models are equipped with a fully transistorized ignition system. This solid state system, unlike breaker point systems, provides a longer life for components and delivers a more efficient spark throughout the entire speed range of the engine. Ignition timing and advance are maintained without adjustment.

When the crankshaft-driven reluctor passes one of the pick-up coils, a pulse is generated within the pick-up coil. This pulse (electrical current) flows to the switching and distributing circuits in the ignitor unit. The ignitor unit is also controlled by the
sidestand relay and switch. When the sidestand is down, the ignition control unit is grounded through the sidestand relay. The engine cannot be started when the sidestand is down unless the transmission is in NEUTRAL.

The following schematic illustrates the Yamaha Virago XV920J Diagram.
