There may be more than one problem. The fact that the radio AND the amp are seeing a voltage of 7v indicates that the battery is weak or there is a bad connection somewhere in the power line.

It's also possible that the amp is defective (shorted output transistors?) and when it turns on, it's drawing excessive current. That would cause the voltage to drop more than normal. If the amp is drawing excessive current AND there is a bad connection in the power line, the amp may begin to blow fuses (depending on the reaction time of the protection circuit) when you repair the power line problem.

Got given a CB radio.. from a trucker... im in the [UK] wanting to put it in my car.. accept the voltage difference... a truck's voltage is about 24-volt's.. compared to a car.. only being 12...


I don't think there is a in accessories. The 24 volt truck systems are Cranking and Lighting. Either way you have no risk at trying the lower 12 volt car electrical. The problem is when you reverse polarity.

Keep blowing fuse for radio what is colr of constant wire


The constant 12 volt wire is yellow. The accessory ( switched 12 volt wire) is red. The blue (power antenna) and blue/white (remote amp turn on) are also switched 12 volt wires. Make sure that they are not being grounded.

Wont turn on. everything should be connected properly, got new fuses to make sure. It worked fine until i dismounted and disconnected it from the battery. When i reconnected it, no luck it is a Autotek...


Make sure this high powered amp is not mounted directly to the chassis of the car. Mount it to a wooden board and you can screw board into the car. Because some very high powered amps can arc and damage itself.

Next make sure the tubular fuse in the hood is not bad it may look good but internally it got real hot and caused a bad solder connect in the fuse. You can test it with a meter. Measure one side then the other side if the 12 volt is going thru the fuse.

Next step is now you know your amp is getting 12 volts from the car battery but do you know if your amp turn on signal is turning on the amp itself. This is a easy test get a little wire and jump the 12 volt to the amp turn on wire if the amp comes on then you have found your problem. The amp turn on voltage is too weak were ever youve connected the signal. Normally you hook it up to the blue/white wire on the back of the radio first. If it doesnt have one hook up to the blue. Now on some very rare occassions the voltage drops when you put a load to it and is not enough to turn on your amp you can easily see this if the voltage across the blue wire goes below 12volts so hook it up to the red ignition wire so at least when you turn on your radio the red will send 12 volts to the amp to turn it on and will not drop in voltage. You see that wire has to be 12volts when it drops the amp will not turn on. Same with the battery Voltage you have to maintain 12 Volts or higher for the amp to operate.

There is a red blinking light and it is not cleaning.


My Ionic Breeze would work for a short time after cleaning and the blue light would start flashing and the unit would stop working. I checked the wall cube power adapter with a volt meter. It was putting out only 10 volts instead of the needed 12 volts. It seems The Ionic Breeze needs a full 12-13 volts to work. So I went to Radio Shack and bought a universal 12 volt 800ma power adapter. I checked the voltage in the new adapter, it was 13 volts. This fixed the flashing blue light problem. However the Ionic Breeze produces harmful Ozone gas, so I don't use it anymore.

Radio no power which is maching fuse


There are two fuses that power the radio. The 15 amp CIG fuse and the 15 amp DOME fuse.
AT the radio connector, you should have 12 volt power in the GREY wire (this is the main power from the CIG fuse) and 12 volt power in the BLUE with YELLOW tracer (this is memory power from the DOME fuse). If you have power in botrh of these circuits, suspect the radio being bad.

Amp turns off


your radio has 2 blue wires. one of them provides a 12 volt turn on for a power antenna (when a cd is inserted that 12 volt turn on turns off, because when a cd is playing, the antenna doesn't need to be raised up). The other blue wire has a 12 volt turn whenever the radio or the cd is turned on--this is the blue wire that you need to connect to your amp remote line. ( pull out the radio and switch the blue wires)
respectfully,
Merle

12 VOLT FROM THE BATTERY SOURCE GOES TO 12VOLT BATT CONNECTION.12 VOLT GROUND RETURN MUST BE FIXED TO THE FRAME OF THE VEHICLE.SOME VEHICLES HAVE FACTORY GROUNDS UP HIGH ON THE SIDES OF MOST VEHICLES, U CAN USE THIS GROUND LOCATION. IF CONNECT REMOTE WIRE FROM THE RADIOS REMOTE TURN ON LEAD WHICH IS A BLUE/WHITE WIRE OR A STANDARD BLUE IF ITS JUST ONE BLUE WIRE. CONNECT THIS LEAD TO THE REMOTE TURN ON CONNECTION ON THE AMP , SOME KENWOODS HAVE TWO ,INPUT AND OUTPUT LEADS.U ALSO NEED A TEST LIGHT, OR U CAN USE A SPEAKER TO TEST FOR POWER AT UR CONNECTION.IF U USE A TEST LIGHT , CLAMP THE END U WOULD GROUND TO THE VEHICLE, TO THE AMPS GROUND, THEN TOUCH THE PROBE END OF THE TEST LIGHT TO UR WIRED CONNECTION TO VERIFY U HAVE POWER AND GROUND TO YOUR CONNECTION.IF TEST LIGHT DOESN'T WORK ,CHECK UR FUSE AND REMOTE TURN OR LEADS.
