Vacuum Switches: Wagon

To test vacuum switch "A", use an ohmmeter and check for continuity between switch terminal and switch body. Start engine and warm to normal operating temperature. Using an ohmmeter, ensure there is no continuity between switch terminal and body. For vacuum diagram, see VACUUM DIAGRAMS article.

To test vacuum switch "B", use an ohmmeter and ensure there is no continuity between switch terminal and switch body. Start engine and warm to normal operating temperature. Using an ohmmeter, ensure continuity is present between switch terminal and body. For vacuum diagram, see VACUUM DIAGRAMS article.
