EZGO DCS txt won't go forward

[Psellers]

Thought id jump in here to see if I could get any help with a similar issue. I thought I had a bad controller also I sent my control in to FSIP and got a reman one. I then got it back and during my trouble shooting rotated the plug to the tow reverse switch 90 degrees and let the factory smoke out of the control, I again sent my control back to them again and got another remanded one

. I have reverse when I press the throttle and when I switch to forwards I have a slight hum from the motor but nothing else. Ive switch f1 and f2. when I do that I still only get reverse but I get reverse when I've elected forwards if that makes since. If all wiring is correct and I select forwards and un plug the forwards switch and then jump the switch between the two wires going to the switch I get the same result, just a slight hum from the motor with no forwards.
