Hello folks, I’m helping a friend with his 5010HST. We’re not getting any power to the AC controls, or to the work light/ wiper switch panel on the right side of the cab. All the fuses check good, we have power on two different wires going into the relay box under the roof and no power coming out. The relay box has been replaced, that didn’t change anything. Feels like I’m missing a signal or a ground somewhere.
We have a wiring diagram, but it’s really blurry and almost impossible to read. Any suggestions on where to find one online would be appreciated.
