Correct?
♦
With power source off, check the resistance between the terminals J4 of HF board
(22) and the patch terminal disconnected from J3 (winding of the transformer TF2
on power board (35)). If the winding is broken, replace the power board (35).
♦
Replace the power board (35).
HF COMMAND TEST.
q
HF board (22), connector J1, terminals 7 - 2 (gnd) = fig. 5.2.3, with start button pressed
(command signal for HF board (22), interrupted after approximately 300 msec., for missing
pilot arc current).
YES
NO
♦
Check the wiring between J1 on HF board (22) and CN2 on panel board (31).
♦
With power source off, temporarily disconnect the connector J1 from HF board
(22) and check the resistance between the terminals 7 and 2 of J1 on HF board
(22). Correct value = approximately 200 ohm. If 0 ohm (short-circuit) replace the
HF (22) and panel (31) boards. If >Mohm (circuit broken) replace the HF board
(22).
♦
Replace panel board (31).
♦
Replace the HF board (22).
