Finding what engine is on your Power Tech generator.

Power Tech serial numbers are usually located on the control box or outside the enclosure.  This depends on the make and model of the generator and when it was made.  On generators pre-1999, it could be stamped on the generator end.

Breaking down the serial number.

Serial numbers usually look something like this: KPS09DDD1234APU

For this part, your Power Tech serial number should start with "KPS" or "CES"
