Hey guys, My cig lighter has been causing problems i think, Before the lighter would only work if the headlights were turned on, which i found weird but never used it so i left it. Then the other day my cig lighter became loose from its socket so i tried to see if there was any loose wiring but could not see anything wrong, but i dont know what the heck im lookin at anyway.

Now after the cig lighter became loose from its socket the parkers, tail lights, dash lights stopped working. I replaced the lighter fuse which was buggered but it did not fix my problem. I replaced a burnt out tail fuse and the dash lights came back on, when i went to see if my cig lighter was working (which it wasnt) the dash lights/parkers did not come back on. The tail fuse that i just replaced blew immediately, I replaced it again but this time i didnt touch the cig lighter, i only switched the dash lights/parkers on and u betcha the same new tail fuse blew again.

Does anyone with an ounce of electrical knowledge better than mine know what might be the problem?

I supplied a pic in case theres something obvious im missing, the arrow shows the fuse that keeps blowing. Im thinking i might need a auto electrician to maybe fix my cig lighter thats fkn things up??

The cig lighter is a common place to draw power from for boost controllers, boost gauges etc, might be worth looking to see if a previous owner has done this and messed with the wiring somehow.

does your cig lighter have a white ring around it that illuminates when lights turned on?? that wire might have come off. otherwise if it only worked when lights turned on, prob wired up wrong. prob still need to just pull that panel out and will be visually obvious.

i work at delta autospark in redcliffe, if ur free during the day we can check it out but it'll prob be much much cheaper if i did a cash job for ya, im busy 2mro i can have a look wednesday afta work. ive gota drive to alexander heights to get home so im onli realy SOR after work (round 5ish).

the cig lighter will have an acc feed and and earth going into the back of it and a park light feed going into the side of it.

i cant tell you why it was only working when ur headlights were on that sounds really strange unless some retard gave it a headlight power feed (cant understand why)

the actual element might be all loose right inside the socket and shorting out, and cigarette lighters are usualy all pretty universal and cheap (atleast it'll rule that out)

or theres a short in the wiring the first place to look would be behind the cigarette lighter.

pm me if u want me to have a look at it

All dependant interior light (dash cluster, dash switches, climate control, glovebox, auto shifter) are all on the same circuit as running lights/park lights.

This is why it would only work when you're headlights were working (power is meant to be independant to illumination, read below)

its possible that the power for the cigarrette lighter is feeding off the illumination for the ciggarette lighter.

An intermittent breach in the circuit would explain fuse blowing only in specific circumstances. Brake lights will work, as the brake light circuit lights up both filaments anyway, headlights will work, but no park lights, and you wouldn't have interior lighting.

there are two harnesses going into the cig ligher.

the one in the middle is actually for illumination, and the smaller one beneath it (which you would THINK is for illumination) is actually for power) its common for connectors for either of those to snap easily. Check the wires within say...one metre, or if you can, trace them all the way to the fuse box, and see if they've been crossed over.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
