S-85 Boom Won't Retract

[bostonbob1958]

I am trying to figure why our boom won't retract from the basket every other function works fine. All functions work from the ground. When I switch the wire from the extract to the retract it works from the basket. I've got a 32/21 code, angle sensor fault. Where can I get a wiring schematic?
