that faulty operation is probably

caused by a faulty transformer or

coil. To do this, follow the trouble-

shooting procedures in paragraph 2-

4d.

(2) Do not use the resistance measure-

ments as the sole basis for discard-

ing a transformer or coil as defective.

Resistances may vary from one trans-

former or coil to another because of

broad winding tolerances during

manufacture. The values given in
