- Air or vacuum leaks. Check hoses, tubes and flange joints for leaks.
- Restricted air inlet. Check air filter and air induction system.
- Supercharger not rotating. Check drive belt. Remove outlet adapter. Inspect rotors for damage and seizure. Replace supercharger if rotors are damaged.
- By-pass actuator not closing. Check valve and actuator rod for restriction. Ensure actuator rod rests against lever stop when vacuum is less than 3 in. Hg.
- Insufficient flow from supercharger. Remove outlet adapter. Ensure rotors turn when pulleys are rotated. Replace supercharger if rotors do not turn.
