Disassembly
5. Insert a 4.8 mm (3/16”) wide screwdriver blade between the mating seal and one of the red wedge lock tabs.
6. Pry open the wedge lock to the open position.
7. While rotating the wire back and forth over a half turn (1/4 turn in each direction), gently pull the wire until the contact is
removed.
Connector Disassembly
NOTE: The wedge lock should never be removed from the housing for insertion or removal of the contacts.
Wedge Lock
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
DO NOT PIERCE WIRE INSULATION TO TAKE VOLTAGE READINGS.
It has been common practice in electrical troubleshooting to probe wires by piercing the insulation with a sharp point. This
practice should be discouraged when dealing with the AMPSEAL plug assembly, or any other sealed connector system. The
resulting pinholes in the insulation will allow moisture to invade the system by traveling along the wire strands. This nullifies
the effectiveness of the connector seals and could result in system failure.
