Circuit Operation
Radio Speaker Relay and Filter Choke Relay
CIRCUIT OPERATION
The radio speaker relay and filter choke supplies voltage to the amplifier circuits in the speakers. The radio supplies power to the coil side of the
relay on circuit X60. Circuit Z1 provides ground for the coil side of the relay
Circuit F31 from fuse 2 in the fuse block supplies power to the contact side of the relay. Circuit A3 from fuse 14 in the Power Distribution Center
(PDC) connects to the fuse block bus bar that feeds circuit F31 through fuse 2. Circuits A3 and F31 are HOT at all times.
When the radio supplies power for the coil side of the relay, the contacts close and connect circuits F31 and X13. Circuit X13 supplies voltage to
the amplifier circuits in the speakers. Circuit X15 provides ground for the amplifier circuit of the speakers.
