Starting System

The starting system consists of the following components.

2. Starter Solenoid

3. Neutral Start Switch

4. Starter Motor

5. Ignition Switch

The function of the starting system is to crank the engine.

The battery supplies electrical energy to crank the starter

motor. When the ignition switch is turned to "Start" position,

the starter solenoid is activated and completes the starting

circuit between the battery and starter.

The starter motor may be damaged if operated contin-

uously. DO NOT operate continuously for more than 30

seconds. Allow a 2 minute cooling period between

starting attempts.

Before beginning the starting circuit troubleshooting flow

chart, following, check first for the following conditions:

1. Make sure that battery is fully charged.
