Well i just went to put a new battery in my 06 1200custom because the old one melted a negative terminal post and it keeps blowing a 15A fuse that is attatched to the cable with the main 30A fuse. Has this happened to anyone else at all, some help would be great thanks?

 

I really don't think the battery is your problem. A battery is merely an electrical energy source, Something else is drawing the current an frying things, but it is not the battery

 

Your battery is most likely not the cause. There is probably a short somewhere on your bike that killed your last battery. You need to find what that is.

 

thanks it ended up being a short in my speedo, so I have to get a new one.
