No power to radio need help

Alright so about a week ago my factory radio just shut off and never came back on. So thinking it was the radio burnt up I took the pioneer out of my truck that I knew for a fact worked in it and wired everything up, still not working so apparently no power. Checked the fuse and the fuse isn't burnt or nothing still looks good. Need some help as soon as possible don't know what it could be. This is in a 97 jeep wrangler TJ 2.5 4 cylinder automatic. Thanks in advance for any and all help!

Have you checked the fuse under the hood? I had that problem. And also there is a ground that goes onto the back of the stereo, I forgot to put that back on and it wouldn't turn on. Let me know if that works.

Use an electrical tester to check that there is power in the power source wire. Of course the ignition needs to be on. If you determine that you actually don't have power then, you can start diagnosing why by checking the fuses. Sometimes the fuses don't blow at the visible point. So, you might try changing them, instead of just looking at them. The fuse contacts could be dirty or rusted too.

I believe the radio fuse is behind the glove box. There is a connection panel like this one located near it behind the glove box. Here it is shown as fuse #14.

There is indeed a fuse for the radio behind the glove box, I have a fuse in the fuse box under the hood, I guess I'm just different lol, are you using a wrangler repair book for the diagram for the stereo?

This is supposedly from the 1997 Wrangler Owner's manual. Here it is fuse #15.

It was fuse 15 in mine behind the glovebox I took it out and looked at it the points were rusted but I took the fuse out of the door light because I knew it worked and still nothing. So should I try testing it or is there one under the hood or??

If you have one under the hood try it, if not, take the cigarette lighter and cut that, take your 12V constant and ground and connect it to that, it's like an alternate battery wire, that could be. I would agree with the other guy, check to see if you have power to the wire.

Are your turn signals and windshield wiper working? If not, it's your ignition switch.

Take the 12V positive wire, and your ground wire, that come out of the stereo, have them ready, take your (Cigarette lighter) and unplug it then cut it, about 4 to 6 inches from the plug itself, and them hook the 12V positive to the positive wire on the cigarette lighter, and hook your ground to the ground wire, see if it turns on

Wait I didn't realize you had power! My bad. One day I had the same problem, I took the ignition wire and the battery wire, the two coming from the stereo, and put them together, I know it sounds crazy, I took those two wires and put it on the battery wire, that makes it stay on all the time, if that works then you know it's the ignition

well after checking power checked my remote and had no power on it, didn't check the acc. one. but i hooked all positives together to power and took the ground loose and put it on a ground i knew was good. still nothing. i had to come in because right now it's got me so steamed i'm ready to rip it all apart. i don't see how nothing wants to work. then lucky me, in the middle of all this, my dome light bulb blew. then my phone went dead so i couldn't get on my app to get on here so plugged my car charger in, well what do you know the charger quit working too. today just aint my day it's been nothing but this one thing after another stuff for over a month.

Well all I can say is if you can't find the problem, it might be time to rewire. A buddy of mine had a problem similar and I just rewired it, one wire from the ignition, one from the battery, and new wiring to each speaker, fixed the problem.

i looked at everything i even tried the power and ground from the cigarette lighter. it won't do nothing. and i know it aint the cd player it worked fine in my truck so i just unhooked it and took it to the jeep and hooked it up and nothing. couldn't i leave the factory speaker wire and just cut it and hook into it? and even if i got the constant from the battery how in the world do i hook the remote and acc. into the ignition to work right? don't they hook up different?

Did you ever check your signals and your wipers?

I wouldn't have connected all the power wires together. That is probably what caused the malfunction that shorted out your lights and charger. I don't know why you just don't test the acc wire that you are plugging into your radio. It's quite simple and it will tell you if the circuit is bad or the radio is faulty. You can also check your ground wire with the same electrical tester. Just connect your acc to the clip and use the probe on the ground wire.

If the points are rusted then that could be the problem. But, I would check the acc wire first. It's like diagnosing a printer problem. In any diagnosis you check the obvious first. So, the first thing you do is to make sure it is on and getting power.

Confusing me now lol, if you can look in your wrangler book, look for the acc wire and see if there is power going to it when you turn the key, if not then you see your problem, also look on the back of the CD player, you could have shorted the fuse on the back of it, if it has one, that happened to me and it took forever to figure it out

my light blew before i hooked all positives together, my charger has been bad like that for a while, and how will the acc tell me if it's the circuit or the radio? i'll try more tomorrow it's pouring snow here and getting cold quick and now with nothing but a battery light it's hard to work in the dark. i rechecked fuse in fuse box, still good, checked one on back of cd player, good. it's dumbfounding me to death

If the acc isn't giving out power, then it's not going to turn on the stereo. Tomorrow do this


Radio
/ | \
/ | \
/ | \
Yellow. Red. Black
| / |

Red yellow Black

Car
Connect both red and yellow together, and connect them to the batter wire, I'm not sure if it's yellow or red, it won't harm the stereo, if it turns on then you will know it's the acc wire, and there is something wrong with the ignition

Exactly, you might get a spark or two, that's normal when doing this, you might pop a fuse, but it should power up, then you have to manually turn the stereo on and off, that is if you can't find the problem.

If you turn on the acc power and test the acc wire, going to the radio, and it lights, then you know the circuit is good, and the problem lies elsewhere. If it doesn't light, then you know there is a fault somewhere in the circuit. Then, you can try troubleshooting the circuit.

If you confirm that the acc circuit is good, and you test the ground wire, and it is good too, then you know the problem is the radio. I am of course assuming that the radio is connected properly.

yeah, well it should be good where it came out of my truck and worked fine but i'll check just to be sure it didn't die somewhere between the truck and jeep. give me a minute i might have a battery in the basement to test it on

Personally, I wouldn't do anything that causes sparks or blows fuses in my electrical system. Your air bag is in that circuit, if you mess it up you are going to be in big, big trouble.

When it comes to diagnostic testing, I don't ASS-U-ME anything. I check the obvious first. It may seem obvious that the ACC power going to your radio is a bad circuit. It seems obvious, but I would confirm it. If you confirm it, then you know for sure where the problem lies.

Then you can test the fuse panel. An electrical tester is only a few dollars. Everyone should have one if doing electrical work. I believe the problem is probably the rust in your fuse panel that you mentioned, but I would confirm it by testing the wire first and not assuming anything.
If you confirm it, then I would get some light sand paper, turn off the car, remove the radio fuse, and lightly sand the rust off of the fuse box connectors where the radio fuse goes. You can fold the sand paper to pencil size width and rub it between the connectors. Then, you can turn the car on and check that there is power on one side of the radio fuse holder where the radio fuse goes. That should fix it.

I wouldn't even test the radio outside of the Jeep. If it does spark, you could burn out your radio circuits, and completely ruin the radio.

But, you can do it your way. It's your radio and your Jeep. I think I'll just stay out of it at this point. Good Luck.
