It's either a bad controller, two bad wires between the f&r switch and the controller, or a bad F&R switch entirely. I doubt it's a bad F&R switch, because it would have to fail in both forward AND reverse in order to give you these symptoms. This is considering you're getting power to the orange wire on the center pin, which you said was good. I would start by checking for power at the blue wire and the brown wire at the controller 16 pin connector. The blue wire is for reverse and the brown wire is for forward. If you're getting full pack voltage to both of these wires when the F&R switch is in the correct position then your controller is your issue.
