Technical Cigarette Lighter Mk2

[SkyB]

Hey Guys and Girls.

I Recently Bought a Mk2 Fiat Punto, Although ive had a few problems with it its been great.

I just need some help though. I recently bought an Ipod Fm transmiter only to discover that my Cigarette lighter was Broken.

I went straight to halfords and Bought one (it looks like this)

I followed the Guide on the forum of how to take the Centre console off only to discover that the Cigarette lighter that halfords claimed would fit my car actualy wont.

Ive taken a picture of what the Lighter in my car looks like ....

Would be great if someone could give me some advice here. Cheers

I do not understand your problem.

You are showing the elctrical end of your existing unit.

Does the Halfords one physically fit in the hole?

Are you sure the lighter is at fault, not the supply?

Have you carried out a circuit test?

Cheers

The Problem is Deffinatly The Lighter.

If you look at the two lighters then you will see the ends are both different fittings .... All i really want to know is if there is a way to conect the new one.

The existing wires all go into a little white plastic box which then plugs onto the back of the existing lighter ... but it doesn't fit the new one.

Just nip to your local fiat dealer they will help you .. they should have a tester and that .. or halfords and just say i bought this why wont it work ... they will help u cuz they know they will probly get money outa it haha

i got one of the fm tansmitters too and mine doesnt fit into my lighter correctly, it wobbles around in it and only gets a connection sometimes, is this the problem your having? i was going to buy that same replacment so if you could tell me if you gety it going that would be great ?
thanks

My Fm Transmiter fits fine into the old and the new.

The Problem is that the conection for the new one is Different. I may pop over to the Fiat dealer next week.

probably good idea, but their extorsionate.

Hyia mate the conecter on back of ur original one will be a fiat one all ull have ro do is snip wires add spade connectors on the back and plug in the one u bought is universal so u cant expect it ro have the same plug as they then would only be able to sell it to fiat owners only

Ah, As Adam suggests, adjust the wiring to suit.

The centre pin is the live one.

Thanks for all the Help Guys

I have 3 wires going into a little white box that plugs onto the back of the old one.

I have Yellow, Red and Black ....

Which should go to the centre and which should go to the outside Pin ??
Also as theres 3 what do i do with the spare wire ?

Cheers
P

P.S im Not to worried about wireing in the Light.

You have three connectors on the new socket.

I think red is power live and yellow is controlled, but do check with a test light first.

Red/black is supply for the lamp
Yellow/green is 12 volts for centre pin
Black is earth for outer

red

 

[SkyB]

Mabey its easier if i take a Picture ?

I ONLY have three wires,

Yellow
Red
Black

P.s Reading you Post Could i Use the Yellow and the Black i have ?? Im not to Worried about Having the Light Working.

You have three wires on the plug you are about to cut off, and you have three connectors on the new lighter.

Use a test lamp to work out which wire from the plug you need to attach to the lighter. Do not leave a bare wire hanging, wire up the light.

Have you confirmed the new lighter physically fits in the hole left by the old one, as ypou don't want to go cutting plugs off and find out it doesn't fit.

Do no believe the term 'universal'.

My reference to red/black and yellow/green meant red with black tracer and yellow with green tracer.

I'd go for:

Black = earth (outer)
Yellow = 12 V supply (centre pin)
Red = supply for lamp

I'd disagree, which is why I suggested the OP get the test lamp out to make sure.

SPD Im no Electrition ... whats a Test lamp when its at home ??

The other thing is i have 3 wires as we all know. Yet my Lighter needs 4

For the actualy power i need the 12V and the Earth, Ive got that.

But for the Lamp i need two wires as well.
I Currently have a red and a black that are already inplace for the lamp which cannot be removed.

So i kinda Need to know what i should do.

Sorry for making this so long winded and cheers for the help guys

Hmmm...

My first statement regarding colours came from Haynes for Mk2:

Pin 1: Red/Black, lamp supply from Fuse F51, 7.5A
Pin 2: Yellow/Green, 12V supply from Fuse F44, 20A
Pin 3: Black, earth

I thought I'd better cross-check with Fiat's DTE manual. Pins 1 and 2 are reversed and a different fuse is cited:

Pin 1: Yellow/Green, lamp supply from Fuse F21, 7.5A
Pin 2: Red/Black, 12V supply from Fuse F44, 20A
Pin 3: Black, earth

So, both sources concur that black is the earth. The worst case scenario is that the other two are crossed, causing the socket only to have power when lights are on, causing its light to be on when it shouldn't and probably blowing fuse F21/F51 (whichever it is) if something needing more than 90 watts is plugged in.

Note that neither reference shows the single colours that SkyB has.

SkyB, you can test it out thus:
You can presumably identify the two wires for the lamp on the new lighter (you say there are two wires in place for the lamp, red and black, presume you mean pre-wired to the lighter). Use this as your tester. Connect black to the black in your loom and red to the red in your loom. Now switch the ignition on and see if it lights up. If it does, the loom red is your 12V supply. If it doesn't, switch your side lights on and it should light up. Now you've decided whether the loom red is supply or light. The loom yellow is therefore the other one (you can repeat the test with lamp between loom black and loom yellow if you want to prove it).

You say you need four wires. This is because the lighter and its lamp both need an earth. You'll need to join both of them to the loom black (black from lamp and wire from lighter outer). The 12V supply (you worked it out above) needs to go to the wire for the lighter centre pin. The lamp supply (you also worked it out above) goes to the lamp red wire.

That's a bit long winded ain't it - does it make sense?

red.

Pin 1: Yellow/Green, lamp supply from Fuse F21, 7.5A
Pin 2: Red/Black, 12V supply from Fuse F44, 20A
Pin 3: Black, earth

.

That was my thinking.

I hope the OP has got his head round this. The current available from the lighter supply is enough to toast the car.

So your Saying that i use the Light on the lighter to test which is which. Got that.

Then i just need to wire it correctly and use the same earth for both

Il Give it a Go.
