Radio won't turn on

I've been getting help from 81 Explorer on alot of this,but I think posting here might help get me an answer from someone who might have been through this before.I recently swapped in an 85 Electronic Radio to my 1980 F100.Well,everything is plugged in,but the Radio will not come on.It has power at the connector,even on the radio side.I took the radio apart to test the wires at each connection on the circuit board.The yellow/black hash wire connected to the circuit board,and then came out as a green wire that ran to the power switch on the front of the radio.Then,another green wire came off a second terminal on the switch and ran to another part of the circuit board.When I click the power button,the green wire that comes from yellow/black has power.When I press the switch again,both green wires have power,which I guess means the radio is on.So it looks like the switch is working.Does anybody else know what might be wrong?It seems to be getting power at every connection.

Check to make sure you have a good ground connection. You can use a "temporary jumper" wire and ground to the radio chassis to check. Sometimes you wont get output if the antenna plug is defective. Some radios wont have output if the constant 12V wire for memory presets, clock doesn't have a good source.

Well,the springy metal thing on the radio is clean,and the part is slides onto on the dash support is clean and bare metal,so I wouldn't imagine it's a ground problem.I might still try the jumper wire though to be sure.Antenna plug seems to be okay.I have a spare that if all else fails,i'll try.The memory wire comes out of the clock circuit,and has power all the way to the connector also,so it shouldn't be that.

I'll try the jumper wire and see what that does.

*EDIT:Well,the jumper wire didn't make any difference.

Are you not getting the face to light up when you turn the radio on?

The words light up,but the station number face does not light up.

I tried the jumper wire,but it didn't make any difference.

Well it sounds as though you have covered all the bases. You need a good ground, a good 12V switched power source and a good 12V constant power supply to make it work. Sounds like it could be the radio?

That's what I think to, the radio sounds like it is DOA.

Didn't intend to have you chasing shadows, I know you know what you're doing but it's always a good idea I think to double check power and ground before making a determination on the electrical equipment itself. That's what I do anyhow. Good luck with it.

I've checked the power sources so many times it's not even funny.I've even tried contact cleaner just to be sure there wasn't dirt buildup.I'm beginning to also think the Radio is DOA.Is there anyway to fix a radio,or is it a lost cause?I heard it's expensive.

Yeah you can have it fixed. Even if it's a super simple fix you'll probably pay a shop minimum which will most likely be more than replacing the one you have at your local pick and pull.

I got a killer Alpine head unit with a passive EQ at my local JY for 13 bucks. I already had amps and nice Kenwood CD/DVD player I took out of my '06 before I traded it. I want to eventually put the player in my '09. I put the alpine head, eq, 3 amps and 11 speakers in the '83. Think I'm gonna go as stock as I can in my '09 other than a couple of pairs of speakers and the new head unit

Depends on what's wrong with it. I've fixed several myself but it's not for the novice.

You need the testing equipment, and a place to get parts from etc... Potentiomiters, Diodes, resistors, tubes, transistors, etc... You also need the knowledge of how to solder, and how to follow circuts in a circut board. Then there are parts not avaliable anywhere else than with another broken radio, exactly like yours to get parts from. And hopefully it's not broke in the same way etc...

First thing I'd check is to look inside for any dry or cracked solder joints, especially where the radio ground wire attaches to the radio chassis on the inside. If it all looks good you can clean the inside of the radio with electronic cleaner if it's really dusty and dirty inside.

Other than that, not much help for it.

Unlike most of my friends,I have the confidence and enough knowledge to probably do it,but like you said,it's a matter of finding the parts.I'll probably take it apart tomorrow and look for dry solder joints and see where that leads me.If I don't find anything,then i'll just pronounce it dead and start looking for another one.Thanks for the help y'all.

I killed at least one of these radios resulting in the exact same scenario by
erroneously applying power to the orange wire.

That I know for sure I did not do.I checked and double checked my wire colors and location in the connectors before I even plugged them in.
