I own a 1997 Softail Custom (FXSTC) that won't say boo. i have absolutely no elelectrical. I have a brand new battery, clean terminals, good ground, checked all fuses, installed new relay. when i turn the ingnition on, nothing lights up. battery goes from 13v to 0v. It is like i have short, which doesn't make any sense since it has been in storage for the winter. Are there any electrical components which could have failed that would cause this?
