
NOTE: The ignition system is a Normally Open Ignition (NOI).
* Harness plugged in
Peak Voltage Tests were made with the Fluke Model 77 Multimeter (p/n 0644-559) set to the DC Volt scale and the
Peak Voltage Reading Adapter (p/n 0644-307) with the main harness connectors unplugged (except on the primary
coil test), spark plugs removed and grounded, and by pulling the recoil starter rope briskly.

NOTE: Lighting coil output is unregulated voltage.
