Kill Switch Instructions
Thank you for purchasing the Zenoah
™
Kill Switch for your gas
engine.
As you know, the ability to shut down the engine
in an emergency is extremely important. The preferred method
is to close a circuit so the spark is shorted to ground, thus
“killing” the spark and causing the engine to stop, because
there is no “spark.” In this case, the black lead wire from the
coil should be grounded to the engine body. Your Zenoah Kill
Switch is designed in a manner to do just that.(Refer to Figure
for wiring diagram of circuit and components)
Please carefully read and follow the instructions below for install-
ing the Kill Switch into your model.
Mounting Instructions
Note: Examine the switch carefully. Note the On/Off plate has
a tab that positions the switch cover plate correctly
on the switch case.
1) Remove the nut that secures the On/Off plate to
the switch.
2) Remove the On/Off plate from the switch.
3) Select the location for your switch in your model and
carefully drill a 6mm (7/32") hole.
4) Install the switch into this hole from the inside of your model.
Make sure the “star” washer is against the inside surface of
your model and adjust the inside nut to have enough threads on
the outside of the model to install the On/Off plate and exterior
nut.
™
5) The On/Off switch plate is constructed with a tab that inserts
into the alignment groove on the switch. This prevents the
switch plate from rotating out of position during flight.
6) Secure the On/Off plate in position with the external nut.
Note: The side of the switch case is marked “On/Off.”
With the switch cover plate in position, you will note
that the “Off” of the switch plate is over the “On” of
the switch case.
Operating Instructions
With the toggle switch in the “On” position, this means the
circuit is open to ground and the spark is live. With the toggle
switch in the “Off” position on the cover plate, the circuit is
now closed and the spark is grounded, thus allowing no spark
to be generated in the cylinder. In effect, “killing” the engine
operation.
