    Unexpected ??Fault??

    Hi All,

    I finally got around to wiring my footwell neons today with an unexpected result.

    Firstly when I say neons I actually mean CCFL's.

    Below is a diagram of how I did it:




    Also although I'm aware you wire the poles of the 3way rocker to the opposite side of the position you want, for ease of diagram and explaination I have just labelled them and will refer to them at the positions shown in the diaram.

    Now when the switch is at position II the lights come on - as expected.

    When the switch is at position 0 the lights are permenantly off - as expected.

    When the switch is at position I the lights come on when you unlock the car, along with the courtesy light, and fade in time with the courtesy light. They also turn off when you lock the car as expected, and also turn on when you open the doors as expected.

    All sounds very predicatable. I stood back and admired my handy work.

    I left the switch at position I as is my intention. Now when I just went to see my mate, when I started the car I found that the footwells turn on with the headlights??
    They dont fade over time and the only way to get them off is to either put the switch into position 0 or to turn the headlights off - neither of which are ideal for what I was trying. I want to leave the switch in position I pretty much all of the time and not have to turn to 0 everytime I need to use the headlights??

    Any ideas? If it matters, I have AFL with the sight and light pack - and remember they are CCFL not neons.

    Thanks for any advice.

    I'm going to guess you have the interior light with the indirect lighting in it that sends a dim light out of it when the headlights are on? (sorry don;t know what it's called) I also guess this light comes on with the doors open and the lights off

    The wire you will need to go to is a grey one at the interior light but this is negative switched

    EDIT:

    To rewire this your just going to have to rewire it all the opposite way round so the neons have the permamant live, the earth goes to II on the switch and the grey interior light wire goes to the ! on the switch then the neg to the neons to the O on the switch

    Hope that makes sense

    Thanks for your quick reply. The courtesy light is the type with a central light and 2 lights either side of it which only come on when switched. The central light does come on and off with the doors and when you lock/unlock the car. I can't say I've ever noticed that it illuminates (even dimly) with the headlight on though.

    So basically you think to wire the switch with a permenat earth and the grey earth from the light with the neons wired to a permenant live instead of wiring the switch with the lives?

    Thanks again.

    My friend you have done a good job to tackle this but unfortunately my friend you have use the wrong wire :P

    The idea is correct your method is working, you just messed up and used the wrong wire.

    diconnect the wire in port I and replace it with another wire which will power the interior light, i believe it is a red and blue wire (runs along the side of the car)

    That will solve your problem

    Also you#'ll need to change your positives and negatives.

    Have a read in your owners manual about the "Automatically regulated centre console lighting", it's on page 113 of the manual i'm looking at here. This is the lighting i'm on about that you may have. I don't own a MK5 though so don't know anymore about it

    Yep thats the way to do it

    EDIT: Steve is the red/blue not permamant live though so won't switch off when the doors are closed?

    Thanks again for your help - some remedial works needed then

    Thanks also Steve but I tested the red/blue and it is a permenant live so would not fade with the doors etc.

    Never knew anything about that regulated lighting thingy, will have to have a scoop at my manual.

    Cheers

    sorry guys updated my post, forgot to mention its a variable earth so you need to change your live and earths.

    Hi Steve,

    I thought the red/blue it was live not an earth so that wouldn't work would it? I'm thinking like autosparks, if you change your diagram and replace the red/blue with the grey from the courtesy light - i think that will work?

    Forgive me for being a bit thick, but if the grey at the courtesy light is earth, then will the lights not permenantly be on by wiring to it? Or is the grey a variable earth, that only actually goes to earth when the doors are open etc?
