Hi, I'm new here but I've researched on this forum before.
Lately I've encountered this error code 57 on my Crown SP3020; the machine can lift up/down, but unable to move forward/reverse.

Some research on the topics here found me 2 threads, both which leads to finding faulty traction fuse.

However i've done the following checkings:
1. Traction fuse is ok. Took it out for continuity test which registers it at <1ohm.
2. Serviced the drive fwd/rvs contactors with new contact points
3. Checked the drive motor, no fault.
4. Cross-checked with a good working machine for the Steering, Brake and Power (the one with many wires) panel, all works.

I'm really stumped, I hope you guys can help me out.

Thanks
