12v

I have a 2004 W209 270CDI and am having trouble with the accessory socket, it is the optional 12V one, not the cigarette lighter. Nothing I plug in to it seems to get any power, yet if I put the meter across it there is 12V present in the socket. Are these sockets different and don't work with...

My car has just been in as the a/c system failed due to blocked channels causing water to get into the electrics of the system (I think) and looks like they had quite a bit of a job to sort it out, pulling half the passenger side dash out etc. Anyway, since I have had it back, when I use the...

Hi! As many of you know, I was quoted £200+ by main stealer foe extra 12v socket in boot of my car. Bit excessive if you ask me... For £50-60 I wouldn't even bother checking what needs to be done but £200 it's a different story. So, today I went to my mate and here it what we have done :) It...

Hi The 12V socket is not powering either a mobile charger nor DVD player chargers - when it used to - so I am guessing its the car. So, after finding the correct fuse (from a quaint piece of paper in a fuse box) replacing a "15" fuse with one from the spares which have never been opened, so I...

At the weekend i am going to fit a charging cradle for my phone. I have done it a few times on lesser marques, but not so sure on this car of where to start. If anyone knows the best place to get access to a 12v supply (permanent or ignition live) on the passenger side (and what panels to remove...

I changed the plugs the other day, first the autofactors gave me later car plugs with gasket. Then I got h7dc bosch ones. I removed from the car hr8dc plug's. The car now seems to run a little lumpy, should it have in h7dc, h8dc (gsf suggestion) or the removed hr8dc?? I understand from reading...

I'm rewiring the rally car, and I realised I forgot to make notes of where some cables go... Are the lighter plugs/12V sockets in cars positive core or positive shroud? I have both options, and don't really want to guess :p Thanks, M.

Does anybody know where I can pick up a constant live on the back of a comand 2.5 unit? according to the diagram I have its pin 5 block A, but this seems to be CANBUS controlled and shuts off after about 20 minutes. Confused to say the least would anybody have any ideas?:crazy:

Getting close now with my IPOD integration project. The Harman and Kardon unit has three wires for power. a Red marked ACC/Ignition Switch, Yellow marked +12V dc and black marked GND. The yellow and black seem straightforward but I am unsure what the red one is for. My plan was to take the...

I need an unswitched 12v supply in my boot rated at no more than 1 amp. In the rear fuse box theres a few spare ways and one of which ive found has a permanent supply, on the rear of the fuse box its numbered 5 and coloured green but this does'nt correspond with fuse 5 on the front.My fuse...

Does anyone have access to the wiring diagram of the R230 SL? I need to get a permanent +12V feed from the wiring harness at the passenger footwell (pic below) to install a module for the vario roof. So many wires, but which one(s) do I need :confused: Help!

Looking to pick up a switched 12v + & - feed to hard wire a sat nav mount in my 2008 E 280 CDI Sport. Looking to access the back of the cigarette lighter. How do I get in there? If there's an alternative source I'm open to suggestions. I don't want to have to plug the fag lighter in every...

Hi I changed my battery and had to remove the radio to get the code, when refitting the radio it would not switch on, on investigation the constant 12volt feed is dead at the plug I have checked all the fuses and all are ok Any suggestions Regards Barry

Hi, Could anyone point me to how-to make an 12v socket in boot which is always ON? I've seen fuses so it shouldn't be to hard to do. I was quoted over £200 by MB stealer just for labour... :devil: I'm sure that I can connect one of those splitter somewhere... Cheers Chris

Hi, I am in need of a power source for PDA/Phones on the driver side dash. Attached is a picture of a magnetic mount that i bought the car with. It is just below the Parrot bluetooth. Its the Grey Rubber Circle. Is there any way i can access a 12v connection to power up the PDA/Phone on...

Recently bought a Cheetah GPS Mirror and would like to hard wire it into my ML. Can I get the power from the overhead light console? If so, assume that this would be a continiously live 12V. Where is the 'closest' or easiest place to take a switched 12v from. Would it be easier to take the 12v...

hi i need to wire in my towbar auxilary feed (for the fridge electrics etc). anyone know the best/easiest place to tap into an ignition 12v feed in the boot area of a W124 estate? in addition to this i have considered adding a cigarette lighter socket to the rear of the car (to plug in...

When we did Paul's (JpsKiller) 3ltr Head Gasket we decided to do a howto. Its rather long so please be patient. I won't be able to complete the thread in one go as there are 40+ pictures and descriptions to go though. In the beginning take one 3 ltr engine and notice the oil sprouting from just...

Has anyone here purchased and used one of these 12v impact wrenches and are they worth it ? Seems like a good gadget but then, how often would you use it ? http://www.autoexpress.co.uk/products/products/217677/impact_wrench_test.html
