3. CHARGING CIRCUIT (#1001 and up, TIER II)

When the starter is activated and the engine is started, the operator releases the key switch to the ON
position.
Charging current generated by operating alternator flows into the battery through the battery relay
(CR-1).
The current also flows from alternator to each electrical component and controller through the fuse box.
