Many times the problem is merely a burned slip-on connector due to a poor crimp joint, or weakened connection. If the switch is in good working order, the repair can be made by cleaning the terminals, and replacing the burned connector. Or, simply cut off the burned connectors and solder the wires directly to the switch terminals. Carefully remove the harness leads from the switch terminals. Pry them loose if necessary, but do not exert too much force, or the terminal may break right out of the switch.
Many models use a connector with a locking clip in the center of the receptacle terminal.
This extruding lever must be pressed down while gently pulling the connector off the terminal. R X 1 As shown in the picture, place one meter probe on the COM terminal and the other probe on the N.O. terminal. However, switches with just two terminals, both of which come out the back, do not click when actuated, and neither do switch modules. Move the probe from the N.O. terminal to the N.C. terminal. The other probe remains on the COM terminal.
