Speed Control Relay Test

  1. The speed control relay is mounted close to fuse panel under instrument panel. Check all electrical connections before testing relay. Turn ignition switch on and move slide switch to "ON" position. Using a suitable test lamp, ground one test lamp lead and touch other to each connector at relay. Test lamp should light at each connector wire except ground.
  2. If test lamp lights on the white and violet connectors but does not light on red connector, replace relay. If test lamp does not light on white and violet connectors, check fuse, wiring harness and power source connection.
