Expert advice
Before replacement, check the vehicle's voltage rating (36V) and ensure that the controller in place is a model designed for the Wispeed T855 system. During installation, switch off the power supply, disconnect the battery and check the condition of the connectors and wiring harness (oxidation, bent pins, pinched cables), as a wiring fault can damage a new controller. If in doubt about the exact compatibility with your version of T855, identify the original controller (label, connectors) before ordering.
