12.Connect one test lead to TX terminal 1. Connect the
other test lead to TX terminal 7. INFINITY should be
measured.
13.Connect one test lead to TX terminal 10. Connect the
other test lead t TX terminal 7. INFINITY should
be
measured.
RESULTS:
For steps 5, 6, and 7, replace transformer if an open
is indicated, or if the resistance value indicated is
zero. If the resistance value is not within the
approximate range, proceed to test 65.
For steps 8 through 13, replace the transformer if it
fails any of these steps.
