Replacement and Functional Testing

• Before replacement, disconnect the vehicle power. Note the connections and install the new switch in the same intended location without pinching the wiring.
• Check that the buttons or switch operate without sticking and that the connector is properly engaged. The handlebars must be able to turn without stretching the cable.
• Test every function individually before riding. When contact is interrupted, check the connector and wiring as well, as the fault is not necessarily in the switch itself.
