Radio Choke
CIRCUIT OPERATION
The radio choke relay supplies voltage to the amplifier circuits in the speakers. The radio supplies power to the coil side of the relay on circuit
X60. Circuit Z2 provides ground for the coil side of the relay.
The radio energizes the radio choke relay by powering circuit X60. When the relay energizes, its contacts close and connect circuit M1 from the
Ignition-Off-Draw (IOD) fuse in cavity 17 of the fuse block to circuit X13. Circuit X13 supplies voltage to the amplifier circuits in the speakers.
