Power Requirements
(1)
Voltage Change Kit Removal
On 28 V dc installations a voltage changeover kit (P/N 050-01578-0000)
was installed. The 10-Ω, 55-W, resistor, (132-00113-0004) must be re-
moved from pin 11 in the wiring harness.
(2)
Additional Supply Line (Recommended but not required)
Add pin 12 to support the additional current (see
details).
(3)
Change the harness fuse from 3 A to 5 A current rating.
(4)
The RFI Suppression Adaptor (P/N 071-02010-0000) must be removed
if it was installed.

Additional Features
The following pin may be added to obtain the additional feature:

MOLEX CONNECTOR ASSEMBLY PROCEDURE
The KT 76C uses a special connector that mates directly with the printed circuit board inside the
unit (see
Figure
2-1). Assemble the connector using the following procedure:
A.
Solderless Contact Terminal Assembly using Molex Crimper
Refer to instructions in
B.
Solderless Contact Terminal Assembly using Pliers
(1)
Strip each wire 5/32 inches for contact terminal (P/N 030-01107-0024).
The last two digits of the contact terminal part number indicates the num-
ber of terminals furnished.
(2)
Tin the exposed conductor.
(3)
Using needle nosed pliers, fold over each conductor tab, in turn, onto the
exposed conductor. When both tabs have been folded, firmly press the
tabs against the conductor.
(4)
Repeat step (3) for insulator tabs.
(5)
Apply a small amount of solder (using minimum heat) to the conductor/
tab connection to assure a good electro-mechanical joint.
C.
Contact Insertion into Molex Connector Housing
(1)
After the contact terminals have been installed on the wiring harness, the
contact terminals can be inserted into the proper location in the connec-
tor housing (P/N030-01094-0066). The terminal cannot be inserted up-
side down. Be sure to push the terminal all the way in, until a click can
be heard or felt.
(2)
The self-locking feature can be tested by gently pulling on the wire.
D.
Extraction of Contact from Molex Connector
(1)
Slip the flat narrow blade of a Molex contact ejector tool, HT-1884 (
eywell
the connector. By turning the connector upside down one can see the
blade slide to the stop.
