1 The Silk Road was established during the Han Dynasty. 2  This trade route from China to Europe was a great source of wealth and luxury items. 3  Buddhism first came to China during this time. 4  Social status was very rigid.
Third, the outer shield affects common mode impedance of the cable outside much more than it actually affects common mode ingress. When the braid was removed, excitation power had to be significantly increased to maintain the same common mode current. This shows a higher common mode impedance of the shield.
Dirty gunky grease on your cable is the cause. At lower speeds the cable binds slightly and then jumps when the binding is overcome. This causes the spedo needle to jump. I believe that the cable comes out from the spedo end. Pull out, clean off the old grease, use new graphite type spedo cable grease on the cable and reinsert. You may have to take the end loose at the transmission to reinsert the cable into the drive. Good luck,
