Cat NPP 20M. AL 04 Code

Hi there
I have a little cat pallet truck with the sauer danfoss ac controller. It comes up AL04 code and stops the traction from working. Also the battery indicator is displaying low.

Have changed the Battery indicator. Also have jumped the truck with another battery still the same problem.

I noticed that if i start the system and try run the truck immediately before the AL04 fault code comes up the truck drives a bit them stops with the Al04 code again.

Any wiring info and fault code info would be appreciated.
