+24Vdc Power Rap - Xerox workcentre 5335 series Service Manual

A B
Check the +5VDC circuit for a short circuit to frame by referring to Chapter 7 Wiring Data.
Measure for +5VDC on the Main LVPS at the following locations:
• Between P/J503 pin 7 (+) and GND (-)
• Between P/J506 pin 1 (+) and GND (-)
+5VDC is measured at both locations.
Y N
Replace the Main LVPS (PL 18.2).
Check the wire to the applicable component for an open circuit or poor contact by referring to
Chapter 7 Wiring Data.
