Ignition Switch


Any ignition system diagnosis should begin with a visual inspection. The system should be checked for obvious problems.

Do not overlook the ignition switch as a source of intermittent ignition problems.

  • A loose mounting rivet or poor connection can result in erratic spark output.
  • To check the switch, gently wiggle the ignition key and connecting wires with the engine running. If the ignition cuts out or dies, the problem is located.
