When I tried to start the bike today, I got nothing. The lights came on, but nothing else. When I was finally able to decipher the trouble code, it indicated that the problem was with the turn signal control module---part no. 68921-07. As the bike has no TSSM feature, I'm wondering why this would keep the bike from starting. Oh, the turn signals don't work.
Any insights are appreciated.
Obviously, there are no absolutes.... but any time I have an electrical gremlin... I start with checking the battery.. not just voltage, but load test.
If that's OK, I then check battery connections, to include the main ground to frame connection... I've had electrical "issues" over the years that were nothing more than a bad battery and two that were the main ground to frame connection came loose... it's amazing the weird things that can happen when you don't have good, solid power... On a newer EFI bike, you can get a bunch of seemingly unrelated trouble codes just due to intermittent power..
Once I confirm I have good, solid power... then I check the codes, and go from there...
Good luck with your diagnosis... keep us posted...

Thanks, Hat,et al.
Here's what the problem was. I've only had this particular bike a short while, so I'm not real familiar with its idiosyncrasies. Because of the weird turn signal code, I removed the right side switch housing, and I saw that a prior owner had cut the wires to the turn signal switches and spliced them back together. A small bit of wire was protruding from the splice. As near as I can tell, that wire came into contact with something and blew the ignition fuse. That would explain the code and the no start condition.
Everything seems to work now. Thanks again.
