6. Remove the cover from the control pod and inspect all visible major
components, including: circuit boards, wire harnesses, fiber-optic cables,
and connectors. If any components show evidence of burn marks or
breakage, replace the damaged components without further testing.
• For frame 5, see step 3 only in Remove the Main Control Circuit Board
on page 57
.
• For frame 6, see step 3 only in Main Control Circuit Board
Replacement on page 77
.
• For frame 7, see Remove the Control Pod Cover on page 98
.
• For frames 8…15, see Control Pod Cover Removal on page 146
.
7. For frames 5 and 6, inspect the power feedback circuit board. If any
components, particularly the resistors, show evidence of burn marks or
breakage, replace the circuit board without further testing. For frame 5, see
page 67
. For frame 6, see page 87.
