Ignition Switch
Description
Purpose – to crank the engine. The battery supplies electricity to activate the starter mo-
tor. When the ignition switch is turned to the “START” position, the starter solenoid is ener-
gized and completes the starter circuit between the battery and starter.
The neutral start switch opens the starter circuit when the shift control lever is not in neu-
tral thus preventing accidental starting when the engine is in gear.
CAUTION
The starter motor may be damaged if operated continuously. DO NOT operate
continuously for more than 30 seconds. Allow a 2 minute cooling period between
starting attempts.
