i bought my r33 gts about a month ago, the battery was stuffed, so i bought a new one. about 2 weeks later the new battery started playing up and seems to be draining itself if i dont start it for a day, ive checked everything that could be draining it but all i can find is the secruity light that flashes when the car is locked.

any ideas why the batterys draining.?

also when you got ur keys in hand,pop the ecu kick panel off and see if the ecu is on or off.

i had same problem with my battery going flat after not driving it 4 5 days,was because the ecu was hard wired to battery,

solution,put switch between bat and ecu,also good 4 random switch in-case sum1 trys to whip your RB

just wanted to give an update on my problem, i forgot to mention that the car hasnt been going anywhere as its unregestered, so i thought maybe this could be causing the problem.

also i took the battery out and charged it up over night put it back in, it worked fine for about three days now im getting the same problem..

im really assuming its just cause the the cars not going anywhere so the battery drains itself, but it could be somthing else

thanks for the help so far.

      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.

      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.
