System 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 Dark Green wire at regulator connector for continuity to connector.
  2. If lamp 2 is off, check speed sensor for correct output voltage. Check Grey and Dark 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 light (and clutch, if equipped) switch adjustment. Check Brown, Light Blue and Dark Green wire connections for continuity between connectors.
  4. If lamp 4 is off, check for defective connection at terminals 2 and 11 on regulator connector. Check operation of throttle position feedback potentiometer on servo.
