pt 40 wont start

[real11estate]

Thanks for all the help to answere a few questions it will not turn
over with the key ignition front or back. The starter will turn if
shorted by hand (dont try this at home LOL). I followed the wiring for
Atec from the tranny all the way to the front compartment where the
air service brake valve is located and a ton of wires. When I
unscrewed all the fasteners and opened the front of the bus I was
greeted with a whole lot of rodent trash in nice bright colors (wire
insulation) soooo..... I think I found my problem the Atec harness is
no longer. Thanks all now to rebuild and see if the electronics held
up to it when I tried to start the bus.
THANKS ALL
Matt
