I need help to find out what to check next. I have a 97' FLHRI and am getting 7.15+ volts at the cam position sensor (should be 5.0), I have already melted one cam postion sensor and burnt out a EFI tuner (cheap BK model on closeout). bought bike 5 years ago, soon after noticed that the cam position sensor was melted and i replaced it. 4 years ago installed aftermarket V-Twinn tach-speedo, Bikers Choice EFI tuner, exhaust, air cleaner. 3 years ago burnt out the tuner and replaced with a Power Commander II and started looking for electrical problems. 2 years ago took bike apart and repainted and checked all wiring harnesses. Noticed that tach seemed to be reading odd rpm, 3,200rpm @ 70mph (thought it used to be 2,800 @ 70mph). only electrical addon is led tail lights. I am disabled and have only put 1200 miles on bike in the past 5 years. I would ride a little more now, but i do not want to burn out another tuner or cam position sensor or possibly something else. Any help on what i should check would be appreciated.
