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 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 sys-
tem. The resulting pinholes in the insulation will allow mois-
ture to invade the system by traveling along the wire strands.
This nullifies the effectiveness of the connector seals and
could result in system failure.
