There is a little black plastic pack on the back of your alternator. It is full of diodes. Diodes that are usually broken - causing all manner of electrical mayhem. Have a look inside and make sure they are still in one piece. Cheap to fix though - give it to an auto electrician to sort, or look for another 2nd hand one in better shape.

That will be the bulb-check relay turning on, due to a charging fault.

That relay gets it's earth via the alternator, so once it starts charging, the earth is lost.

If you get a 'xmas-tree' on the dash with the engine running, you can consider that it's kind of a BIG charge light!

Yep, all the dash warning lights come up when the alternator is stuffed.

Wouldn't bet on being able to repair this "black box" on the back of the alternator, alot of nissans have an internal regulator which involves disassembling it to have it fixed.

      Got the passenger door on plus the master cylinder and booster. Loaded up to take it home. At home, the colour changes a lot in the light.

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      Nothing cheap, but I have seen the AC Hydraulic DK13HLQ which is pretty close to what you're asking for. The problem is the hydraulic cylinder mandates that the back of the jack be a certain height and Skylines have fairly deep inset floor jack points. A more certain and cheap option is to get some nominal 2x10 inch lumber boards and have one board be 1.5 feet, the other board 3 feet. Glue it all together with lots of clamps to maintain pressure. Make two of these. The ramp suggested above is a good idea, it takes quite a bit of clutch slip to get over each of the boards. I only need the first ~1.5 inches for my low profile jack on a standard ride height car but a lowered car you want to go up to the full ~3-3.5 inches. Paint it or store indoors if you want it to last.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok. And Nistune? I read (here too) mainly on Stagea threads that it can by "turn off" with Nistune. But they say they still had the sensor plug in. Next week iam going to the Nistune(and other ECUs) tuner so i can finally make it work. I drove the car home and apart from the cut it drove great. No misfire no smoke no hesitation or rough start...so hoping it is this sensor that is missing

      I just stack 2 pieces of 200x50 timber on top of each other. Total length about 900mm, with the top one being a little shorter and both having a 45° angle cut on them to make the front edge a bit of a ramp. Put these in front of each front wheel, drive up on them, throw the trolley jack under. Takes 1 minute. Scissor jacks can eat a bowl of dicks. I never use on under my car unless desperate.
