I hoovered up my car cigarette lighter and the next day my battery was dead, are the two connected?

Answer 1

It's very unlikely that the two are connected unless something got dropped into the lighter outlet... if a small piece of metal were to fall in there it could cause a short and drain the batter - but this is very unlikely... you should have a mechanic look over your car's electrical system if you have no idea why the battery went dead. You may have a bad alternator ($150 - $200) or a bad battery ($50 - $125).... or maybe you just left your parking lights on.

Answer 2

If its a trick question - yes the two (battery & lighter) are connected!

If its not a trick question - Its highly unlikely that hoovering up the lighter caused the battery to go flat.

And don't bother trying the test lamp on the negative lead thing - If the lamp DIDN'T light up it would mean you'd have quite a few bad circuits..... certain things are always on and always draw a current (all be it very small current) eg. clock, radio memory, etc.
So the bulb should always light up!!!

Much better to start with a test meter on the fuse terminals....
then check the alternator output & battery voltages (both charging & "static")
So get a decent mechanic / vehicle electrician to check it over...... it might be just time to get a new battery - they are only good for an AVERAGE (I know SOME last lots longer!!) of three or four years for most cars..... and its this time of year they start to fail due to the higher daily drain & re-charge caused by lights, wipers & heaters

Answer 3

Of course your car cigarette lighter and your car battery are connected. Usually, the lighter is directly connected to your battery, meaning, it does not pass through your ignition switch. That's why you can still light your cigarette even if the ignition switch is off. When you push the lighter to each casing, the electrical circuit is completed and your lighter lights up. Then at a certain temperature the lighter is ejected from its casing, That's when you pick up the lighter to light your cigarette.

I'm inclined to believe that the lighter is not the cause of the "untimely death" of your battery. There must be some sort of "weak" short circuit somewhere along your wirings. Because assuming, you left your lighter pushed into its casing, and the lighter did not eject at the designated temperature, its heater will continue to burn. In that case, you would be very lucky to see your car intact the next day.

I suggest you get a competent auto-electrician to check the electrical system of your car?

Answer 4

Yes the hoover does use your battery for power. In theory it shouldn't drain the battery BUT I believe that those hoovers can be 'dodgy' as the last time I used mine my car failed to start after!My friend who is an electrician wonders if the hoover might cause an energy surge. My advice is to avoid those hoovers!!

Answer 5

Only if you were wearing purple trousers last Thursday.


Sorry, I thought this was a joke!

The cigarette lighter is not using power from the battery unless it's plugged in so there's hardly any connection there. I keep my lighter in the glove department because I charge my phone in the car so the lighter is never plugged in and I never have problems with he battery.

Answer 6

What does "hoovered up" mean?

Perhaps your battery just "gave up the ghost".
Perhaps your alternator wasn't charging the battery and it chose that time to go dead.

ANY "dead short" across something like the cigarette lighter socket contacts would cause the wiring insulation to burn off causing lots of smoke, fire, running and screaming.

Did the battery charge back up? Did it stay charged? Did it go dead again? Good luck. Pops

Answer 7

Jesus! there are some crap answers up there! no you hoovering up your cigarette lighter did not cause the battery to go flat - it may be a weak battery - you may have knocked something on when you were cleaning or left the radio on when you were finished?!

Answer 8

yes they are connected if u feel you have to have a ciggarette light and want it to work witout draining your battery hook it nto your radio power wires they go through your ignittion switch first so it will only work if the car is on u know it may short out the fuse though if u know how to wire things u can use a circuit that runs through the ignition first u just have to find a circuit and then hook it up to the back of the fuse box make sure the lighter doent pull too many amps or it will blow fuses constantly

Answer 9

if you hook up the lighter without the lighter push in,it should not drain the battery.something else is draining your power. try this method.disconnect the negative battery cable.using a test light,hook one end of the test light to the negative battery terminal.hook the other end of the test light to the negative battery end.if the test light lit for 15 seconds or more,this is why your battery is dead. to find out which system is draining your battery,start disconnect one fuse at a time.if you pull out the fuse and the test light go off,that is the system that is draining your battery

Answer 10

I am not sure what you mean by (hoovered up) but yes they are connected. The battery is where the lighter gets power.
