Default Roadking draining battery
I have a 2004 Roadking that will drain the battery if it sits very long without starting it. Any ideas what to start looking at? The battery tests good and takes a charge.

Not really unusual for that to happen after sitting for a very long time. What do you consider "very long"? I plug in the tender any time the bike sits over a week without being started.

Usually a couple weeks and it's down enough where it won't start. I've got a battery tender I can hook up. This is a fairly new bike to me and hadn't had that issue with some others. Thanks for the info.

No radio. It does have the keyless start. I guess that has to stay on looking for the key.

Does it have a security system?

Connect a known good digital meter to the battery, look for voltage drop. If drop is present, pull fuses one at a time until you see what the culprit is.
Tip: If you pull the maxi fuse and volt drop starts, suspect battery, battery cables, or main wiring harness. With all connections removed and volts drop, bingo, it's the battery.

Just because a battery "tests good" doesn't mean it's really OK. Disconnect it. Charge it up and see if it still loses it's power after a week or so.

i think you're confused. if you don't have security, then the bike is not 'looking for' anything. the key is for locking your saddlebags (if not leather), tourpack (not on a roadking), and ignition switch.
