Control Switch

  1. Disconnect 6-way connector at amplifier. Check battery voltage at Light Blue/Black hash wire when "ON" switch is depressed. Battery voltage should be available from Light Blue/Black hash wire leading from control switches.
  2. Connect an ohmmeter between Light Blue/Black hash wire and ground. Check wire for continuity to ground with "OFF" switch depressed. If resistance higher than 1 ohm is found, the wiring, slip rings or switch is at fault, or steering column may not be properly grounded.
  3. To check steering column ground, connect an ohmmeter between a good body ground and steering column upper flange. Resistance should be less than 1/2 ohm. Rotate steering wheel, and check flexible coupling resistance. If resistance higher than 3 ohms is noted, clean horn brush contacts and ground brush.
  4. A resistance less than 1 ohm must be obtained before performing the remaining tests. With ohmmeter connected between Light Blue/Black hash wire and ground, depress "SET-ACCEL" switch. A reading of approximately 680 ohms should be indicated on ohmmeter.
  5. Depress "COAST" switch and a reading of approximately 120 ohms should be indicated on ohmmeter. Depress and hold "RESUME" switch. A reading of approximately 2200 ohms should be indicated.
