AWA Troubleshooting
clipped together. If one or more of the leads indicates a much different value the
following conditions may exist:
Broken test lead, verify test lead integrity with an ohm-meter, check for loose or broken
test leads, clips.
Pitted high voltage relay contact on the indicated test lead, re-run the test several times. If
a value change is seen, the relay may need to be replaced.
Welded high voltage relay on the suspect test lead. If connected to live AC circuits, these
relays may be damaged or welded in the N.C. position.
14. AWA always reports 2001 ohms on the
resistance balance test; HiPot and surge
tests appear to work normally.
a. In AWA Series II tester, it was possible for the 80-125 board to be unseated after
rough handling. Remove the top lid, and verify the presence of the 80-125 board in
it’s mother board slot. Also verify the presence of the Neoprene foam stripping on the
top of the case that should hold the card in place.
b. Bad or damaged 80-125 winding resistance board.
c. Broken or damaged test leads
d. Faulty 80-100 AD/IO
15. AWA resistance test works normally,
HiPot and surge do not.
a. In this case, it is almost always a problem with the 80-124 HVDC board; it does not
influence the resistance tests very much. For example: on occasion the DC/DC
converter used on this card has been knocked out of it’s socket due to rough handling.
Replacement fixes the problem.
b. Damaged or welded Surge/Hi-Pot relay:
