Car radio don't work but it does have power

So the radio (maxtek 55401) works fine when first connected, so in it goes. A quick test of ignition off and on again and it still works. However if the car is left off for any length of time, the radio doesn't come back on. When I start the car, the backlight comes on, but it won't actually turn on. Then when I turn the car off, it beeps for 5 seconds and then fades for 2 seconds then is cut off. I assumed it was the ground connector(black&yellow AND black&green), for which the radio instructions and other the internet sources seemed to disagree, but i've tried it both ways and it gives the same result. could it be a security feature? or could it be something to do with the power antenna lead (unused) all help MUCH appreciated thanks mike

red = 12 volts switched (ignition)
yellow = 12 volts constant
black = ground
blue = power antenna
blue/ white = amp turn on

purples = right rear
grays = right front
greens = left rear
whites = right front

black striped speaker wires are negative side

SOURCE: Car just stopped running. Lost power suddenly.

Find an inductive pickup indicator for spark. Place on distributor cap to see if spark is at coil internal tower. If no spark at internal tower, look at ignition module or pickup coil. Ignition modules are prone to failure on 626's. But if you have spark at tower but not at the wire end, then your rotor is gone.

Check the power supply. Take out the whole supply unit and try it also on another machine.
May need replacement.

All you can do is trace the wiring back from the radio to the speakers, there is no quick fix here. To test the speakers touch a battery to the two contacts, the speaker will pop if it is any good.

When i start my ford escape the radio goes on for about 2 minutes and then shuts off. Then it doesnt work until i shut the car off and leave the key in the ignition. cant figure out what is wrong with it

Check your radio relay. If it has bad contacts, it will cause the radio to shut down; when you turn the key off, it recycles the relay. Your relay may need to be replaced. You could try swapping it out with another relay from the box to give it a quick test. Just make sure you don't disable anything that wouls make your vehicle unsafe.

I have a 2009 pontiac vibe with a radio that seems to ONLY work when the key is in the ACC mdoe. When I start the car, the radio and display goes off completely. When I press the Clock button the times...

Incorrectly wired, the supply going to the main power goes to the ACC only and not the main power or the ignition switch is faulty if nothing else works like blower etc.

Van dormant for three years. installed new battery,started and ran good for two hours, died, fuel guage malfunctioned(still),radio stopped working(still),i.e.,no 12 volts to orange wire. installed new...

The fuel gauge is probably fine, its the sending unit that is probably bad. As far as the radio I would run another power wire from 1 of the accessory ports on the fuse box. Just make sure you test the port so it goes on and off with your ignition. Just test the port with a light tester. Please rate answer!! Thank you

The radio dosent work i replaced it and it still dosent work. I also replaced the processor and still nothing. I checked the power to the radio and its fine. Im stumped.

That is odd... you say you replaced the stereo? Is it the original (OEM) stereo? If it isn't, the way to easily test the stereo's ability to power up or not, is to connect the red and yellow leads to the positive post of your car battery, and the black lead to the negative post. If the stereo is good, it should power up no problem. If it is the OEM, and you're just replacing the stock stereo, it could be a dead short (wire grounding out). The way to test that is to buy a test light (most any parts store carries them), turn the ignition switch to on, and check the wiring harness for the back of the stereo. You would attach the clamp to any unpainted metal surface in your car that is connected to the chassis, and put the test lead in each receptacle in the harness. At least 2 connections should light the test bulb up with the ignition in the on position. I don't know the schematics for it offhand, so I couldn't tell you which color wires should be lit ><. Hope this helps!

How do you install a jvc cd player in a 95 carolla is the colors the same

Most new radios have a diagram or wiring scheme that tells you which wire goes where. Usually there are 2 power wires(one goes to ignition wire and the other to the battery B+ wire). Then there are the Power antenna and Ground wires. Once you have these in place you can figure out the speaker wires. #1 You need a DMM (Digital Multimeter), wirecutters, wirenuts, lineman pliers and electric tape. #2 There are only 2 wires that should put out a voltage. So set your DMM to DC voltage at 20 voltage range. (If your battery is 24V set your DMM to next highest range.) Connect the black test lead of your DMM to ground(usually a black wire). Connect your red test lead of your DMM to all of the dash wires ONE AT A TIME until you find ONE that puts out a voltage of approx. 12 V. That is your Battery B+ wire. Mark it and set it aside. Now to find the ignition wire. Note that your ignition wire will not put out a voltage until you turn the ignition ON. So turn ignition ON and find it by connecting blacl test lead of DMM to ground wire and the red test lead of DMM to each of the remaining wires until you read 12 V. Be sure to double check by reading both wires while ignition ON and OFF. Mark the Ignition wire and set aside. #3 Now that the wires that put out a voltage are out of the way, set your DMM to Continuity Tester. This test is done with power off(no more power emitting wires anymore remember). This test checks for continuity or a path which current can flow through. It does so by 'BEEPING' when the leads are connected to both ends of a connecting wire. So start checking the wires by connecting black lead to one wire and red to another wire. Mismatch until you find two that will make a beep. That pair of wires connect to a speaker. Band the pair together and find 3 more pairs. Those four pairs are the wires to the four speakers in your car. #4 You can now make the proper connections using the wiring scheme on the radio. So far you can connect the ignition wire and the battery wire. Theoretically if you were to turn on the ignition power is going into the radio but the negative/ground needs to be connected for the power to flow. Other than the other 8 speakers wires there should only be 2 wires remaining coming out of the dash. One would be the ground and the other the power antenna. With the ignition on and the radio turned on tap the power antenna wire from the radio to one of the 2 remaining wires. Taping the ground would not power the antenna but taping the power antenna wire will. So find out which is the power antenna by quickly tapping it. Most ppl would not recommend this type of testing. Make proper connections once finding which is which. #5 At this point the wiring scheme on the radio tells which pair of speaker wires is for which of the four speakers in the car. 1) rear right; 2) rear left; 3) front right; and 4) front left. With the ignition on and the car radio on take any pair from the radio and soft connect to a pair on the car. One of the speakers will play. Note which one and find its coresponding connection on the wiring scheme. Do two more in the same manner which would only left one on the car and one pair on the radio. #6 Remember to make good connections using the linemans pliers to twist the wires tightly together. Plus secure all connections with wire nuts and to be safe also secure with the electric tape. Try to keep wires neat and secure. I hope this helps. =)

Radio turns off in starting position

this look like a low battery and every time you try to crank your car it takes more power and kill the main power to the radio
solution # 2 the radio as 2 power wires one is always hot ( with current) and the other is connected to the ignition switch if you have replaced the radio those 2 wires maybe are connected backwards the one that goes to the switch is probably connected directly to the battery and the one is suppose to be always hot is probably connected to the switch if you have the original radio have your battery tested and if is ok then try get a haynes book at any auto parts for you car and try to follow the wire that is always hot normally is a yellow or orange wire
solution #3 this apply only if you car still have the original radio
turn your ignition switch to the on position but don't crank your car and turn your radio on select a radio station then turn your ignition key off and wait 3 minutes then turn your ignition switch on again with out cranking your car and the radio should be in the same radio station you select if this test pass then chances are is your battery getting low and if this test fail then the hot wire has a blow fuse look for the fuse inside the hook let me know what happend and good luck
