? My generator is a PE-75-AF the last of a long line of models. Voltages measurement were taken with a Fluke meter. Have TM11-900A which covers my gen set. Found the TM over on smokstak. The house I grew up in was in South Tampa . The ground was a metal pipe driven in the ground near the house. My dad had a meter sold by Sears model unknown. When the Service was upgraded Teco had to install a new transformer on the power pole. The old transformer remained in place for the other houses. My dad passed in 1994 and the old transformer was still in service at that time. The house was built in 1903 and received electric power in 1931. The orginal lighting was with gas. The wiring was ball and tube which was all replaced with the new service. ?
