I've always just used the key to turn the bike on and off per the dealers instructions to me when I picked up the bike... never heard the sound you speak of.. the only thing I do when starting the bike is wait for the fuel pump to stop before hitting the start switch .. so far so good .. no problems

another difference is that I always leave the key in the bike in the garage with a battery tender hooked up.

No help but my bike does not make the noise you describe. I also use the kill switch as the dealer instructed except when I forget. The only noise it makes is when I turn it to run and it sounds like gas being pumped in.

Interesting that no one but me has heard the noise when shutting the bike off...

Maybe it's not normal!

I'm going to talk to the dealer today, and maybe i'll get some info.

DG Sporster.....You are not crazy!!! This is a REAL problem. I have a '07 XLC 1200. I bought it in Sept. of '07. I had less than 200 miles on her when My battery went dead. Called the stealer and they told me to come up and get a new battery. Installed new battery and went for a bout a 20 mile ride. Put her in the garage and went about my day. That night when I went into the garage, I heard what sounded like a kitten purring. It was coming from my sporty. After investigation it appeared to be coming from somewhere under the furl tank. No key in the ignition, and I always use the kill switch and then the key. I had to disconnect the battery to make it stop. This is what was killing my battery obviously. I took it up the the stealer the next day. It was in the shop for 3 days. They couldn't hear any noise and refused to do anything about it. I had to call Harey direct. I told harley that i wanted either the ignition changed or the relay block. With much regret the stealer did change out the relay block and the problem hasn't returned since. I have been trying to find someone else with this problem just to satisfy my curiousity and make me feel not so crazy. I am sure we are not the only 2 people that have experienced this.

Seems like I've heard a few folks say they've had "battery issues" with EFI sportys. This thread should be made sticky.

YES!!! Finally some confirmation....

What was wrong with your fuse block?

You said it!

Chris: Sorry if i offended you. If you are a competent tech, who truly knows that being a mechanic is NOT the same as knowing how to follow steps in a service manual, then i salute you. Unfortunately, your a rare breed. Would you care to move to NC?

DG Sportster....Not sure what was wrong with the relay...they removed mine and get this....put it on a Strret Bob to see if it happened on that bike. I never heard anything else from them about it. I was just pissed that they didn't believe me and were going to do nothing about it. They even went as far as to say " just put a battery tender on it every night". That was when I really blew my cork on them!!! The one thing that I can say is it has to be either the relay or the igniton. On mine the relay change seems to have fixed it. I was really wanting them to change the ignition first, since one would think the power would flow through the igniton first.

I have a bit of a theory...

These issues seem to be related to washing the bike ( i also found a post at HD forums about a Dyna doing the same thing after a wash ). Mine had been washed about 2 days prior, but i can't say for sure how long the IAC event had been going on before i caught it...and the relay tapping i did seems to have stopped it, it hasn't done this in 3 days now.

My fuse box had corrosion that looked like chalk, and literally had a oxidation path between two or three of the blades on the system relay. I assume this corrosion came from washing the bike, as the battery appears to look like new. Keep in mind that this is a month and a half old bike..... in my opinion the MoCo did a fairly crappy job of protecting the the panel from the elements.

Is it plausible that some stray current is finding it's way into the unswitched side of the harness through this corrosion, and that the cycling is actually the ECM attempting to energize the various circiuts, which immediately overloads the corrosion "path", causing the ECM to shut back down, and cycle the IAC to "park" ( as it's called in the service manual ), and then the whole thing repeats?

I had thought about not cleaning up the fusebox just to make this get fixed by the dealer. Then i remembered that the same fuse box would be installed, and would likely do it again in a few months. So i've decided to clean up the corrosion with electrical cleaner, and use dielectric grease on the relay tabs to stop it from returning. After that, all i can do is wait and see what happens.

I do have to wonder how much the service life of my IAC has been shortened by all this....

Updates when they come.
Thanks to all of you!
