*NO LEDs are lit = Battery has LESS THAN 11.2 VOLTS (see page 13)
**NO LEDs are lit = Battery has LESS THAN 22.4 VOLTS (see page 13)
***NO LEDs are lit = Battery has LESS THAN 33.6 VOLTS (see page 13)
****NO LEDs are lit = Battery has LESS THAN 44.8 VOLTS (see page 13)
All (4) LEDs are lit, if alternator output is high enough to charge battery, when required.
