Radio

The radio receives battery voltage at all times on circuit 640 through the RADIO BATT fuse in order to keep the clock and preset memory alive when the ignition is in the OFF position. The radio is grounded through circuit 351. When the ignition is in the ACCY or RUN position:
^ Voltage is applied to circuit 43 through the RADIO fuse to enable the radio operation
^ The Vacuum Florescent (VF) display illuminates to display the time or radio frequency setting with the ignition switch.
