Hey everyone. Im new to this forum and still somewhat green when it comes to working on compact machinery. I have a Bobcat S740 thats throwing the M7504 "Drive No Communication" code. There's no diagram sticker on the fuse box and I dont have a Service Manual, Operators Manual for this so I have no idea which fuse/relay the controllers are on so I can start figuring out whats wrong. Only thing Ive done so far is replace and rechecked all fuses and relays.

Would anyone be able to help me with a fuse box diagram, wiring schematic or some kind of diagnostic procedure?
I really appreciate any and all help!

the drive controller is located under the cab. after lifting the cab you should see a plate just to the rear of the opening where the seat was. the controller is mounted underneath the plate.
i cant recall if the drive controller has a separate fuse or not.
