Inertia Switch

  1. Turn ignition to "RUN" position. Using a test light, check for battery voltage at both inertia switch wires. If light comes on at both wires, go to IN-LINE FUSE  test.
  2. If light does not come on at either wire, check for open circuit. If light comes on one wire, replace inertia switch and retest system. See Figure .
