Ford Fusion Cigarette Lighter: Re-wire to Turn On and Off through Ignition?September 4, 2013 4:44 PM Subscribe

You are watching: 2011 ford fusion cigarette lighter fuse

I have a 2010 Ford Fusion and also a lot of electric gadgets which plug into the cigarette lighter. The automobile I previously drove (for over ten years) had a cigarette lighter which turned itself on and also off with the ignition. The Fusion, yet, leaves the lighter socket on all the moment. As such, I sometimes forgain to unplug points from the cigarette lighter and finish up with a dead battery after a day or two with the automobile parked.Is tright here some relatively-simple way for me (or a mechanic) to re-wire the cigarette lighter so that it powers itself on and also off through the ignition? If so, how?
*** Pre-emptive answers to questions you could *** 1) Why do not you just remember to unplug your stuff? Probably bereason the automobile I drove for the previous ten years didn"t require it. I have actually had actually this car for simply over 3 years and also I still forobtain to unplug points from time to time, so I need another solution. 2) If you"ve run your battery dvery own this many times, it"s probably swarm. You have to buy a new one.Yeah, I know. But I don"t desire to buy a new battery simply to run *it* down repetitively because of my lack of remembering to unplug stuff. 3) Your "stuff" shouldn"t run your battery dvery own in simply 1-3 days; somepoint is definitely wrong via your battery/car/and so on..I have had my battery tested by both the Ford dealer and also independent auto parts stores, and they say nothing is wrong via it. Additionally, as soon as I do remember to unplug all my accessories, I deserve to leave the auto parked for over a week and also it starts simply fine afterward.4) What the heck sort of stuff execute you leave plugged in that reasons your battery to run down that quickly??My Garmin GPS is enough to make it run dvery own in 2-3 days of being parked. In enhancement to that, I sometimes also run a cell phone charger and a Globalstar satellite phone from the car power. *** End Section *** I am familiar with and also comfortable working through 12V electronic devices. I would certainly prefer to carry out this job-related myself, however would most likely refer it to a mechanic if it calls for substantial removal of dashboard/etc components.Thanks in development for your suggestions!

Casual googling says that there"s no "stock" method of doing this on the Fusion (e.q food selection setting or seekrit OBDII handshake.) My approach would certainly probably be to find a 12V line going to the stereo that is ignition switched (the stereo turns off once you rotate the car off, right?) and use that to communicate a relay that interrupts one pole of the cigarette lighter. This would be safer than rewiring the cigarette lighter to directly steal present from the stereo or one more adjacent ignition-switched circuit that might not have actually the spare capacity to charge all your devices without blowing a fuse or worse.I think this would certainly be trivially easy for a automobile stereo shop to achieve.posted by contraption at 5:05 PM on September 4, 2013 <2 favorites>
It will certainly more than likely better to tap into an 12V accessory wire that loses power as soon as your automobile is off than to try to modify your cigarette lighter. If not, you may need to find a fusage that is accessory hot and also run it from your engine compartment.posted by wongcorgi at 5:06 PM on September 4, 2013 <2 favorites>
What contraption shelp. You have the right to pick up any kind of SPST relay for a few bucks and wire it up yourself.The accessory circuit will certainly drive the switch in the relay, and the relay will drive the outlets. Make certain you get one that have the right to manage 10-15 amps at leastern. Pretty much any auto-component save will have actually them.Additionally, you might wire a SPST switch in tright here, but finding one that have the right to manage the max draw of the outlet (10 amps, probably, but as high as 15) will be harder than finding an tantamount relay.posted by Pogo_Fuzzybutt at 5:55 PM on September 4, 2013 <2 favorites>
Yeah, the specific solution would be to put a relay in the cigarette lighter wire. Right currently it probably runs more-or-much less straight to the battery, so that it can supply most present if you had actually an actual resistive cigarette lighter in there (which virtually nobody actually does anymore).However, the less DIY solution would certainly be to obtain somepoint like a "PriorityStart" or various other "battery protector". Basically they are little bolt-on accessories that go on the battery and will certainly shut off existing if they detect the battery obtaining low. You commonly need to pop the hood to recollection them, but they store you from running the battery dvery own low enough that you can"t start the vehicle. They are very straightforward to install and result in no long-term adjustments to the auto.posted by Kadin2048 at 6:16 PM on September 4, 2013 <1 favorite>
There likewise might be a spare switched fusage bay in the fuse box. I seem to remember those existing on some cars. So you"d just uncover the wire that goes from the accessory/lighter socket, remove it from the lug that it is presently attached to, connect it to an empty one and also insert a fusage. Or simply install a brand-new switched socket, leaving the original ones as equipped from the manufacturing facility. (According to the owner"s hand-operated, tbelow are numerous spare fusage locations, so one of them have to occupational.)I wouldn"t mess through relays unmuch less you had actually to. Just another point to fail.tennis2007.orging another question: does your auto have actually multiple accessory/cigarette lighter sockets? I likewise seem to remember that more recent cars would have actually more than one, and various ones would run off of various resources. (Never before mind, I just checked the hand-operated and also it doesn"t appear that there is one.)Anvarious other option: does your stuff have a sleep mode? I deserve to understand the GPS unit running down the battery after a number of days, however the phones shouldn"t run it dvery own. So if you have the right to collection the GENERAL PRACTITIONERS to shut itself off after 4 hours or something, that need to work-related too.posted by gjc at 8:01 PM on September 4, 2013 <1 favorite>
Pretty much what gjc is arguing - I found a spare place in the fusage box for somepoint that just comes on via the ignition (heated seats or something not fitted) and used a cut dvery own spade connector shoved into where the fusage would certainly go (through an inline fuse (fairly important)) to a replacement lighter socket. For 0v you just must make a great link with metaloccupational. It"s not super slick but it"s removable in seconds.This all relies if you deserve to acquire quickly from the fusebox to somewright here convenient for your electronic devices of course.posted by samj at 11:22 PM on September 4, 2013
Would you be willing to pay $25 for a cable that instead gives power from the OBD-II port? The OBD-II port is always on, yet I recognize that a special cable is in the procedure of being emerged that would certainly just output power to your devices as soon as the engine is on (it does that by making use of specific information from the OBD-II port to know the operating condition of the vehicle). Something equivalent can be done through the cigarette lighter plug by measuring the voltage (a drop in voltage would be a proxy for "engine off") however it would most likely be less precise.posted by Dansaman at 10:38 AM on September 5, 2013

Response by poster: tennis2007.orging one more question: does your automobile have actually multiple accessory/cigarette lighter sockets? I likewise seem to remember that newer cars would have even more than one, and also various ones would certainly run off of different sources.It does, but they are all always-on; namong the power points are ignition-switched.posted by Juffo-Wup at 5:11 PM on November 6, 2013
