(2) Replace cover assembly.
(3) Perform bench test procedures.
NOTE
After final repair, check regulator on the
test stand.
If the regulator still does not function correctly
it will be necessary, if local skills permit, to test
each component. All the parts should be checked
with an ohmmeter to make sure that there are no
cracked traces. Traces with hairline cracks will
show good at lower temperatures and will tend
to show open circuit at higher temperatures. If the
board seems good at room temperature, but the
regulator still fails, this could be the cause.
