Note:
Resistance readings and
voltage
checks
can
be
accessed easily for
the
components
in the exciter circuit
A,
a,
c-3 and

by
locating·
the
color coded
wires
at
the
connection points shown
on
the
above
schematic.
When
checking
winding
resistanee
values be
sure
to
lift
both
of
the
component's electrical
connections.
