I found my battery dead on my 2009 Dyna even though on a tender. When I charged it I heard my efi going even though ignition switch was off. About 30,000 miles.

Is this common?? Any idea what this will cost to repair??

Thanks all

 

You need a new Ignition switch. There was a recall on them a while back and I'm not sure if you're too late to have it changed out on the companies dime or not. Better call or visit a dealer in your area to check.
