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 mat-
ing 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.
