Reinstall the wires on the terminal studs in the same polarity. Refer to Step 7. Install new 6D-5801 Locknuts (5). Torque locknuts to 1.3 N m (1 lb ft). Ensure that the wire terminals do not touch each other after the locknuts have been tightened. Note: Use caution when applying torque to the new 6D-5801 Locknuts (5). The stud is made of brass and will break if the torque value is exceeded. An over torque will take place if the nut is seated and rotated beyond 1/8 turn.
Reinstall the EMI filter, if equipped.
