In a dynamoelectric machine having a housing, a rotatable commutator within the housing, a brush contacting the commutator, an electrically conductive brush holder affixed to the housing and supporting the brush, a brush pigtail connected to the brush, an electrical conductor connected to the pigtail at a junction, and a flange extending from the brush holder, the flange having a hole formed therethrough and spaced opposite first and second surfaces, a support device extends from the flange and passes through the hole for supporting the junction of the pigtail and the conductor. The support device includes a first insulator which electrically isolates the junction from the flange at the first surface of the flange. A second insulator electrically isolates the junction from the flange at the second surface of the flange. A third insulator electrically isolates the junction from the flange in the hole.
