Hello, Does anyone have any advice for an Ekko lift? It uses a Curtis 1232E traction controller, and a Curtis 1220EPS steer controller. Using the Curtis handset I keep getting a "steer proximity failure" code, and a "main contactor short/open" code. In the detail list it also says that the motor is -47 Celsius. I have replaced the steer motor, proximity sensor, main contactor and the traction controller. I have checked continuity for ALL wires involved in the circuit. I don't get voltage supplied to the main contactor with key on, seat switch closed, and E stop closed. I have no idea what else I should check? Thanks for any help
