It28f no powe to dash and no movement

[4digger]

Hello. We have a cat it28f loader. Loader was moving fine then all of a sudden the there was not power to the dash and no movement in the transmission. Now the loader starts fine but no power to the dash. I’m assuming the I lost power to the ecm. I’m hoping somebody can give me some hint as to where to look or what to check. Thanks in advance.

A serial number might get you a wiring diagram so you could at least have a road map to follow where the power starts and where it stops.

As it starts at least that would seem to indicate the disconnect switch and some of the wiring is functional.

Any update on this? I have the same exact scenario going on. No forward or reverse and no dash lights.

If you want an electrical schematic the first thing you have to provide is a Serial Number in order to identify the correct one.

When you get the schematic look for the main cab relay. It is responsible for cab supply power. It is energized by the key switch.
