Spark Delay Valve System: Testing
- Set an external vacuum source to 10 in. Hg, then connect vacuum source to black side of SDV (Mono Delay Valve) or colored side (all other delay valves).
- Connect a vacuum gauge to the colored side of SDV (Mono Delay Valve) or the white side (all other delay valves).
- Apply vacuum to SDV and check the time it takes for gauge to read from 0 to 8 in. Hg while applying a constant 10 in. Hg.
- The minimum and maximum time for valve to reach 8 in. Hg should be as shown in following table:Spark Delay Valve Specifications (Time In Seconds)
