Radio/Stereo: Description and Operation

INTRODUCTION
For operation of the factory installed standard and optional radios with cassette or compact disc player, refer to the Sound Systems Operating Instructions in the Owners Manual supplied with the vehicle.

The vehicles are shipped with fuse 13 removed from the junction block. The fuse replaces the ignition-off draw (IOD) connector. Fuse 13 is a ten amp fuse. When removed, it prevents the battery from discharging during storage.

SYSTEM OPERATION
Interference Elimination
Some components used on the vehicles are equipped with a capacitor to suppress radio frequency interference/static.

Capacitors are mounted in various locations internal to the generator, instrument cluster and windshield wiper motor.

Ground straps are mounted from the engine to each shock tower. The ground straps should be securely tightened to assure good metal to metal contact. Ground straps conduct very small high frequency electrical signals to ground and require clean large surface area contact. The radio grounds to the floor pan through a ground strap which bolts to the back of the radio from the instrument panel wire harness.
