Step 4: Remove the
Existing Field Circuit Board
1. Remove the wires from connectors UF, UF1, VF and VF1.
2. Remove the six screws and washers that secure the Field board to the
Field SCR and Dual Diode Modules and remove the Field board.
Step 5: Install the New
Field Circuit Board
Install the new Field circuit board in reverse order of removal as detailed in
Step 4:

•
Tightening torque for the screws connecting the Field board to the Field
SCR and Dual Diode Modules is 2.5…4.0 N•m (22…35 lb•in).
•
Inspect the existing X3 and XFCD cables for burn marks, cracks or loose
connectors. If necessary, replace the cables on the Field board with the
new cables provided.
