Check all the grounds body to motor battery to motor ect.You should get some thing to work .

 

the one that comes out of the negative to the inside of the fender?

 

thats one place to start. then check the ground straps that go from the engine block to the frame. then check the negative battery cable. check any black wire that is bolted to the frame somewhere.

 

I would check all the fuses 1 by 1, then have a look at the fusible links
located right on the starter wires and put a meter down there or a 12V test
light turn on the key see if you got any juice down there to the starter..
also do a no start( search) here on this site...
