4-2 1. STUCK RELAY RECOVERY

4-22. If the error m essage shown below appears on the computer's screen during the

Relay Test, the indic",ted relay ol! the indicated pin board is stuck. That is, ,its contacts

remain in the M AKE position even though a BREAK command was sent.

DIAG . ERROR 1

relay

stuck (contacts

w i l l

not BREAK ) .

If a relay is stuck, perform the following procedure :

(1) Note the pin board number and relay number given in the error m essage.

(2) Remove the pin board. Refer to paragraph 4-19. Figure 4-8 shows the pin

board locations.

CAUTIO N

Do not touch the pin board with bare hands.

(3)

Lightly tap the stuck relay with- your finger two or three times. See Figure

4-1 0 for relay locations on the pin board.

(4) Mark the stuck relay with a ball-point pen to indicate its failure history. If

the stuck relay fails more than twice, the pin board should be replaced. Refer

to paragraph 4-19 for instructions on pin board replacement.
