E 450 no power when key inserted
I own a 2007 E 450 super duty 6.8 v 10 It was working fine but I had to jump start to charge the batteries and then I replaced with new batteries and it has no lights / power on dashboard nor any engine sounds.
I have a mechanic friend and he traced the wires, alternator and starter are fine.
fuses also look good.
he thinks it could be the computer we jumpstarted it ( incorrectly) or so mice chewed any cables.
any suggestions to diagnose my issue is greatly appreciated.
