Electrical

Specifications

(500 cc Models)

NOTE: The ignition system is a Normally Open Ignition (NOI).

* Harness plugged in

Peak Voltage Tests were made at room temperature with the MaxiClips (p/n 0744-041), Fluke Model 73 Multime-

ter (p/n 0644-191) 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/CCU 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, espe-
cially those using pacemakers, must avoid contact with all electrical connections when pulling the recoil starter
rope or after the engine has been started.
