Carburetor Switch Test
- Turn ignition off and disconnect 10-wire connector from computer. With throttle completely closed, check continuity with ohmmeter leads connected to cavity 7 and ground.
NOTE:
Grounding carburetor switch eliminates all spark advance on most systems.
- If no continuity is read, check wire from cavity 7 to carburetor switch terminal. Also check carburetor switch for proper operation.
- Open throttle and again check for continuity from cavity 7 to ground. There should be no continuity. If readings are not as previously described, replace carburetor switch.
NOTE:
After performing carburetor switch test, perform tests on the spark control system and fuel control system.
