Headunit Restarts Itself

Hey guys,

It only started happening today, when I'm at the lights and I ride the clutch a little, sometimes my headunit just restarts itself and continues playing. Is it something that is battery related?

Another thing that I noticed is, when I was driving home tonight, when I stopped at the lights indicating to turn, all my interior lights just blinks at the same time as my indicators, and I think my headlight as well (slightly).

Appreciate it if anyone can help me out :P

check your alternator.

How do I do that? (sorry if it's a dumb question :))

Also, every morning or whenever I haven't driven for a few hours, I start the car, it takes less than 1 sec to start up. But if I do a short trip to the shops and start the car again within 10mins or so, it will take a few secs to start it.

Is that because of the alternator?

Thanks Chris!!

yep sounds like a bad/problem charging system , but could be a bad battery(low current holding or low water if its a wet system) or bad ground/positive terminals loose corroded ?

some auto shops have free testing on batteries/alternators,

buy a cheap digital volt meter for like 10 bucks to check if your car is charging or not ? jaycar, supercheap or ?

needs to be around 12v with engine off

roughly 13.8-14.4v when running

if all good turn on your lights, with engine on and retest voltage, is it getting lower and lower or stable ?

post up the results

and clean and tighten the terminals (post cleaners/wire brush ) is only a couple bucks

if you have a small jap battery , expect it to be dead ...lol , good reason to update your battery and terminals to Aussie standards

most of the time it's a bad terminal, R31 did that and the positive terminal was cracked on the underside, causing resets and low voltage

      Neil's R33 Gts-t Build

      Then today, I went to visit a man with an r33 hat Peter and Road and Race sorted the alignment. As it is being set up for general track/hillclimbs etc it has a heap of caster (7o), less camber than I am used to (1o front and 2o rear, as the caster looks after that in turns without the braking downsides), 3mm front toe out and 0 toe rear. Will see how that goes and track tyre wear to see if it does need more camber, but adjsustment is also limited with nismo arms and adjustable bushes at only 1 end. It does have a bent inner tie rod on the driver's side front but as it came up within spec I'll just leave that as is. So, that is getting close to my chapter of this story....could of tidy ups then a shakedown in early October before it finds a new home.

      So, it went to Unigroup for a run in and tune on Friday, everything went (generally) well. In terms of fixes, the engine was good and there were no leaks. It needed plugs (I hadn't checked them because the coil pack cover was on a new engine and I couldn't imagine they weren't new.....but turns out the temporary plugs to just keep it sealed up were in there.....new plugs gapped to 0.8 and it was fine from there. Also, there was a little preload on the clutch slave which caused some slip. I haven't had the box off so I don't know what the clutch looks like; my guess it is brand new and the pedal had not been adjusted....backed that off a bit and it held fine. Last thing will have Dose crying....the idle especially when cold is a bit difficult between the cams, forward plenum, atmo blow off valve and an 80s air management system. It is fine when hot but a little uneven when cold, will see if I can sort or at least improve that one cold morning. Other than that, tuning went fine. It made 245 but was pulled back to 227 which 2 opportunities to improve in future. 1. The factory CAS is not great and was jumping around at high RPM, so Mark took 2 degrees out up top (that is why it stops making power and lost 20kw). Very safe this way and the extra power is available but will require a more modern ECU and better cam (or even better crank) sensor 2. The 2871 in factory housings is very big for a low mount, and the internal wastegate is too small, so it was creeping from mid range all the way to redline....the duty cycle on the boost controller is turned down a little for safety. That is much harder to fix, it would need a large external gate and that would require a whole bunch of other changes, so it will go as it is for now. It feels nice and healthy and safe, so should be good for about a billion laps like this.

      Slight brake pedal stutter after new pads

      what sort of caliper are they? If they are a slider and you gave everything a good clean, you might need to regrease the pins. My guess though is they will come good after some abuse as suggested above
