Put a new battery in last weekend, today it's dead. Worked fine till today. What's the best way to find out what is draining it. The battery I took out did not look old and I now suspect is okay, but the guy I bought the bike from said the battery was bad. I did hear the fan run a few min, after I cut it off yesterday.. didn't think it ran long enough to drain the battery.

mjonesjr8, If you have a multimeter, remove the neg cable from the battery. Place the meter on it's highest amprege setting, pos lead to cable and neg lead to the battery. You should read zero or something in the thousandths. If higher, remove one fuse at a time until the reading is zero.

after I get to zero, what then?..

I was also reading the very good thread about replacing the rectifier with a better one..

One more stupid question where is the fuse box on these bikes?

mjonesjr8, Once you read zero, you'll know which circuit is drawing from the battery. The fuse box is under the rider's saddle. Mine's in a gray colored plastic box.
