HIGH TENSION
LEAD WIRE
If a high tension
lead wire
is being replaced,
or a
new coil
and wire
being
assembled, use an
epoxy bond-
ing agent to
secure the
wire into the
coil. Be sure the
opening in the
old coil is
CLEANED thoroughly.
Fol-
low
the instructions
closely for
blending the epoxy.
Heat, such
as
a
heat
lamp,
will
accelerate
the curing
time
of
many
epoxy
compounds.
Check connection
by attach-
ing
continuity meter
leads to points
