Four things can cause this:
- a short to voltage on the Y/BE wire
- a bad ECM
- a bad coil
- a bad piggyback device
Since you replaced the coil and removed the PC you only have two other sources of the problem.
I am having the same problem on my 2006 Dyna Wide Glide. I replaced the coil but did not fix the problem.
1. What's the Y/BE wire?
2. Is there a way to test the ECM?
3. Is there a way to test the coil other than on the bike? (Maybe I swaped in another
