The dreaded click indicates a drained battery. There are a number of things you can do, by way of finding out why. Remove the battery from the bike and get it tested at a local auto store. That should identify if it has developed a fault (such as a failed cell), but if it tests OK then charge it fully over night before refitting it.

You may have a charging problem, so test your system. There are helpful stickys in the DIY Electrical section of HDF. Finally check for loose or corroded connections in the main power and charging circuits. The most inaccessible terminal of the main power cables is where to start!

 

And...if you end up needing a new/replacement battery - go to http://www.batterymart.com/?search=1...OoQatyMLRxqQ.1 and order...just used them and it was 3-days from order to receipt @ my doorstep & 1/2 price of OEM HD...SWEET!

 

The Battery Tender Plus shown above has kept my battery alive and well since 2007.

 

Thanks guys. This is all a lot of helpful information!
