Test TC-82B - Speed Control Solenoid Circuits Or Speed Control Power Relay Circuits

NOTE: Perform TEST TC-82A  before proceeding. For connector terminal ID, see CONNECTOR IDENTIFICATION . For component location see WIRING DIAGRAM .
  1. Using an external ohmmeter, check resistance of S/C on/off switch sense circuit (Yellow/Red wire) between brakelight switch connector and S/C servo connector. If resistance is more than 5 ohms, repair open S/C on/off switch sense circuit and perform TEST SC-VER . If resistance is 5 ohms or less, go to next step.
  2. Check brakelight switch adjustment. Adjust brakelight switch as necessary and perform TEST SC-VER . If brakelight switch is adjusted properly, replace brakelight switch and perform TEST SC-VER .
