PA Resistance Checks
1.
Using a digital multimeter, check the continuity across fuse F1 on the suspect PA PWB.
If the measurement is an open circuit, replace the PA PWB (see
If the measurement is short circuit (near 0
), proceed to
.
2.
Using a digital multimeter, measure the resistance between each gate lead of the FET and the
metal flange of the FET.
If the measurement is less than 8 k
, replace the PA PWB (see
If the measurement is between 8 k
and 17.5 k
, check the other PA PWBs for a failure. If
none of the other PA PWBs have failed, replace the original suspect PA PWB.
If the measurement is greater than 17.5 k
, proceed to
.
3.
Using a digital multimeter, check the continuity between each drain lead of the FET (positive meter
probe) and the metal flange of the FET (negative meter probe).
If the measurement is open circuit, the PA PWB is OK and does not require replacement.
Continue troubleshooting and suspect a problem with an associated PWB.
If the measurement is not open circuit, replace the PA PWB (see
