CAUTION

Remove power before making resistance checks.

b. DC Power Resistance Checks. Resistance checks are made at two points on dc power input

connector J7. Check for an open circuit between connector pins J7-E and J7-B. Verify that less than 0.10 ohm

is present between connector pin J7-B and the chassis ground stud.

c. AC Connectors Neutral and Ground Checks. Table 5-2 lists measurements and data for the ac power

output at connectors J2, J3, and J6. Each line lists related neutral and ground connector pins that are used for

resistance measurements. The data is used to verify the following conditions:

(1) More than 1.0 megohm is present between each related neutral and ground connector pin listed.

(2) Less than 0.5 ohm is present between all neutral connector pins listed.

(3) Less than 0.5 ohm is present between the chassis ground stud and each ground connector pin listed.

d. DC Connectors Ground Checks. Table 5-3 lists measurements and data for the dc power output at

connectors J4, J5, and J9 thru J11. The data is used to verify that less than 0.5 ohm is present between the

chassis ground stud and each connector pin listed.
