Normal Operation
The instrument cluster energizes the battery saver relay through circuit 1005 (VT/OG) when the ignition switch is in the START/RUN position. The
battery saver relay provides power to circuit 705 (LG/OG). Circuit 705 (LG/OG) provides power to each demand lamp switch which when activated
provides power to the selected demand lamp. The demand lamps are grounded through circuit 57 (BK). The battery saver deactivates the power circuit
when the instrument cluster releases the ground from the relay on circuit 1005 (VT/OG) after time-out.
