916a1 no power in the cab

[TadB]

Recently bought a 916a1 to use as a lowboy truxk with my company. Had the guy that cleans all my equipment wash it this past weekend. Didn't clean inside the cab or under the hood. I went to move it in the shop today to out on the new fifth wheel, no dice. I have power at the batteries, starter ect. No sign of power inside the cab. Not gauges, buzzer or lights. No power to the back of the ignition switch. I'm assuming it's going to be something simple he hit with the pressure washer....any thoughts? Thanks In Advance!

Look for a broken off wire in the battery box area.

Also there are two single 25A fuse holders next to the frame, above the battery box that protect the ECM, will turn over but won't fire if these are dead.
