Radio Operation

CIRCUIT OPERATION
There are two audio systems offered on this vehicle. The base system uses six speakers and a standard antenna. The optional system has six speakers, power Amplifier, and a power antenna.

Both systems are powered by a 10 Amp fuse located in cavity 14 of the junction block on circuit X12. This fuse is HOT when the ignition switch is in the ACCESSORY or RUN position.

The A31 circuit which receives it's power from the ignition switch, on circuit A1, is protected by a 20 Amp fuse located in cavity 8 of the Power Distribution Center (PDC).

Both the standard and optional radios use an external case ground. This case ground attaches to the rear of the radio and the instrument panel. There is also a ground for the radio provided on circuit Z1. This circuit attaches to the rear of the radio and terminates at the instrument panel ground.
