Battery Discharge Protection Relay: Description and Operation
The battery saver is activated when the
GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil, activating the relay, for a period of
10 minutes with the interior lamp (headlamp) switch in the off position, or a maximum period of
45 minutes with the interior lamp (headlamp) switch in the on position, provided that the GEM does not receive any other input signals within the time-out period. The activated battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM disconnects ground from the battery saver relay coil disabling the demand lamp circuit.
