Connect one test lead (2) to each pin, of connector (3), one at a time.
(d)
Connect other test lead to outer casing of connector (see Cable Schematics for details).
(e)
Cable is good if Multimeter reads INFINITY/open. Cable may be defective and must be replaced if
Multimeter reads other than INFINITY/open.
(f)
Repeat steps (c) and (d) until all pins have been checked.
(3)
