Hey guys

i decided to go for a drive in my 32 last night, i hadn't driven it for a week and it has developed some strange issues; the HIDs were flickering on and off, and the power steering was cutting out and there was a high pitch buzz coming through the speakers.

the only thing i have done to the car recently was put new coil packs in and re gapped the spark plugs, but that was 3 weeks ago and it was running fine until now...

I know its hard with electrical fault but i was just wondering if any of you have come across this before or you have any suggestions for me?

Yea unless there is one under the valley cover i forgot about the only earth i would have touched would be the one on the ignition pack, which seems fine... but i just went and double checked it and the car has lost all power now, the battery is still nice and tight and reasonabley new, so i guess ill have to pull the multi meter out tomorrow.

So yesterday i tested the battery and found that when its disconnected it has approx 12.04v then when i hook it up it drops right down to 2.01v... i tried disconnecting the HIDs, audio system and coil packs one at a time with no change in voltage (they are the only aftermarket electrics in the car) so my thoughts are there may be a short somewhere?

I put a new battery in about 3 month ago.. but this one may be rooted because i know my amp was killing the battery (i took that out a few weeks back) i just thought if the battery was gone it would have had more trouble starting when i first noticed the issues with the headlights and power steering... And there seem to be something drawing way to much current anyway coz it drops 10v when i hook it up... but ill see if i can borrow a healthy battery from one of my mates and see what happens

Yea i tried that and had no notable change.. I went and got a battery print out this afternoon and it said "charge system failure" so looks like an alternator.. im told that they can collapse and the internals can touch together which could be causing the drop in voltage..

So i fully charged the battery and started up the car with a multi meter hooked up to the battery; started out at about 12.8 volts and dropped down to 12.2 as the car reached operating temperature.. when i reved the engine the reading went up to 13.2, so the alternator seems to be charging the battery. i turned on the headlights ac and radio and the volts dropped to 11.65.. i took the car for a drive and re tested the battery and nothing changed.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
