STANDARDS.
The information provided will help isolate the most probable components associated with the difficulty described.
The experienced technician realizes, however, that a loose connection or broken/shorted wire may be at fault
where electrical components are concerned...not necessarily the suspected component itself. Electrical parts
should always be
checked for failure before being returned to the factory.
IMPORTANT:
When replacing blown fuses, the replacement
must be
of the exact rating as the fuse
being replaced. The information provided
should not be
misconstrued as a
handbook for use by an untrained person in making repairs.
