Is your alternator alright? It should be sending roughly 14.4volts to your battery and electrical system to run everything. Also, there's usually a regulator on the alternator which kinda controls how much charge is going out from the alternator so as not to over-juice your car's electrical system. That could also be causing problems.

The third thing, there's another fuse box inside the car - pull out your coin tray on the RHS of the steering column, and there's a fuse box hidden behind that with a bunch of standard blade-style fuses there. i can't remember if there's any there which may sort out your problems, but it might be worth a check...

Have had the exact same problem before. I cleaned the inside of the battery terminals with sandpaper to remove the hard crust that forms from the oxidisation at the terminal. That fixed it for a while, but then the problem resurfaced. I then pulled the other plug that sits on the positive terminal and gave everything a good go with the sandpaper. Hey presto, no more problems. I used to work at a battery fitting specialist earlier in life, and you would not believe how many people came in to us after spending hundreds on new alternators, electrical components etc. You could see that the battery would be in clean enough condition, but the hard surface that forms after a couple of years can stop the energy flow from the battery. Of course, when you checked it with a battery tester it would come up fine.

I'm not saying that there might not actually be something else wrong, but start the search for the problem at the source & you could potentially save a bit of cash..... and thats gotta be a good thing!

Heres a helpful hint that I got from an auto sparky - if you have that green fuzzy looking gunge on the terminals, the very best way to get rid of it is boiling water. Just boil the kettle and splash some on before you take the terminals off and it will disappear like magic. :mellow:

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
