Hey folks,

I'm suffering from a terribly annoying noise coming from the alternator. It's been there ever since I bought the skyline. I believe that this can happen when you have your input wires too close to power cables. So, I went and bought one of those noise cancelling things from jaycar and I was told to put this between the alternator and the battery, closest to the battery side.

I'm driving a series I R33 ('93) and the battery is in the boot. The only wire connected to the +ve side of the battery comes from the box next to it.

My question is this: Where should I be putting this device in?

At the moment I have it wired between battery and fuses, going into the amps, but it doesn't really do anything. I tried putting it in between the battery and this little box thing next to it, but the car didn't even start, so that quickly changed....

(In case I've confused anyone with what "noise cancelling device" I'm talking about, it's a cylindrical shaped thing with a positive cable coming out each end and a negative wire coming out one side. I'm told that that it doesn't matter with direction it's facing when wired, as long as it is grounded.)

If anyone can help me out with this it would be greatly appreciated - even though I can't hear the whinning with loud music, when it's down low it drives me up the wall!

Thanks in advance!

The noise I get is in every gear. I hadn't really thought of putting it under the bonnet. I think I remembered the guy in jaycar saying to go as close to the battery as possible. If I had the choice I'd rather install it in the boot rather than in the engine bay. If need be I guess I could put it up front.

Anyone got any further ideas or info?

Thought i would ask in here instead of starting another new post..... already asked the question ova in forced induction but havent got an answer as yet though i might have put it in the wrong place...

anyway here is a link to my question

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
