club car president 2012 goes fwd but not reverse

[gecoboy]

I think my controller is bad.
Runs ok fwd . When switched to reverse the solenoid engages when pedal is pressed but no movement and solenoid drops after 2 or 3 seconds.
I swapped F1/F2 to motor and it runs ok Reverse and not fwd so proves motor is ok.
Checked at blue and brown wires into controller from fwd/rev switch - get voltage ok as switch is operated.

Is controller bad ?

Does anyone know how to get the cover off the controller ?

Thanks anyone :)

Yes, you have a failed FET in your controller. You proved the motor good when you swapped Fields.
