I have a vacuum cleaner which I use in my car by connecting it in the 12 volts lighter socket. In wish I could use it for my Music system at home, is there any possibility that I can use it by some so

check the current draw for the machine and if it is over 20 amps then the socket cannot be used
12 volt sockets for accessories sockets can be got from autozone or other auto spares shops

the lighter socket will be straight 12 volts and the GPS may require less (5.5 volts) and the different size is to prevent the over voltage and damaging the GPS unit. There may be an adaptor that will do the job and it may have a built- in transformer for the purpose.

most likely..or wire in an extra socket..

Hi, you have a 15 amp fuse to run all 3 sockets. Total peak power available without burning the fuse is 15x12=180 watts peak. Please let me know if you have more questions.

Each time you disconnect the battery, the computer loses all codes for security system, radio, etc. If you know the code for radio, enter it into radio using the number buttons. To prevent this again in the future, you should purchase a power cord for the computer. It has the lighter plug on one end and a plug you connect to the car's computer. Plug the lighter plug into any 12 volt plug (not the lighter socket in your car)...you can purchase a portable jump starter with the 12 volt socket. The purpose of this is to keep the car's computer "powered" while you disconnect the battery.

First off,connect something to the cigaret lighter that has 12 volts,and make sure the lighter plug in socket is working,then remove the battery cables and clean the cable ends real good,like shiny clean,and the battery post.It sounds like the alternator is having a hard time charging the battery,and the ignition system requires a lot of volts,and amps just to run,when turning the fan on,the engine revs up,this tells me it is possibly causing the alternator to put out more volts.

Unplug it and see if you have 12 volts to ground on the feed wire. Need a Volt meter

Might have gotten a short in the wires somewhere. Pull your center console up and see if both ground and power is connected to the cigarette lighter.

The lighter elements go bad a lot, you can get them at any auto store. If it's the socket (The female part), and your navigation doesn't get power from it, you can also replace it if it looks rusty or damaged. First make sure your fuse is good to it. If yes, you need to get at the socket where you will see two wires connecting to it. One is a ground, and the other is positive from your battery. If you have 12 to 14 volts between these, your socket is bad!

Hi, grab a voltmeter and test volts at car lighter connector, near to car lighter socket, if there is volts in there (uncommon) , then check for short or broken contact on car lighter socket, or replace the first socket connected in line.

If there is no voltage getting to cig lighter, check the two connections at the back of the fuse box, on the cigarette lighter fuse.

If there is volts only on one side, then fuse is gone again, in that case there is a short on wiring, maybe on one of lighters, locate it and fix it.

If there is power on both sides of the fuse, then fix or replace wiring between fuse box and cigarette lighter, one wire is broken.

If there is no power on both sides of lighter fuse, then fix the wiring between fuse box cig. lighter contact and battery, if this is too complicate you can even build a new wiring and solder in place of the old one.

If the lighters have more than one fuse, do the same job for both lighter. Cig. lighters do not use a relay, and there is no additional fuse, the above procedure is enough to fix any possible problem on such a simple device.

If you have no practice with this kind of repair on car electrical system, then better to go to a car electrician or mechanic rather then messing up the car electric system.

Please do not forget to leave us feedback afterward, that is important for us.

Many thanks.
