The wedge lock has slotted openings in the forward, or mating
end. These slots accommodate circuit testing in the field by
using a flat probe such as a pocket knife. DO NOT use a sharp
point such as an ice pick.
Service - Voltage Reading
HOLES IN WIRE INSULATION CAN LET IN MOISTURE AND CAUSE SYSTEM FAIL-
URE. DO NOT PIERCE WIRE INSULATION TO TAKE VOLTAGE READINGS.
It has been common practice in electrical troubleshooting to
probe wires by piercing insulation with a sharp point. This
practice should be discouraged when dealing with an
AMPSEAL plug assembly or any other sealed connector sys-
tem. Resulting pinholes in the insulation allows moisture to
enter by traveling along wire strands and could result in sys-
tem failure.
