or resistors between S7902A and S7902B

are defeotive.

a. use the wiring diagram (fig. 11) and

oheck for broken jumper leads between

switch oontacts and between decks. Check

also for oold solder joints, or large masses

of solder whioh maybe shorting two con-

tacts together. Cheek for open or shorted

switch oontacts.

b. Use the ohart below and oheck S7902A

and S7902B for open resistors or for re-

sistors with ohanged values. Remove all

plug-in assemblies (para 37) before meas-

uring resistances.
