Had battery checked replaced battery cable ends. hooked back up then there was no power to dash/ignition. All the fuses ok in cab next power box under hood the fuses there ok . so I replaced the wall mount solenoid and the pcm relay. Still Now power. Int.lights door chime and head lights work! but nothing in the dash.HELP! Where do I need to check from here???
