And he's off... well, maybe not.
I left this morning and decided to stop at Walmart to pick up a couple of items. When I came out, I couldn't start the bike. I put in a new battery, and the bike started.
There seems to be more load than the battery... not sure. The last work I did on the bike was to add an LED tail-light and a strobe module, so perhaps there is a short there somewhere.
At least it happened a few blocks from home instead of 200+ miles away.
