Disassembly
1. Insert a 4.8 mm (3/16") wide screwdriver blade
between the mating seal and one of the red wedge
lock tabs.
2. Pry open the wedge lock to the open position.
3. 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.
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 READ-
INGS.
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 con-
nector seals and could result in system failure.
