    Wiring diagram attached. Can anyone explain the Operation Or Signal/ Boot cycle of the Connection?
    This connector seems to have a lot of fuser related pins. I would try to start machine without fuser.

            Thanks! I've isolated the Fusing Unit, but no response!

            What about the following connectors?

            1. POWER _MONITOR
            6. DRIVE_RY_REM
            7. MC_P_OFF
            8. SLEEP_STATUS_REM
            9. INPUT_POWER_MON
            10. ZERO_CROSS

            Also please check the connector design difference between BH450i and BH550i/BH650i

                FYI, in the last 5 days I've had 2, new in box, C450i fusers take out a DC power supply and a fuser drive assy. Not sure what they are doing down at the doughnut factory...E

                    Sounds fantastic: sarcasm
                    KM were at the top in my list but last year started going down in a fast lane.

                            Had a similar issue last year at a school account BH 550i after replacing most electrical parts control panel storage board Power supply CPU etc still would not boot but always hear clicking sounds. The last part replaced was MFP main board it finally booted all systems working as normal after.
