Check for voltage drop between battery positive and pin one at the curtis controller.
It should be less than 0.7v when driving and lowering.
Common high resistance places are the keyswitch the spade connectors for the onboard charger, and and the drive tow switch and connections if it has.
Any spade connection should be suspect as well.
