Try to make this short,my 93 heritage softail classic won't start,no power so I was told main circuit breaker,so I buy new one put in and I got power,then I hit ignition switch and everything dead.I go to different shop buy another breaker and now I still got no power,at least when I changed last breaker I got power,did I blow something else,I also installed a new ignition key switch.my bike doesn't have fuses only breakers,can anyone help me out so I can save some money,getting broke,expensive owning a Harley.
