The speedometer doesn't work on my 96' 1200 Sportster but the electronic odometer read out and the back light still work fine. First thing I did was take out the Mag Pick-Up from the case and clean it of the metal shavings that were on it. Ran it and still no dice. I need to get the voltage and resistance numbers so I can troubleshoot with a multimeter. I don't want to just start throwing parts at it until it works so any help would be greatly appreciated. Thank you.
