i hooked up my new stereo a little while ago, only to find that it wouldn't even turn on...well after a little trial and error i discovered that there is no current in the yellow wire that connects to the stereo....
if i connect the yellow wire directly to the battery the stereo works fine,
so my guess is the fuse somewhere for that wire is shorted, but where is the fuse...
or what else can be wrong?
thanks

 

Hmmm... Are you turning the key to "ON"? The yellow wire is for Memory, only has 12v when the key is in the "ON" or "ACC" positions. The fuse will be in the fuse panel, under the dash. If you snapped this fuse then your windows would not work (if power), dummy lights, etc... I dont know what else to say.

What kind of car is this, radio? Need more info.

 

regular ol aiwa cd deck...

 

Did you try swapping the red and yellow wires? I mean yellow from the stereo to red of the car, and red from the stereo to yellow of the car?

I'm having some serious brain farts right now.

What car?

 

Well your yellow wire is supposed to be a constant 12v. So there are a couple of ways to fix your problem. The easiest would be to splice into your cig. lighter ONLY IF your lighter works with the car off and key off. If your lighter wont work just find the red wire in your ignition harness and splice into that...

The wire colors on your aiwa deck WILL NOT exactly match those of the vehicle. A wire harness is always the preferred method. The constant 12v wire in the OEM harness is orange.

 

i am using a harness... the yellow wire on the harness wa the constant 12v, it used to work i hooked up my last stereo and it worked fine... but now there is no voltage going to that wire...
i think i may have shorted it out, but how do i get it back?
