Ok, I know this is a dumb question, BUT, I'm kinda new to Harley Davidson Motorcycles. I just bought a 2001 Softail and when I turn the switch on an indicator light that looks like a "KEY" comes on until I crank the engine. What is this for?? I did'nt get an owners manual and I can't find the answer to this question in the Clymer Manual that I have. Somebody help this dummy please.. Thanks.
