INSTALLATION
The drawing below shows the correct mounting method for all “B” body dashes. Even though the radio is much smaller and lighter
than the original, It will go into the dash the same way that the old one came out. After removing the original radio, remove the
original mounting bracket and replace it with the one provided with your new radio. Put the slotted end on the gusset stud to allow for
adjustment. Remove the control knobs and backrings by pulling straight off. Remove the outer hex nuts from the control shafts.
Do
Not
remove or loosen the inner hex nuts that hold the control shafts and spacers in place. Remove the mounting screw from the lower
right side of the black dial housing. Set the radio into the dash and hold it in place with the two hex nuts. Put the mounting screw
through the cluster mtg. and screw into the dial housing as shown below. Do not over-tighten the hex nuts or mounting screw. Slide
the free hanging end of the radio mounting bracket over the stud on the passenger side of the radio housing and secure with the 7/16”
mounting nut provided. Plug the antenna into the jack on the lower rear of the radio near the mounting stud.
DIAGNOSTICS
No Sound:
Check for a good fuse with proper rating. When the radio is turned on, the orange wire should have 12 volts present. Every
speaker lead should measure about 6 volts to ground with the radio on and volume low. During start up diagnostics if the radio detects
a shorted speaker wire the radio will shut off that speaker lead until the issue is resolved. The Radio will mute when no station is
received. Make sure the antenna is plugged into the proper jack. If an accessory is not connected there will be no audio in auxillary
mode.
Weak or No Reception:
Check continuity between the center pin of the antenna plug and the antenna mast. It should read 0 ohms
(like a short) Next, check continuity between the center pin of the antenna plug and the car body. It should not read (like an open
circuit). If you’re in a metal building, reception may be limited. Try it outside
. Connect an accessory in auxillary mode to make sure
sound is present.
Ignition Noise:
Usually caused by an ungrounded antenna shield. The base of the antenna must make good contact with the car body.
This problem often shows up after a good paint job! Make sure the engine grounding straps are in place, clean and tightly bonded to
the frame.
Distortion:
Check to see if your speakers can handle at least 45 watts RMS. Small speakers that can only reproduce high frequency
will distort on bass notes. Make sure speakers are properly installed. Make sure that no speaker is grounded. Every speaker lead
should measure about 6 volts to ground with the radio on and volume low. Resistance in the DC power input wiring can cause the
amplifiers to “starve”. If distortion seems to increase with volume, measure the voltage on the orange wire. If the voltage drops when
the volume is raised, it is an indication of resistance between the battery and the radio – usually at the fuse block, but sometimes in the
ignition switch. If the backstrap is not bolted to a clean metal ground, try running a heavy ground wire from the ground lug on the
radio directly to the firewall.
Radio shuts off after a few minutes:
The radio has thermal protection built in to prevent damage from excessive heat. Possible
causes are shorted or grounded speaker wires. See if any unused wires can touch anything. Make sure the heater or defroster duct isn’t
blowing directly on the radio.
Dial pointer issues:
If the dial pointer gets stuck at one end or if it is misaligned, hold down one of the 5 preset buttons for 5-10
seconds to realign or free dial pointer. If the dial pointer is stuck at one end of the dial, turn the tuning knob. The dial pointer should
try to move while you're turning the knob. Continue to turn the tuning knob until the pointer resets itself.
BE SAFE:
Make sure you are familiar with the way this radio works before you go out on the road. Driving demands your full
attention. Texting while driving is dangerous and it is illegal in many states. Remember: not all drivers have hands free phones, so the
guy next to you may be driving while distracted.
