All I know is, the bike is up and running again. Replaced the battery last night, and rode it to work this morning.
The battery never gave me a hint of warning that it is about to die on me. On Saturday, i rode the bike twice. Once to the car wash to have it properly cleaned, and later to the pub to watch our Springboks (national rugby team) play and beat France.
Like I said, Sunday morning was a different story. Turn the key, normal diagnostics check by the displays, etc, and as soon as I touched the start button, everything went dead, and stayed dead.
