Plenty of power to the cab, including lights, radio, etc. It will not crank. This is what I know:
Starter has been bench tested.
Battery has been bench tested.
Good cables and terminals
Battery is grounded to frame and engine
The starter will not crank when I jump it straight from battery with both key on and off.
All attempts have been done with brake on and off, emergency brake on and off.
There is no clicking in the solonoid but there is a clicking at the fuse/relay box by the battery - I can feel it but not sure which it is even after pulling each and turning the key.
The starter wire has been pulled and tested - no power is coming from it.
I believe the power is getting to the engine bay because of the clicking sound from the relay box by the battery.
