugged in

NOTE: To test the coolant temperature sensor, see Section 5.
Peak Voltage Tests were made at room temperature with the MaxiClips (p/n 0744-041), Fluke Model 77 Multime-
ter (p/n 0644-559) set to the DC Volt scale, and the Peak Voltage Reading Adapter (p/n 0644-307). Also, the main
harness connectors must be unplugged (except on the primary coil and voltage 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.
