12 Vdc Charging System
Battery charging current is supplied by Controller. The battery charging circuit provides current to the battery until the proper charge level is attained (13.1 to 14.6 volts).
The alternator exciter field is controlled by the DSR. This initiates battery charging approximately 15 seconds after unit has output voltage.
Note The engine must run for approximately 120 seconds before
the battery charging circuit is energized.
