Carburetor Switch Test

  1. With the engine at normal operating temperature, turn the ignition off and disconnect 10-way connector from computer. With throttle completely closed, check continuity with ohmmeter leads connected to cavity "7" and ground.
    NOTE: Grounding carburetor switch eliminates spark advance on most systems and provides fixed air/fuel ratio on feedback carburetor systems.
  2. If there is no continuity, check wire from cavity "7" to carburetor switch terminal. Also check carburetor switch for proper operation. Open throttle and check for continuity from cavity "7" to ground. There should be no continuity. If readings are not as outlined, replace carburetor switch.
