While riding my 2012 Heritage Softail I got a red warning on the tach screen. It said Bus something. Everything quit, turnsignals, horn, starter, everything, checked all 3 fused, no problem, battery good and connections are too. The only thing that comes on when I turn switch on is low beam. Any ideas?

Was it a can bus communication error ?

If so you may need to check your wiring harness for shorts or opens.
