3D Rave Test:
1. Pull the black covers off of both rave valves.
2. Refer to service bulletin 2007-11 for a visual picture of the three positions for the valves.
3. With sled off, valves should be in partially open position (atmosphere). Before starting, remove wire safety clips that hold the electrical connectors to the solenoids in place.
4. Start sled, valves should move to closed position (vacuum).
5. With sled running, unplug electrical connector to PTO side solenoid. Valves should move back to the partially open position since you just disconnected the vacuum side.
6. With PTO solenoid unhooked, unhook MAG side solenoid with engine running. Rave valves should pop to fully open position without revving up the engine.
Have FUN!
