Coast Continuity Test

  1. With ignition and control switch on, and "SET/COAST" switch depressed, lamps 1, 2, 3 and 4 should be on. Lamps 5 and 6 should be off. If lamp 1 is off, check voltage from brake light switch, check 4-amp in-line fuse in Pink wire, and check Pink, Brown and Dk. Green wires at control switch connector and Dk. Green (14) wire at regulator connector for good connections.
  2. If lamp 2 is off, check speed sensor continuity, check speed sensor terminals to Gray and Dk. Blue wires, and check terminals 2, 3, 5 and 7 (Gray, Dk. Blue and Lt. Green wires are not grounded).
  3. If lamp 3 is off, check brake light switch, check all Brown, Lt. Blue and Lt. Green wire connections. If lamp 4 is off, check terminals 2 and 11 at regulator connector, and check continuity of throttle position feedback rheostat of servo.
