You're right, the sound came back even after using white lithium, but somehow disappeared a few days ago and has yet to return.
I can't believe that the cable is as nice looking and clean as it is but is still considered "bad", but what do I know.
I don't care anyways. I don't even use the speedometer. I just matched my speed to my Tachometer and now use that to see how fast I'm going. When and if my speedometer ever finally breaks, I highly doubt I'll actually fix it. The tach is much more reliable.
Thank you very much for your help.
