Filter Block(23FIL,etc.)

To check, disconnect all wires from the filter block on remove from panel. With VOM on

the R x 10,000, touch the leads to the filter terminals to charge the filter. After a few sec-

onds, reverse the meter leads and touch the filter terminal. The VOM needle will deflect and

return to infinity. If this capacitor action is not observed, replace the filter block.

Filter Block(23FIL,etc.)

Filter block test 4K is only to detect an open or shorted filter. If the control has symptoms as

in 1E, interchange 22REC and 25REC and try again. If the problem is corrected, the old

25REC is marginal and should be replaced. If the problem is not corrected, replace both

filters.

1X Choke and Reactor T3-T4

Refer to panel wiring diagram to locate windings. With VOM on R x 1 scale, measure

choke or reactor winding, reading should be less than 1 ohm.
