2002 FLHTPI speedo began intermittent malfunction few days ago. Suspected loose connection somewhere, but had doubts because it would occur on smooth roads and not always occur on rough, bumpy roads. Only real clue was if I shook handlebar, backlight and odometer would flicker. Removed fairing and was able to track down bad connection. Distressing part is that it was in a bundle of wires with vinyl loom, no signs of kinks, cuts or breaks. Not a sharp bend, fairly straight. Cut out bad section and spliced. Had it been farther down it could have meant major tear down.
