ohmmeter
range,
check
the
resistance in
both d irections
between the
black
lead
and each
yellow lead;
total of
4
measu rements.
The
resistance should be
low
in
o
ne
direction
and
more
than
ten
times
as much in the
other
direction.
If
any
two leads
are
low or
high
in
both directions, the
rectifier
is defective
and
the
regulator/
rectifier must
be
repl
aced.

•Prepare a

and
a test

bulb in a
socket with leads.
•Remove
the regulator/rectifier from the frame.
•Connect first
the

between the white/red
lead and the black lead.

•To
apply
12
V to the
regulator/rectifier, connect
both
yellow leads to the battery
terminals.
At this time,
the
bulb should
light.
•The bulb
should
light
even if
the battery polarity
is
changed.
•If the bulb does
not
light
in
either or both

must
be replaced
