Today i noticed my front LH light was out, so i changed the bulb, still didnt work, so i realised the fuse was blown, easy enough 20 cents later problem fixed

Driving home at night i noticed that the cluster backlight wasnt... well, backlit PROBLEM 1

Then i took the car in to the self wash and started vacuuming, i turned on the lights and noticed that on the first setting and nothing, no lights, then when i look at the back of the car, the rear lights arent on either? - PROBLEM 2

Then i put it on the last light option (the top one, u kno) and the front lights work, but the back lights aren't lit up.... ----BUT when i put my foot on the brakes, they work, but only when i have my foot down... so they do work, but there must be something up

HELLLLLLLLLLLLLLLLLLLLLLLLLLLP

lol

Headlight switch here: http://www.skylinesaustralia.com/forums/in...howtopic=115618

Your switch is stuffed as T04GTR said. There are three contacts within the switch. As you rotate the headlight dial on your dash, you change which terminals are touching the contacts, therefore changing the lights.

The contacts do not move in an incremental/accumulative way - that is, if the contact for the parkers/dimmer is stuffed, you can still switch to the next one and your headlights will come on. Think of it as though each time you click the dial, the switch is telling your lighting system to switch on/off. When you click to the next one, it send the next set of orders to your lights, but doesn't repeat the first set.

I know it's a weird explanation but that's where your problem lies.

Azza ring Just Jap in Sydney and they'll sell you a switch for ~$50. You can try fixing yourself too if you're keen on DIY.

And finally, there actually isn't a relay in the switch and therein lies the problem. The switches burn out due to excessive current melting the plastic pots within the switch. The only way around it is to rewire the switch to trigger a relay and use the relay to activate your lights.

Cheers dude! :D

Sounds strange to me. Before you rush out and buy a new switch double check that the same fuse isnt blown again. All those things run on the same fuse. If there is a short somewhere it will continue to blow the fuse. The reason your brake lights work is because they aren't on the same circuit.

If your LH light was out, im assuming parker light, why would only one of them be out if the fuse was blown? The whole circuit would have failed, therefore all of lights on the same circuit wouldnt be working.

Then again it could be the switch.. You could test it for continuity.

G'day Azza. Sorry mate, been out of town for a few weeks. Don't worry about the beers, cause I sure owe enough around the country :D I hope you sort the lights painlessly.

The switch is the same in all R32s, so swapping your bro's switch would be a cheap way to test it out. The switches are a well known cause for LH headlight failure. You can tell it is starting to go when you switch your lights on and only the RH comes on until you click on/off again or give it a hit Fonzie style.

As Deren said, good idea to check your fuses but I'd be surprised if any had blown.

Could you please report back when you've sussed it out?

      RB gearbox options

      What makes you say CD009 boxes are not as strong as you would think? I've always been told the last revision (CD00A) is good for 1000whp and I have no issue's believing it when comparing one side by side with an RB25 box. Makes them look tiny.

      Nismo 1.5 way Stub axle issue

      I picked up an open Center with shafts. I was told the Open shafts will fit a mechanical LSD and looking at them. I think they will work. Will update

      Nismo 1.5 way Stub axle issue

      By OO Dan OO · Posted

      The manual says a lot about the different ratios requiring different shafts. all the Centers are the same but depending on the ratio, this determines the shafts because different ratios need the center to be offset more or less or right to left.

      those 2 sets of shafts will not interchange and if you’re lucky you haven’t damaged anything with all your pressing and bashing you said you’ve done

      Lets play a game - What is causing my oil consumption?

      By TurboTapin · Posted

      Freshly built stroked RB25/28. Motor runs great but consumes a lot more oil then It should. This summer with the heat I was consuming roughly a quart per 1800-2000kms. Now with the cold weather coming in, I'm consuming a quart per 1000kms which is no bueno. I had originally chalked this out to break in taking a little longer then it should, but I'm now around 4000km's on this engine. I think it's fair to say something isn't quite right. Here's the kicker, can't find what's causing it. I've also spoken to my engine builder and Precision Turbo and can't figure it out. Here's my train of thought on possible causes and what I've done.  Precision Turbo - I originally started thinking my oil pressure might be a tad too high for my 6466 Gen2. I took the center cartridge out, and while yes there's signs of oil on the turbine heatshield, it's very moderate. There's also very minor in/out play that concerns me. I sent pictures and videos to precision and they said the residue and in/out play is minimal and they doubt this is the issue. For piece of mind, I went ahead and installed a Turbosmart OPR V2 to bring oil pressure down. Made no difference. Precision is willing to take it in on RMA for an inspection and I'll probably take them up on that offer for peace of mind. BTW. Is it just me or does the turbines inducer's look clipped and not even between each other? I just noticed this now while posting and looking at the picture zoomed in. Might just be the picture...  Rings - Hot compression test and leak down test look good. Compression is 160 +-2psi across the board. I leak down at 16% on cyl 1,2,3,5,6 and 18% on cyl4. Keep in mind I have a snap on leak down tester and they read high (I.E, 15% on my wifes 2018 Sentra with 70000kms). Sparkplugs show minimal oil (Only #4 seems to have a tad). At a quart per 1000km's though, I would be expecting them to be wet. Here's the kicker, I run WMI. I'm thinking what if my compression rings are great, but I have an oil control ring issue on cyl4 and my WMI is steam cleaning the pistons and sparkplugs? I can still see the "Spool" logo on top of my CP pistons. The only time I see smoke out of the exhaust is in the high rpm/load range. So far, this is my main culprit. I'll probably turn off my WMI and go out with the car at spring pressure tomorrow and repull the plugs. Other thing that's strange though is that I have never seen any oil in my catch can. Thing is still dry after 4000kms. Cyl1 - Left, Cyl6 - Right. Valve seals - They're new and I would expect oil consumption on idle, first cold start or during decel. None of which is happening.  Crankcase pressure - I have 2x 10an valve cover lines to a vented catch can. Head drain and opened up internal oil drain paths. I also don't run E85. I've never seen any oil in my catch can. Doubtful this is causing any issues.  Rear main seal - I have no visible leaks, but figured maybe it was my rear main seal. After now having added 2-3 quarts, I would expect oil to leak out the bottom drain channel and/or my clutch to be slipping.  Let me know your thoughts. With winter coming and taking the car off the road until spring, I'm fine with pulling the motor apart but I would hate to take it all apart and the turbo was the issue in the end.
