I have a 2001 FLSTCI with 60,000 some miles. The ECM fuse started blowing, I replaced it 4 times and then the coil burned up on the rear cyl. I went to Harley to test coil and ECM off bike and they said they can't test them off bike. Put on new coil and went 30 miles and once again the ECM fuse started blowing and then the new coil went. I told Harley I am not just a parts changer, I need to troubleshoot out the problem first. What can cause the coil on rear cyl to burn up twice. I have my electrical Harley troubleshooting book on the way. Any ideas Tom
