Hints:
- removing of Auxiliary Power Supply 15.14.271 is not required to perform checks listed above
- to ease measurements, PZ_- , +12VAUX , PZ_+ signals are electrically connected to CNB/9, CNB/10, CNB/16 respectively.
* Note: fuses are located on Aux. Power Supply PC board 15.14.271 (see related section below).
