I just changed the handlebars on my 06 heritage. I noticed when I took it for a ride I have no Speedo/odometer, no lights in dash except security key light and neutral indicator, blinkers don't work nothing. Ive checked and rechecked the plugs.all seem good any ideas as to why this is happening?

 

My 2000 FLSTC had the same issues. Final fix was replacing a bad voltage regulator. Been 6 months no issues. BTW I initially changed the speed sensor that lives in the tranny which had no effect.
