THE UNBELIEVABLE HAS HAPPENED! My Spyder STARTED with no issues at all! After replacing the two large relays yesterday, I tried starting it, and got nothing. This afternoon, I went out to do try some small relay swapping for fault isolation, but figured I'd try to start the bike before beginning. The self-check ran, and it started immediately. I shut it down, pulled the key, and then put the key back in and started it again. It started immediately again. I am, as the Brits say, gobsmacked! I took it for a 5 mile drive, came home and shut it down. The I put the key in, it went through its normal self-check routine, then started right up. I'm still considering swapping out all the colored fuses for new ones, and I'll take a look into replacing the small black relays. But right now, I'm in shock. LOL

My sincere thanks to all who helped me with this problem. You folks are the best.
