Voltage comes off the positive post of the starter solenoid. If you have no power to the dash, look around the starter for a fusible link. Usually it will be on a ground wire or cable. Looks like a fuse soldered into a wire, you will need to check it with voltmeter or test light for continuity.
Do you have a voltmeter you are testing with? Do you have battery voltage to the keyswitch, past the fuse panel? You have voltage past the 40 amp fuse?
