Radio won't work

[WJune]

Can't find this problem in search, so hope someone can help. My radio quit, no light even. Swapped in one from my other truck an still nothing. Fuse good, red wire to radio plug in at radio is live, radio is grounded. What am I missing. Don't have a schematic of wires to radio so can't bench test radio. Dought they both died though.

There are two hot wires needed to run the radio. One always hot for the memory, one key-on only hot to run the rest of the functions. My service manual is out in the shop, but if nobody can identify these wires by this afternoon or so, I will look it up for you.

Thanks, the red comes from fuse, so I need to know color and where the other live wire go's to.

On the grey connector (should be the same one you found the red hot wire), the pink wire is battery feed (always hot). The pink wire feeds through fuse #15, the red (actually red with white tracer) feeds through fuse #8. These are from a 1993 service manual, but all Chrysler radios from the mid 80's to late 90's are similar.

3 fuses power the radio as follows:

fuse # 8 10 amp red/white strip 20 gauge
fuse # 15 10 amp pink 20 gauge
fuse # 14 3 amp orange 20 gauge wire

On the radio the gray connector is for power & the black is for the speakers.

Fuse 14 is for the lghts and will only show hot when lights are turned on.

Yep, it also also runs through the dash-light dimmer, may have to turn it up.

Found my 90 Dodge owners manual which shows 3 wires for radio. #4 radio & clock is OK, #8 radio display intensity, out side lamps etc. was blown, replaced fuse which activated pink wire but still dead at radio connector. #11 radio & clock memory, interior lamps, is a pink wire that remains dead even though fuse is good. If I stick a nail at pink wire in back of fuse an jump hot to it, the radio comes on. For some reason that fuse is not getting juice? Simple solution is probably to cut pink wire at fuse and use a line fuse from a hot source. Don't want to replace whole fuse box.

If everything else (if anything) connected to this is OK, an inline fuse is a very workable solution.
