The bezel diameter is only a few mil-
limeters larger than the gauge itself.
With that in mind, measure and pre-
cisely mark the gauge location be-
fore cutting any holes!
CAUTION!!!
2. Cut a 2¹⁄₁₆" (52 mm) diameter hole for
the gauge. Make sure the hole is no larger
than 2 ¹⁄₁₆" (52 mm). If the gauge is too
snug, use a file to slightly enlarge the open-
ing. (Diagram A)
3. Slip the mounting bracket over the
mounting bolts on the back of the gauge.
Screw on the accompanying nuts. Tighten
the nuts until the ammeter can no longer
be rotated by hand. (Diagram B)
DO NOT OVERTIGHTEN.
