The manual’s troubleshooting flow is a model for thinking:

Adjusts the maximum current the controller will deliver to the motor. Lowering this value protects delicate gearboxes.

Uses a 16-pin TYCO Mini Universal Mate-N-Lok main connector. Pin Assignments: Pin 3 & 4: CAN_L and CAN_L Termination. Pin 7: KSI (Keyswitch Input). Pin 8: MOSFET Output.

The internal circuit that pulls down the main contactor coil is experiencing an overcurrent or an open circuit. curtis 3501 manual

The Curtis 3501 is designed as a fully customizable, integrated package for electric and engine-powered industrial vehicles. A core feature highlighted in its documentation is its CANopen compatibility

In the world of industrial automation, material handling, and electric vehicle (EV) drive systems, few components are as ubiquitous as the Curtis 3501. This potentiometer-style throttle input device, often referred to as a "throttle pot box" or "accelerator pot," is the critical link between the operator’s foot and the vehicle’s motor controller. Found in everything from scissor lifts and floor scrubbers to golf carts and tow tractors, the Curtis 3501 translates mechanical pedal movement into a precise electrical signal that tells the controller how much power to deliver.

A multi-pin plastic connector manages the logic signals. Standard configurations include:
