- Remove vacuum hose at distributor and connect a vacuum gauge to hose. Place gauge so it can be read from drivers seat. Run engine until thoroughly warm (about ten minutes). With transmission in Neutral, depress throttle slightly. Vacuum should be present.
- With throttle still depressed, shift transmission into first gear. No vacuum should be present. If vacuum reading is constant at all times (caused by closed circuit), check for grounded wire in circuit, thermal override switch stuck closed (activated) or transmission switch stuck closed.
- If no vacuum was present during test (caused by open circuit), check for blockage in vacuum lines, carburetor fitting or carburetor. Also check for blown radio fuse, broken wire in system, or solenoid coil wire broken or open. Check all hoses for proper routing and good connections.NOTE: This test also checks PVA system.
