midpoint of the trouble brackets. Each additional check should eliminate as
much of the system as possible, following closely the "halfsplit"
principle. Convergent circuits can be checked by checking each or every
input. Divergent circuits can be checked by checking any output. Switching
circuits can be checked by seeing which circuits are affected by the
trouble. Feedback circuits can be checked by modifying the feedback and
checking the output. These are general rules to follow when troubleshooting
any type of system, but they are logical and efficient, and very easily
adapted to suit any situation.
