1o 'loff'
position,
thus
preventing
electric
surges in the armature circuit
which

lnstallation
lnstructions
Mounting
Switch should be located as close to
the batteries as
possible
with regards
to convenience of operation. The battery and starter
cable
should be as short as
possible.
There are three mounting
positions:
1.
Surface
mounting with the
wires
going
through the
openings
at
the base of the switch.
2. Surface mounted with
a
hole in
the mounting surface to
permit
wires
to come through at the back of the switch.
3. Recessed mounting of the
switch through a hole in the
mounting
surface.
For surface
mounting,
place
the switch in the desired location and, using
the switch as a template, locate the four mounting
holes. Then
drill four equally-spaced #12 holes on 4
3/8" centers.
