Test TC-15B - Speed Control Power Relay Circuit & Speed Control Solenoid Circuits
- Using an external 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 SC power supply circuit. Perform TEST SC-VER .
- Check brake switch adjustment. See BRAKE SWITCH R & I under REMOVAL & INSTALLATION. 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 .
