You need to plug this back in to activate the player and remove the cd's or disassemble the unit to pull them out.There is too much to happen to just power up one circuit. Good Luck.

SOURCE: 12v constant for 93 buick lesabre

It is usually a yellow wire. You may also use the wire from the cigarette lighter or any wire that is a constant 12 volts.

SOURCE: 12v power port (not cigarette

it sucks power through anything it's plugged into, like a power outlet on a wall, even something turned off takes a tiny amount from it. you have to unplug it every time you cut the car off. or did you want someone to tell you a way to rig it! that's why you have a freaking radar detector, you're a speeder, you should just get rid of the damn thing honestly, they can ticket a parked car with one of those.

SOURCE: what is the wirer color diagram 1999 toyota avalon car stereo radio wiring diagram radioconstant12v+wire??

Hi Slick, From my experience working on Toyota motor vehicles, they don't use colour coding. You'll need to identify the cables with a voltmeter and an used AA or AAA battery (like those from the TV remote). First find the constant power (which keeps the memory function of the set powered. Then by a process of elimination turn on the ignition and check each of the other cables until you find the ignition switched power. Check to make sure it' switched by turning the ignition on and off. To identify the speaker cables there should be a number of white cables with black tracer lines. Take any pair (removing a little insulation from the end to leave the metal cable open) and hold one cable onto the negative end of the battery and swipe the other cable end over the positive. As you do that the cable speaker will make a popping sound, where by you can identify which speaker is attached to what set of cables. Regards John

SOURCE: Hi,I have a becker radio model 744 with 4 pins to connect for power can't seem to figure out how to wire on my honda 2nd generation all wires still original on car and radio.

Use a VOM meter to check when the power is active on each of the four lines. My suspicion is that one is for power, one is for lights bright on the radio one is for lights low on the radio and one is probably the anti theft connection.

Is the car radio accessory switched 12v + wire the wire I connect my steering wheel controls wire from my knew radio to?


Depends on the set up. It will supply 12v power to any accessory connected to it when the radio is turned on. By accessory, I mean : powered amplifiers with relays, motorized antennas, additional audio components. Most likely it is to power an external amplifier or sub woofer.

Left speaker in lancer not working


test the speaker.
connect a 1.5vdc battery to it, (yes, unplugged)
does click? then its good enough to make noise.
use a test speaker at the connector, that works.?
if not the radio is bad or the wire are cut.
to prove that, connect a speaker directly to the radio left pin.
works , good radio.
i cut the line at the radio as soon as the speaker tests good
because grounded out (shorted) lines blow radio amps to smithereens.
can pull the radio first. then bench test it.
its super easy with one test speaker . and a 12v power source.
but be careful many radios brick (shows, enter code) if you pull it.

get your radio code first and this solves this issue.
many radios kill audio only bricked, left and right channels.
but tunes ok .

96 toyota camery, radio has no memory, have to find the channel each time i start the car


The radio has two pins for power connection. The one is active only when the carkey has been turned, the other is always live with 12V to keep the radio settings. It sounds like it is only powered by the key dependant power, and not the "always-on" for the radio memory.

The radio in my toyota echo locks and requires the security code every time the engine is started. Does anyone know the cause of this fault?


Is this the factory radio? It seems it is loosing power when the car is shut off. A car radio usually has two wires for power.... one that retains memory (usually yellow) and one that is tied into the cars ignition switch (normally red). You would need to track down the fuse or connection for the constant 12v power that the memory wire is connected to.

I was having this problem with the Honda radio and I have since replaced it with an after market one. I still have the problem with needing to disconnect the battery for the radio to work for a little...


a new radio?, or used, make and model # , must i guess?
all modes on the radio dead, AM/FM,CD/USB/IPOD jack
ALL, that be the first tests and if all bad that means you lost power.
does the radio scan? show signs its trying? when asked, LCD live? or dead. all i know is the word PROBLEM (vast possible)
did you ask the maker of said radio.
did you follow the new radio's instructions sheet.?

disconnecting the battery, wow !

the radios can have 3 or 4 power pins.
1: Radio power (head end power)
2: dial light (goes to car park dimmer)
3: some have a memory wire, if not connected all programming will be lost. this must go to HOT ALL TIMES line.
4: electric antenna, (it's an output but is power)]

and at least 1 good speaker connected.
and for AM/FM any test antenna or just a wire 12ft long works.
the radio can be bench tests.
1 battery 12v
1 radio
1 speak or 2.
1 antenna. now can test for days like this..... anyone.

I have an 89 camaro rs, I am getting power to the red power wire on my radio, but when I turn on the car I get no response and cd radio will not work. Any ideas?


there are two power wires to most radios. usually red and yellow. the red wire provides 12v when the key is turned on and yellow provides a constant 12v. both must have power to turn the radio on. there will be two fuses for the radio also so make sure both fuses are good. the only other thing that will keep the radio from coming on is the ground wire "usually black" that has to be connected to the ground in the factory harness or you can just connect it to any bare metal behind the dash

My radio is loosing preset after turning off ignition. 2002 tundra


If you just installed the radio its possible the power wire for the radio memory and clock is not hooked up to a constant hot 12v source. Also if all wiring is correct its possible there a bad connection or contact check connecters.
I had the first problem with a JVC radio I installed once it did not have clear instructions on the always 12v hot wires.

My dash lights and my radio stop workin when i was installing a new radio, how can i fix this?


sounds like you have a problem with the power supply. Check the fuse. if ok, remove the new radio and check the power connection to the radio. if you cut into a wire harnis to find a hot 12v connection, you may have severed the dash 12v supply or knocked it loose . Take it slow and retrace your steps, but first check the fuse panel. You may have shorted out a wire without knowing it when attempting the install. lift the pos. lead on you battery the next time you play with 12v.
