System Electrical Continuity

  1. With ignition and control switch on, lamps 1, 2, 3, and 4 should be on. Lamps 5 and 6 should be off. If lamp 1 is off, check for blown fuse in brake light switch to control switch circuit. Check Red, Brown and Green wires at control switch for continuity to switch. Check Dk. Green wire (14) at regulator connector for continuity to regulator.
  2. If lamp 2 is off, check speed sensor for correct output voltage. Check Gray and Dk. Blue wire at speed sensor connector for continuity to regulator connector. Check terminals 2, 3, 5 and 7 at regulator connector for proper connection to wires.
  3. If lamp 3 is off, check brake and clutch switch adjustment. If lamp 4 is off, check for defective connection at terminals 2 and 11 on regulator connector. Check operation of throttle position feedback rheostat on servo.
