Default Controller, no Voltage on Field Terminals

Still fighting with this 1997 Club car regen 1 that has been OEM upgraded to Regen 2.

Motor works with power directly connected to motor terminals (bypassing controller) and I finally got the solenoid to click.

Now I have Voltage on the controller terminals connected to A1 and A2 (the big wires).

However, I have no voltage on the terminals connected to F1 and F2. The voltage at A1 and A2 is battery level voltage and does not vary with pedal.

I am guessing this is a potentiometer issue or is could there be another culprit I am missing?

Does the field voltage control speed or is the armature voltage also varied for speed control?

IT won't run at all without field voltage. Speed is mostly regulated by armature voltage. Field voltage starts at max to give max torque - then it drops when you get up to speed.
Sounds like your controller is toast.

I think you were right, I switched to a third controller and that solved my problem.

Still not 100% sure though, I have three of these identical carts with same controller and none of the three have the same wiring connections/colors, LOL.
