The most common electrical circuit faults you will encounter when working on bus electrical systems are: open circuits; short circuits; and high resistance. Open Circuit - any break (open) in the current path of a series circuit makes the entire circuit inoperative. In a parallel circuit, only the branch effected by the open is inoperative.

Axial piston pump A10V in swashplate design is used for hydrostatic transmission in open loop circuits. Flow is proportional to drive speed and displacement. By adjusting the position of the swashplate it is possible to smoothly vary the flow. A10V - 52/53 Valve plate End cover Control valve Variable Piston DFR piston Cylinder block Swash plate .
