Radio

Hello on my 1975 ford f250 my radio when I purchased it does not work it only has 37,000 original miles so I highly dought the radio is bad but my question is is there possibly a fue I can check for the radio and is it a AM or AM FM radio I think it is AM because there is no FM bottom here is a picture of it.

Radios going bad is typical. I have half a dozen original ones and none of them work.

Have a
. This is probably the block you have. The vehicle in that thread had a radio with no radio circuit in the fuse block too.

Well I know that older (73-75/76?) trucks have a smaller fuze block, unless I am going crazy.

redroad the web is being cranky today, so just me.

Bobby yes ck all five and see if you have an inline fuse in the radio wiring.

Yes thanks will fist bump you for the help I did check the inline fuse for the radio that's okay but that wire was cut off so I wire nutted it and it still won't work so if I cant get it going I think I will take it to a radio shop and they might be able to fix it.

Maybe a local radio shop can help, but it not."The OEM radio was powered by a GREEN 2-terminal pigtail. YELLOW with a BLACK stripe is switched power, BLUE with RED stripe is dash illumination. Do not mistake the BLUE with RED stripe wire for ground. The OEM radio grounded through its mounting chassis. The speakers were connected over a separate pigtail.

Looked behind the glove box and find a connection the goes off the green and yellow. GREEN with YELLOW stripe wiring is hot-at-all-times power for the courtesy lamp circuit. Use that. There is a black 3-connector pigtail behind the glove box (which also goes on to power the cigarette lighter).

It's not the stock radio wire because the stock radio didn't need hot-at-all-times power (EXCEPT the factory digital AM radio for clock memory).

solid black—power
blue with red stripe--dial light
black with gray dashes—ground
orange with green dashes--right speaker
white with green dashes--left speaker


Assuming an AM/FM stereo and stock wiring harness'. Purple is ground, right speaker is white and left speaker is orange.

A blast from the past, "For OEM radio help, the guy to use is in Scottsbluff Nebraska. His name is Gene Cochran, and he works out of his house. He's a crusty old codger, but does some tremendous work. While he had the radio apart, he updated some of the internals and cleaned the heck out of everything. My total bill was $25! His number is 308 632-2520 (I checked with him at the time I collected my stereo, and he was OK with giving his number out) He also lined me out on the manner in which the old radios were wired (mine at least). The speakers are in series meaning positive from radio to positive on speaker #1, negative from that speaker goes to positive on speaker #2. Negative from Speaker #2 goes to Negative on stereo. Now the stock stereo rocks as loud as the little 5 1/2 speakers can handle!!!

While it's there you might see if he'll wire in an aux input jack. I had it done with mine, and it allows me to run my I-pod through it. Basically, when the I-pod is connected it becomes the antenna source. Cost in parts was under $5. I set mine on a 12" extension so I could just drill a small hole in the dash by the ashtray, which I'm turning into a covert charging / storage station for my phone and I-pod. won't cost much more."

#1 problem of these radios is simply not getting power, blown fuse or no connection

And also speaker or antenna disconnected…

#2 is the brittle paper speaker cone disintegrating.

#3 dirty volume pot/tuner-squirt some plastic safe electric contact cleaner in the switches and controls and work them back and forth.

#4 is electrolytic capacitors-they have a shelf life of 20 yrs much less in a hot and vibrating environment.

first things first, make sure it is getting 12 VDC and its all hooked up properly and that your speaker isn’t gone.

Okay do you know how to check to see if the radio is getting power which wire it will be?

Yes the radio may not be getting any power at all which wire do I check to see if I have power to it, also does this guy in Nebraska ship radio and would he have any ones on hand to sell I like the am radio if it will work but I would like to get a original 73 to 77 ford truck radio but with FM too because I have other stations I like but don't want to put a digital one in Thanks for the help.
