Eton 50 blowing fuse
 

I have a 05 Eton 50 that will blow a fuse as soon as I turn the key.
I've taken all plastics off and unplugged everything. Looked for any damaged wires or grounds. Only thing now plugged in is a brand new ignition switch. Doesn't matter what size fuse it is, as soon as I turn key it blows instantly. Any help at all would be great. About to loose my mind because nothing is plugged in to find the problem. Thank you
