Strange electrical problem!

On my girlfriends 2001 sportster, she bought the bike with chrome switchs instead of the factory black ones. They have a little different of a design. But anyway i changed out her throttle tube the other day then the bike started stinking really bad of burnt plastic. We instantly turned off the bike and started looking for the problem. I noticed the Throttle cables were very warm. I opened up the side panel by the battery and it has melted part of the fuse block. What would cause this? all i can think is a hot got touched by a ground and then caught on fire. I thought a fuse would have stopped this from happening thou. Maybe the guy before us had the wrong size fuse in it? any help to figure this out would be great.

I bet you pinched a wire in the throttle. My dad did the same thing on his bike.

yeah im going to look at it tomorrow and make sure its all good in the handlebar controls. I HATE aftermarket chrome controls, well controls period!
