Charge Lamp/Indicator: Description and Operation
The red charge warning lamp will illuminate if either the voltage is too low (below 10.5 V) or too high (above 15.5 V). In addition, the generator
provides a low signal to the instrument pack (pin 9, 48-way connector) when battery charging is unsatisfactory.
