Fuse/Radio problems

My radio doesn't work after my battery cables came loose from the battery on a road trip. The radio worked while i was driving but once i fixed the cables thee radio wont work. I don't know if its a blown fuse or what, but the fuse under my dash for the radio is gone after a shop looked at it and i don't know what to replace it with. it doesnt look like a normal 2 blade fuse, but something with one blade and the body of the fuse in the shape of a staircase.

Also the missing fuse is on the bottom left of the under dash fuse panel, with radio written below it. If somebody could look at theirs and help me out i would greatly appreciate it. Mine is a 92 by the way

Well mine did that ... for some reason no fuse goes in the radio slot ... it should be the ACC fuse nearest to the radio slot ... check that fuse, it controls the radio and 12v outlet.

I replaced the one above the radio fuse which said ACC, replaced it with a 30 amp fuse, and the one to the right of the RADIO fuse said ACC LMPS, replaced it with a 5 amp fuse and got nothing. Maybe its the fuse on the head unit? I am so lost....

Yea some head units have as I recall 10 or 5 amp mini blade fuses on the back ... maybe thats where your problem lies, as for the ACC I dont know either just confuses people took me forever to figure it out why even have the radio slot?

Did you get around this issue? Im having the same exact issue. My radio wont work, however my cigarette lighter works. I just pulled out my aftermarket headunit, theres a red 10 amp fuse behind it and it still looks good. However, Im still trying to figure out the whole deal with the radio fuse underneath the dashboard, and the other two slots ACC & ACC Lamp. Any help would be greatly aprecitated. Also, my overhead lamp does not work. im lostt.... help.

Most after market radios have an in line fuse in the main power + wire somewhere. The radio slot on the fuse box is a connection for a cb radio.

Thanks, my radio does have a fuse, the power just isn't enough to power the radio. The secondary power wire will get a little power for just a second then nothing. Anyone have any luck with after market install without re-wiring? could ther be a reason I'm not getting enough power?

The power is a constant. A radio can run run even if the battery is almost dead. If the radio is good for sure then it has to be in wiring. Either the power wire has a bad connection or your ground is bad. There is a lot of vibration in jeeps and things do shake loose alot.

My 1991 radio won't work

The radio is 12 volt but the battery puts out 24 volts. Does anyone know what I can do to get this radio working?

Thanks

I have replaced all of my stock stereo wiring. I have a alpine deck , two tens , 6 6x9s and two amps. Your wires are the most plausible. My stereo sounded horrible. I redid everything and it's sounding amazing! It was really cheap too.

That's a new one for me!! Have never seen a 24v battery in any automotive application. The only thing I've seen even on big trucks and construction equipment is 12v batteries.. The old jeeps used 2, 6v batteries in series to get 12v, some of the old military jeeps had 24v systems but then we all know the government is screwed up!! Have never seen any newer jeeps with a 24 v system.

Your battery putting out 24 volts doesn't seem right. The vehicle runs on a 12V system, and unless you have two batteries wired in series, and you shouldn't, you should not be seeing 24v on any of your wires.

I am actually curious if I am having the same problem as other folks in this thread. The previous owner ran a seperate wire off the fuse box and tee'd it into the radio harness. I did a little bit of looking around when I installed my new HU but couldn't find any problems. All fuses were so I figured there was a broken wire somewhere behind the dash and it just went on my rewiring to-do list.

make sure there wasn't a small wire w/washer style hook up on one of the battery terminal bolts. Sometimes its an extra wire there. Also look around all over under the hood for a wire being added with an inline fuse somewhere.

I had this same problem..Fuses all check out and i get power to the ignition wire but the constant wouldnt work. I ended up just running a wire to an empty constant slot on the fuse box with an inline fuse. Possibly clock slot but i dont remember. I would like to know what went wrong though since my cig lighter still dont work.

I have all the same symptoms 88, except when I pull the radio wire out of the clock fuse spot, I still have power to the cig lighter. Initially it blew my mind since the manual showed both pieces getting power from the same fuse slot.

These things are relatively easy to work on but sometimes I wonder if the sub contracted the electrical work "somewhere else".

You can find 24 to 12 volt converters on Ebay.

I'm assuming that it is a diesel conversion 24 volt system. Most that I have seen use 2 12 volt batteries in series so 12 volts is still available for the radio and other accessories.

Need more information to help further.
