have a hustler raptor that the owner had the ignition switch went bad, owner replaced but unit would not start. i found bad fuse, replaced tried to start blew fuse. have done a check of conductivity of wires found nothing, i know that i have ground just trying to find a real pain, i have disconnected clutch, voltage regulator still blows fuse. replaced solenoid no help. have not found any broken or frayed wires that would cause the ground. could the relays be bad thus causing the fuse problem, any advice would be very helpful thanks AC
