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.

      FD RX7 I would probably marry if legal R32 GTR is toughest NSX looks like it's made from leftover Prelude and Accord bits

      R34 Wheel Alignment Specs

      When going to a suspension shop should I send them the default nissan settings or just let them do their own thing? I ask this because I have aftermarket rear camber arms (front end is basically stock after I change to those nismo bushes)

      Ok sounds good, thanks for your help. Hopefully if I end up changing it to the nismo bushes I don't get that veering issue. I don't think there's a point in lubing up these bushes again. Weird that it it makes just as much noise with all the grease inside it versus without grease prior to removal. Bizarre.

      Yeah, you don't need camber bushes on stock arms to make a car drive straight unless it's got another problem. F'rigsample, slide the thing into a kerb, bend the front subframe mounts a little....subframe is now twisted, shifted or otherwise in the wrong spot...and you need to do funky stuff with the wheel alignment to get it to drive straight. Maybe a little more caster on one side, or a little more camber. FWIW, I can have my camber off side to side by a half a degree or more, and either way, so more one side, or more on the other, and the car doesn't really want to pull to one side. It will definitely ride road camber differently, and want to track uphill (ie, towards the centreline when on the LHS of a normal crowned piece of road, like it should) or want to roll downhill (which it really shouldn't). But on fairly flat road surfaces, like the middle of a 3 or 4 lane motorway, a half a degree either way doesn't make a lot of difference. I sometimes do quite a few miles with my wheel alignment messed up, because I don't always get a chance to set it right again after a serious dismantling, before I have to drive it to work again. Like, a whole week's worth of daily shuffle.

      To clarify, I meant nismo bushes, not control arms (don't even think that's a thing for my car). So the suspension specialist said, if I buy those nismo bushes which are perfectly centered it will cause my car to veer in one direction. Whereas he said the current offset bushes that I have were put in on purpose to fix that issue. This will be my third wheel alignment if I put these bushes in lol. My chassis is straight, all my rails are clean.
