For my Xbox doco. Stolen from here.
The green box in the top left indicates the typical location of trace corrosion. The sections of interest are labelled in red.
Traces are labelled A to E. A to D are signals, E is power. Power traces should be patched with higher gauged wire. Use 30AWG gauge wire for signal traces.
Connect Trace A from section S1 to section S2.
Connect Trace B from section S1 to section S2.
Connect Trace C from section S1 to section S2.
Connect Trace D from section S1 to section S3.
Connect Trace E from section S4 to section S5.
