Hey guys i just got a new head unit installed into my car and since then my battery keeps going flat.... also when i turn on my lights my head unit sometimes restarts and the car loses alot of power.

what could be causing this i was told that it could be the alternater or that the head unit is not earthed properly.

the car is at about 14.25volts and can drop quit a bit

r34 GT-t

also wondering if any one knows if they came with stock splits and if so where they could be.

dose the head unit turn offf with the ignition or do you have to turn the unit on manually.

if you can pull the deck out and change the earth to some metal in the dash. some people will wire the earth up to an existing wire that looks like a black earth wire but turns out to be a control wire for your headlights.

to check your alternater start the car and turn everything on lights(high beam) stereo, then check your

volts from the alternator it should still be up around the 14v. check your battery as well that should stay firmly around 14v if the battery loses power the alterantors not doing its job and will probly need new bushes(about 12 bucks) or new module.

when you say the car loses alot of power, do mean engine power or volts. cuase if its engine power

it most probably because of the lack volts not being enough to supply a desent spark. so if its running of the battery it aint going to last long.

    • 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.
