This past month if I go two or three days without riding my battery will be dead. I replaced the battery thinking this was the cause but still had the same issue. I took my 06 FLHTCUI to a dealer today and they discovered that the radio, for what ever reason, is drawing amps while the bike ignition is off. Verdict is still out if the stereo can be repaired or will have to be replaced. Glad I have the extended warranty. Has anyone else heard of a problem like this?

 

The radio shoul dbe drawing power at all times. What is the radio pulling? You have the preset buttons and the clock that will pull power from the battery for the memory.

 

If I understood them correctly it is pulling 300 mAMP's.
