I have my satelitte radio plugged into my car lighter it stays on when cars off y???

Question

my satellite radio has static and stays on after i shut my car off. Does it have something to do with the car lighter it is plugged into? the static goes away when i hold the receiver in my hand also. This didnt happen in my other car only a new truck i bought.

Answer 1

Check your owner's manual for the truck. You can change the settings for how the lights, lighter plugs, etc. behave once you turn the car off. Your setting may have been defaulted to keeping the lighter energized. This can usually be changed by a combination of your ignition key turns to the on/off position.

As for the static you may need a direct connection from your satellite receiver and your truck's radio. In some vehicles the signal from your receiver to eht vehicle radio get more disrupted than others. You can purchase the direct connect cable to hardwire the unit. It is a pain but it will definitely get rid of the static.

On an easier note. Try changing the FM station that the satellite receiver uses to bradcast. You may be using a signal that it too close to a strong FM signal. Good luck.

Some cars when you plug things into the lighter it takes a couple Min's before it shuts off or it might not at all but as far as static but none when you hold it in your hand well you could be picking up interference for anything in the dash or where ever you have it mounted so just try mounting it some place else is just wondering did you buy a ford cause the power to my lighters does not shut off at any point and seems to be a problem for them but if it is guess you just learn to plug it in and unplug it when you get in or out but if it is a ford at least know your not alone

Answer 3

The lighter power isnt on an ingnition switch. Its just constantly wired. You can rewire it, so its on an ignition switch if you want. Just find the power wire that your stereo is on, tap into the positive, so then the lighter will shut off when the car is turned off.
The static can be fixed by buying something called a ground loop isolator. You then have to cut the negative wire on the lighter (if you dont want to rewire it) hook up the ground look isolator, and this will take care of the static caused by other electrical components (more then likely your fuel pump is to blame)

Answer 4

sure, you'll favor to plug your sat. radio right into a cigarette lighter to artwork. No electrical energy will be presented by the cassette adapter. As a caution besides the undeniable fact that...I "tried" to be sensible with mine and cut back off the cigarette lighter section and puzzling stressed out it into my motor vehicle behind the sprint to target to make it seem sparkling. i did not keep in mind that those radios are like 3.5 volts (or some thing like that) and my 12 volt equipment fried it. The cigarette lighter portion of it has the stuff mandatory to step it down. As a education...bypass to walmart, or some position similar, and get a splitter on your cigarette lighter. then you definitely can hook that into the wiring behind/below your sprint, plug your radio into that, and also you'll have a sparkling seem that isn't fry your unit the first time you narrow back it on.

Answer 5

Sounds like a grounding problem. You need an inline filter something like the little buddy listed below. You will probably need to work with a local auto sound shop to get the right parts. The second link is a site that sells the actual filters these kind of shops usually employ to solve these problems.

Answer 6

The cars ignition (being on or off) has nothing to do with the lighter . . . that is connected to the battery & is always on / so things plugged into it can drain the battery.

Answer 7

Just because your car is off, as long as your radio is connected to the 12 VDC source...it will remain on. It's using your car's battery as a power source, and that won't change just because you turn your ignition off.
