"Won't turn on" Electric Rotor
Remove PRS retaining nut, internal and valve. Using a portable compressed air/water tank and long blow tip, clear exhaust tubing by blowing down through the center hole in PRS housing. Clear high pressure tubing by blowing down through the manual port. Reverse the procedure and blow up from bottom of case through exhaust hole and valve probe. Rinse all components, reassemble and test rotor.
If the Rotor turns on then the problem is resolved.
