For starters, 36.9V means the battery pack is only about 60% SoC (State of Charge) and the plates are sulfating as we speak. (38.2V would be 100% SoC) However, that should be high enough to troubleshooting.

Sounds like you have at least two problems.
1. Solenoid not de-energizing
2. Motor not running.

Problem 1. Check the voltage on Pin-5 of the 10 pin plug on top of controller.
It should have pack voltage on it when the pedal is pushed and zero when the pedal isn't pushed.

Problem 2. Connect your DVM test leads between the B- and M- terminals on the controller.
While the solenoid is energized, you should have full battery pack voltage when the pedal is up and near to zero volts when the pedal is down.
