I'm doing a Sand Patch Grade timetable run, and although i figured out how to turn on and use the dynamic brakes in the loco (putting selector switch to B and dynamic brake fuse to closed), but now I can't switch it BACK! Even with fuse open and selector on 2, when I use the throttle its still in its orange dynamic brake mode. I'm currently only able to pick up speed when coasting in neutral downhill but I can't apply any forward power. Help!
I'm not sure what happened, but fuse should be always closed. Maybe that broke something. Also are you sure, that you set throttle to 0 before trying setting selector to 2? That would lock it, rendering driver unable to use 1-4 positions
