B.4.3.

Power Output to the Displays

The data output from the computer to the displays cannot be readily field tested.
The +4.8 to 5.2 VDC supplied to the displays from the computer, on the other
hand, can be tested.  To test the 5 volts to the displays perform the following steps:

Set your meter on the 20 VDC scale.

Connect the common lead of your meter to pin 2 of either the J4 or J5
connector (depending on whether the side 1 or side 2 display circuitry is
being tested) on the computer (see Figure B-13).

Connect the positive lead of your meter to pin 1 of the J4 or J5 connector
on the computer.

Your meter should read +4.8 to 5.2 VDC if not the computer is defective.
