  • engine wine know how its there but can't get rid of

    Hi all,
    First of all I have searched the forums tried every possible solution I have found on this forum with no luck so here I go.

    I have a very common engine wine noise problem.

    first of all power wires & rca cables are separated
    all computer cables are separated from power and speaker & rca cables
    using a head unit aux in (pioneer DEH-P960MP head unit) for computer
    external SoundBlaster soundcard
    shuttle pc
    1 4ch amp
    1 mono amp
    300 watt inverter


    If I do not ground any part of the computer I.E. The case,power supply, motherboard etc I get a loud "buzzing" interference noise. At that point I do not hear any "engine wine" noise that is consistent with the rpm's of the engine. if I ground the case,motherboard,power supply or even all of them the "buzzing" noise goes away but then comes the "engine wine" noise.
    (tried single & multiple grounds to different points on the computer parts and different grounding points in the car.
    with sizes from 14g to 4 ga wire but does not help)
    also tried ground loop isolator by the soundcard and even going to the amps with no luck.

    I am not sure how to get rid of the engine wine noise.
    I know where its coming from because when I ground the case its starts then, but I do not know how to get rid of the wine.
    any ideas
    Thanks

    you try grounding the HU and computer to the same point?

        does this just happen with the PC, or is this an issue with the amp? I know a friend who's amp does this....and i believe its an internal issue

          Hi,
          Thanks for the response
          If I have the computer off and just play a cd in the head unit there is no" wine"
          Also if I unplug the computer from the inverter there is no "wine"
          If I have the inverter running with the computer not pluged into there is no "wine" from the inverter.
          It only comes from the computer when I ground it to get rid of the "buzzing" noise.
          Any other ideas
          Thanks

            two things, did you ground the inverter?
            secondly, make sure nothing is shorted on your motherboard, make sure you arent using any of foam or anything to cussion the motherboard or anything

              what are you talking about, the 12v side of the inverter HAS to be grounded ot work

              and if you're taking the 120v side he said he grounded the case whoich is cnnected to the PSU which is connected to the 120v side of the inverter.

              have you tried running direct fromt he computer to amps?

                Hi,the inverter is not grounded besides the (-) terminal on the inverter because the case of the inverter is plastic.I am not sure if i open it up where to ground it to.
                also would that make a difference?
                because like I said I can have the Inverter running by its self and there is no " wine"
                The motherboars is screwed down to the metal case with out any cussion.
                Thanks

                  i'm talking about the case of the inverter, the case might have a different ground. But also if the inverter and the amps dont have a common ground that could be an issue as well

                        Also I forgot to add that I tried not using the inverter just plugged the computer into the house power and the "wine" is still there.

                          Hi, yes the inverter is a plastic case (the only one i could find that would survive crank)
                          The pc is a metal case.
                          Thanks

                            With all those components running, no matter what you do, your going to get different grounding resistances.

                            Best thing to do is ground as much as them as you can to one grounding block. For example, under my rear seat, I have a grounding block that takes like 4 inputs and goes to one 4 gauge wire to a big bolt that connects to my frame. I ground my PC PS to that, the Amps, and my Cap to that.

                            Also running a USB soundcard will help get rid of any noise that is created before the soundcard on the PC side.

                            Goodluck, sometimes it takes alot to get it to stop, but it's possible.

                              its the inverter, ditch it and get an OPUS, problem solved.
