Back Probing Connector Terminals

NOTE: Do not insert probes into terminals on
the mating side of any connector. The diameter
of the test probes can damage terminals.
1. Obtain Briggs & Stratton Back Probe Wire
Set (Part No. 19625).
2. Carefully slide metal pin on probe between
the rubber seal and wire insulation on the
back side (wire end) of the connector.
3. Gently push the pin in until it stops. Stop
pushing when the pin "bottoms out," or when
the plastic sheath is very close to the connec-
tor housing.
DO NOT force the pin into the connector as
terminal and/or probe pin damage can oc-
cur. Probe travel may be stopped by contact
with insulation or core crimps. Try again after
removing and re-positioning probe pin.
