REPAIRS AND MAINTENANCE (continued)
By removing possible defective modules from the circuit you will arrive at the
point where connecting a system ribbon to a particular module that is connected
to nothing else causes the system to malfunction. This pinpoints the problem to
that card. Schematics for each PC card are supplied in the next section.
Easier to spot are single failures where a single circuit stops working without
affecting other modules. Again, the only way to show definitely that the problem
is in a single module is to disconnect it from everything except a “known good”
input.
