Fluke 9100 Calibrator repair

[Machlee]

Our calibrator failed after unhappy connection to seems like an ammeter.
The following components were found burnt and replaced on the "9100 Analog PCB output switching, open sense detect & analog bus":

• K012,
• K003, K004,
• F004

After that the instrument started issuing "SYSТЕМ TRIP: 9508 UNEXPECTED Power amp overload The Program Counter is 48EB0" on boot. And I don't know what to do next.

Have seen http://www.ko4bb.com/getsimple/index.php?id=manuals&dir=06_Misc_Test_Equipment/Datron/Datron_9100 but there aren't the description.

Your job is very difficult...
You can control the LM324 in the bottom corner on the right side of the power board.
