Hi all - I have an '09 International CE300 bus. I've recently replaced the flooring front to rear and after hanging out in it for a few hours I realized I do not have a radio, the panels/switches for the AC no longer light up or come on and the panels themselves have no power. They have no ignition power when ignition is on BUT everything else seems to work fine. I can start the bus up no problem, all gauges work, lights work, etc. It seems to be a shared issue so I am going to pull every single fuse and check it out tomorrow but I wanted to write this post ahead of time in case I can manage to find wiring diagrams.

I think the easiest would be sourcing the reason the radio is not coming on (ignition switched on) to find out where it's coming from. Schematics for the transair AC boards show that it's a fused 10A power from battery but I do not trust it at all as I've had a lot of inconsistentencies.

what's there to trust? just find the fuse and check for power...

Schematics are almost never redrawn when modifications are made or options added later...like A/C units.... Schematics are a guide and in some instances, a bible....

You probably ran a screw thru a wire when you did the new floor.
 
Nope ran no screws into the floor. The most fun is having a fuse box with no fuse box diagram :) Yes I can of course run a tone on the ignition wire then spend hours to manually map it out myself but I thought maybe, hopefully, there was a wiring diagram to make things easier.

Wow I am just realizing that the wiring harnesses are numbered? I assume this is a circuit # and not the gauge size as for example the left knockout windows / emergency exit windows have pink with "14" and an "_" at the bottom to indicate the end of the number. I used that to check wiring diagrams for anything emergency/window related for pink and or 14 and found nothing but can you confirm whether I'm right or wrong?
