Disassembly
1. Insert a 3/16" (4.8 mm) wide screwdriver blade between
mating seal and one of the red wedge lock tabs.
2. Pry wedge lock to the open position.
3. While rotating wire back and forth over a half turn
(1/4 turn in each direction), gently pull wire until
contact is removed.
NOTE: Wedge lock should never be removed from housing
for contact insertion or removal.
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 is common practice in electrical troubleshooting to
probe wires by piercing insulation with a sharp point. This
practice should be discouraged when dealing with the
AMPSEAL plug assembly, or any other sealed connector
system. Resulting pinholes in insulation allows moisture to
invade the system by traveling along wire strands. This
nullifies effectiveness of connector seals and could result
in system failure.
