Inspection usually consists of:
(1) Checking for missing or loose parts;
(2) Checking for broken or bent parts, cracked castings or broken pins;
(3) Looking for burnt, charred, scorched or water soaked boxes or wiring;
(4) Smelling for burnt insulation on electrical wiring, and
(5) Feeling for excessive heat generated from electrical or mechanical component
parts.
CAUTION
Be careful when feeling for overheated electrical wiring
and mechanical components.
Shorted wiring and defective
roadwheel bearings can heat up enough to inflict severe
burns.
(6) Manually operating mechanical components for extra play between moving parts.

However, before
attempting any repairs on the starting/charging system of the BFV, these
publications, plus those listed in paragraph 2, on page 3, must be available.
