Some Petroleum Quality Analysis Systems-Enhanced (PQAS-E), NSN 6640-01-547-1760 (EIC-ZBX), LIN P25743 have newer SST25 generators. The newer-version SST25 generators install correctly but function differently internally.
 
SST25 generators sold after June 2019 have internal actuators, while the older models use the advanced proportional engine control system (APECS). The wiring system of the newer generators is not covered by the PQAS-E TMs.
 
Serial numbers for the affected newer generators are provided below:
