Alright, just thought I had completed my Rb25 conversion. The car starts, runs and drives, but I have a couple issues.

1. Wiring. Thought I had completed the wiring using the MANY sources going round. However I have no accessories. No radio, parkers (have head lights), no tacho (have speedo), no dash lights etc. The only doubt I had about my wiring was not using the green eccs relay from the 32 loom. Did I need to? Antone know what the problem could be? Note, there was a large spark when connecting the battery, however there are no blown fuses.

2. Noises. The main one of concern is a screeching/whining coming from somewhere. Sounds like near the gearbox, possibly the starter motor. It was really bad when i first started it and became worse with the clutch in. I used my old rb20 box, clutch, flywheel and starter during the conversion. When I was swapping the flywheel and clutch across I was worried about being able to align it properly, however I did my best and was able to align it with the gearbox in the end, not sure if this is relevant at all.

I'm so tempted to give up on cars all together at the moment, the only thing keeping me going is the fact that when I was driving it the noises stopped and it pulled hard. Oh, and my wipers work :) lol. Please help me get this thing working!

Thanks,

Josh

btw, using a series 2 motor and loom and I didn't use either relay, not just eccs.

Another thing I though of; The thick white/purple wire from the plug near the air box I left unconnected since series 2's don't have a separate Power to IGN Coil relay, should it have been connected to something else instead?

Josh, I am certain you have blown your main 75A fuse. Look at it CLOSELY as it is often not easy to tell. My guess is when you put the battery feed onto the alternator you you have earthed it against the alternator. There should be a plastic cup which prevents the feed from the alternator earthing against itself. This sometimes comes off so double check. I am talking from experience!

The other noise you were referring to is hard to tell from what you have described but was the RB25 an auto and if so did you remove the auto spigot and replace with a manual spigot bearing?

Cheers

OMG thank you! I don't know what I was thinking when I wired up the alternator, I had the cables in the wrong spot lol. Had been a long day. Everything works now! The noises have died down a bit now, I think I can suss out where there from.

p.s. Ben you are a legend!!!

      It is an absolute lottery. They can and have died at stock boost with low usage at all. The turbos are now anywhere up to 36 years old!

      Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months

      That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By GTSBoy · Posted

      Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
