I have a 1994 Ford Escort wagon. The radio isn't working. It lights up when the headlights are on, but no digital readout or sound. It looks like there are 4 power wires coming into the radio. Two have power, I belive one is for the memory & one is for the illumination. The other two have no power. I checked the fuses by the driver's side door and they're all good. I traced the wires on the harness back as far as I could see and they all look good. Any ideas? I only have so many songs I can sing to myself!
Check for fuses under the hood? and I think that the wires are memory illumination power and acc./ ant. probably a momentary hot controlled by the radio itself. used for factory amplifiers and electric antenna. so you should have...
the constant hot (memory)
only hot when lights are on (ill.)
only hot when radio is turned on (amp / ant)
and switched.
thats why I think there must be a fuse under the hood
I'll look for a diagram and post back. what I find
Thick Brown - Earth/0V
/ ground
Red - 12V Battery Constant
/ memory
Thick Yellow - 12V Ignition
/ switched power
Grey/Yellow - Illumination/Dashboard Lighting
Blue _ Power Antenna
thats on the 5 wire connector in the back of the radio
check the yellow wire for power with the ignition on, if none is found the check for power at the radio fuse in the fusebox. if you have power on the fuse but not on the yellow wire you might try running a jumper from the fuse to the yellow wire, if this causes the radio to function then you have a bad connection somewhere in the dash.

Ignition on and backup power must be present in order for the radio to turn on.The backlighting is another circuit.access the connector at the back of the radio check power supply if both are present

I checked for fuses under the hood and found one panel with about 6 large fuses. None seemed to pertain to my radio problem. The main 100A fuse was still good, and the others were for the cooling fan, air bag, and some other large items. Any other ideas?
