Test TC-15B - Speed Control Power Relay Circuit & Speed Control Solenoid Circuits
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS .
- Using a ohmmeter, check resistance of switched Speed Control (SC) power supply circuit Dark Blue/Red wire between brake switch connector and SC servo connector. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open switched SC power supply circuit. Perform TEST SC-VER .
- Check brake switch adjustment. See appropriate article in the BRAKES section. If brake switch adjustment is okay, replace brake switch. Perform TEST SC-VER . If brake switch adjustment is not okay, adjust brake switch as necessary. Perform TEST SC-VER .
