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 and the capacitors checked

with a capacitance meter. The circuit board traces

should rechecked with an ohmmeter to make sure

that there are no cracked traces. Traces with hair-

line cracks will show good at lower temperatures

and will tend to show open circuit at higher tem-

peratures. If the board seems good at room tem-

perature, but the regulator still fails, this could

be the cause.
