Test TC-15B: Speed Control Power Relay Circuit, S/C 12V Driver Circuit & Speed Control Solenoid Circuits
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- Using an ohmmeter, check resistance of speed control brake switch output circuit between brake switch connector and speed control servo 4-pin connector. See SPEED CONTROL SERVO CONNECTOR WIRE IDENTIFICATION table and BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION table. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open brake switch output circuit. Perform TEST VER-4A .
- Check brake switch adjustment. See appropriate DISC & DRUM article in BRAKES. If brake switch adjustment is okay, replace brake switch. Perform TEST VER-4A . If brake switch adjustment is not okay, adjust brake switch as necessary. Perform TEST VER-4A .
