3-2. General Inspection.
This chapter applies to
all Leece-Neville models.
a. Regulator Box Assembly (external).
Check
for missing or stripped cover, connector and
mount retainer screws, and voltage adjustment
access plug. Check connectors for signs of arcing,
bent or pushed in pins, broken connectors and
thread damage.
Correct deficiencies by utilization of serviceable
components from unrepairables or requisitioning
components from the manufacturer.
(1) The pin receptacle (J2) is P/N 7064429
FSCM 19207 or MS3102A28-22P FSCM 96906
per MIL-C-5015.
(2) The socket receptacle (Jl) is P/N
7064706 FSCM 19207, an ordnance number for
which there is no equivalent NSN number. An
assembly is available as an ordnance part from
Bendix.

It should be ordered as part number 60-42228-
10S; it will arrive as a complete assembly with the
shell marked 8701337.
b. Regulator Box Assembly (Internal).
I f
water leakage or corrosion is detected, it is pos-
sible that extensive damage has been done and
the regulator cannot be easily repaired. Com-
ponents should be performance tested and re-
tained if acceptable. Check for disconnected or
burnt wires, missing components and replace/
repair as necessary. Carefully remove the transis-
tor mounting plate, noting the position of the
screws, washers and rubber insulators. Visually
inspect the circuit board for burnt components.
Replace the circuit board through cannibalization
if burnt components are found. Carefully reinstall
the transistor mounting plate.
c. Regulator Verification Check.
After per-
forming the above inspection, if the regulator
appears to be in good condition, check its per-
formance on a test stand. If the regulator fails
this check, proceed to the following component
tests.
3-3. Bench Testing.
Figures 3–1 and 3–2 show the
method for testing NPN transistors. These figures
apply to all models in this chapter.
