5. CHARGING CIRCUIT 5. CHARGING CIRCUIT 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-01). The current also flows from alternator to each electrical component and controller through the fuse box.
