Fuse for 12v constant wire to radio?

I'm trying to install a new headunit in my 2004 Honda Civic. Is there a fuse for the 12v constant wire? If so, which one is it? I either shorted it or blew the fuse and would like to know if I can just replace a fuse before scrapping it and running a wire directly to the battery.

Thanks. This is my first time installing a radio on my own.

If you run a wire from the battery make sure you use a inline fuse.

It sounds like you have a constant 12V power supply wired to the radio instead of a switched 12V. If you've recently installed a new radio, check your wires again. There should be a 12V constant and a 12V switched. The switched 12V will turn the radio off, while the constant 12V is for keeping the clock and radio memory working.

2004 honda civic driver side headlight won't work even with new

Assuming you've already ruled out that the bulb is fine, get a test light and verify there is power (make sure headlights on when doing this). If there's no power check headlight fuses with test light. If fuses check out okay, there may be a break in the wire between the fusebox and headlamp, follow the wire and check it for damages...

When I don't have access to a test light, i use any 12v car light and hook it up, but if you have to do this make sure the makeshift test light is fused or you could destroy it. Yes power should be 12 Volts DC.

No key on radio power

There are 3 wires that deal with power on a aftermarket radio (Red is the wire that makes the stereo turn on with the key) (Yellow is constant power it is to keep your clock set and your presets of your radio stations ) and the black is the ground.

I have a 2001 kia sephia and i am installing a new radio. i had to cut the wires and put a new harness. i cannot find the wire coming from the car that is the constant 12V wire that is always live, so that...

Ok theirs two easy ways you could fix this problem one way just in case you haven't done it yet is buying a car light tester and check every wire you cut and when you find a wire that has power make sure it keeps having power with the car on and off. Ok and the second way is if you couldn't do it the first way then you got to just make a constant 12V wire and that could be done many ways you could run a wire directly from the battery or find a fuse that has constant 12V and run a wire strait from there you could find a constant 12V fuse whit the light tester and if you do it this way just make sure you put a fuse holder on the wire your running well I hop this will help you.

No constant Bat. for the radio. for a 1995 Honda civic.

Hi and welcome to FixYa,

Offhand on most car radio, the yellow wire should be connected to an always on B+12 source (such as the one connected to the + terminal of the battery); the red would be connected to an ACC B+12 such as the a wire from the IGN switch and of course the black to the GND. A fuse would be inline on either or both the yellow and red. The fuse holder would look like a tubular lump along the wiring sometimes black or translucent. In some instances, there would be a fuse holder below the connector at the rear of the radio. To determine always on 12 and ACC 12, a voltmeter would come in handy.

Good luck and Thank you for using FixYa.

I need radio wiring diagram for 2004 honda civic sedan and instructions on how to remove the radio

I just installed a radio and speakers in my 1992 Civic LX (132323 miles). Most radios are removed by disassembling some of the dashboard components. On mine I had to remove the lower center console (where the ashtray/lighter is located) to access the rear of my old radio. There is a metal support strap back there which stabilizes the radio and provides equipment grounding. This has to be removed from the radio before you can un-install the radio. Also there may be a metal mounting sleeve around the radio, if so you must use (2) thin metal strips (or thin screwdrivers)to disengage the (2) side clips from the sleeve. You should then be able to remove your old radio.
As for wiring , I had to discard the wire harness the came from the old stereo and hard wire the new unit. I used a 12v circuit tester to find my (+) positive (typically red) and (-) negative (typically black) leads. Speaker wires are in pairs. (example: blue/white white/blue or white/white-black)
