Does it still have power if you pull the pink and brown wires from the solenoid? Remember the pink wire in front the brown wire in back when hooking it up (its just like underwear). If you have power with the two wire pulled off the solenoid you have a problem in the harness. start at the alternator and work your way to the firewall looking for burns or pinches. If you don't have power when the wire is pulled i'd try a new solenoid.
