First up, not sure if this belongs in this section, so bare with me.

i got a 95 R33 manual turbo rah rah rah,

bone stock engine wise and body, just has some coilovers and swaybars, braces etc.

Im having issues with the Battery going flat after 2 days of no use.

Ive replaced the battery, battery leads and terminals,

disconnected the stereo, disconnected the key hole light around ignition as it would stay on when door closed and locked.

boot light disconnect as ive read they can go faulty. removed the turbo timer as the screen shit itself and stopped working (was working great intill electrical gremlins came in)

i had to removed a lot of unused wiring from a car pc install, was wires taped into the cluster, and fuse box, random shit here and there.

from what i gather now its all bone stock wiring wise minus the alarm and boost gauge.

just seems everything electrical is playing up, is it normal for all the dash lights, and clock and stereo to Dim when light puts on?

I havnt tested the alternator to see if its charging, but i put a brand new fresh charged battery in and it was flat in 2 days.

Any idea's on what to check, how to do it would be great, worse case is ill drop it off at a auto electrician, but would rather try fix it myself if possible.

Thanks

test your alternator my man. can do nothing until this is done.

Still doesnt explain why i freshly charged brand new battery went flat after 2 days of no driving. i literally put it in, turned key, it fired up. i shut it down and left it.

2 days later, wouldnt crank, just couple starter clicks. stereo worked for a second or 2 and then wouldnt turn back on. connect jump pack and it fires up like its a fresh battery,

i had the same problem years ago, it turned out to be a faulty relay staying energised even when key was out of the ignition = flat battery, id be checking this or any thing else related (as well testing alternator while your at it)

Have read something to do with the ECU relays, ECU stays grounded or something and thinks its still on. so flattens battery.

I have bought a Multi meter, so will check battery and Alternator ASAP.

Battery tests at 12.65V fully charged

When engine running its 14.22V,

Drops to 9.57V on crank then bumps up to 14.22.

With lights on, AC on, stereo on, and anything else i can put on, and sitting at 2000rpm its 14.17V

after car is off, battery reads 12.57v

test for battery drain it was fluctuating at 0.05 to 0.07 and every 10 seconds or so it would bash up to 7.00, this is testing on a 20amp setting on multimeter with the multimeter between earth cable and earth terminal on battery.

Disconnected the 4 fuses for the Alarm, it sat at a steady 0.03,

Removing the what i believe is the power window fuse from under bonnet it drops to 0.01-0.02

Removing the fuse labeled "electrics" going buy a engine translated picture it drops to 0.00 which im assuming is no battery drain what so ever.

If anyone can shed some light on this, then great stuff

yeah thats what causes most of the drain Mate, 2 posts up i said i removed the 4 fuses for the alarm, guess i should have put its a immobiliser as well haha.

My other R33 reads 0.03 drain and it never goes flat, even after no start in 2 weeks. so in theory the 0.01 from this 33 should mean it shouldnt go flat.... "shouldnt"

Odd thing is i had removed the fuses to alarm/imm over the weekend and it was still flat.. hmm.

Sorry mate, didn't see that post re: the immobiliser. I never really got a "fix" for the immobiliser problem (just assumed it was a power hungry immobiliser) so I just had it on a smart-charger for most of the time (rarely drove the car in the end prior to selling. Maybe a couple of times a month?).

STILL CANT BELIEVE YOU SOLD IT........

trace all wires back from the alarm mate. disconnect and tag them so you know what goes where. leave it as usual and see if battery discharges. only way to do it really.

also id check the size of your battery. i have some funky jap spec pager alarm on mine and have never had this issue....

yeah alarm is all disconnected and has no power to it, im hoping anyway.

Battery is new, 330cca, unsure of the other numbers though, bigger then the previous battery i know that much.

Im guessing the alarm spikes every few minutes when connected and slowly drains battery, as starter just clicks after 2 days

Yeah, I know. Miss that car heaps :( apparently the new owner blew the head gasket, which is unfortunate. Hoepfully it gives him the chance to build it bigger and stronger.

Bit of a band-aid solution but maybe jsut keep her hooked up to a trickle charger until you can get the alarm/immobiliser checked out. The chargers are about $70 or so from Ricebarn so def. a good investment in my eyes :cheers:

Replaced the alarm module with a new one, same brand so plug and play.

seemed good for a week. Battery was flat again this morning.

Getting a 0.02 that flutters to 0.03 and 0.04 reading on multimeter for the battery draw.

Should that number be solid? and not flutter?

Im about ready to drop it off at a auto electrician, its near doing my head in.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
