Place #1 spark plug wire on #1 cylinder’s spark plug and #2 spark
plug wire on #2 cylinder’s spark plug (just to the right of #1 when
looking at the front of the engine). Continue this progression until
you have all spark plug wires installed.
Install the grounding leads that are sleeved to the spark plug wires
by first attaching the lead to the upper most screw on the intake
tube
’s brass retainer ring. Next install the other end of the
grounding lead wire to the ground wire on the CDI ignition box. This
is a black wire protruding from the ignition box with a ring connector
affixed to the end of the wire. All nine grounding leads need to be
attached to the ring connector on the ignition box ground wire using
a small bolt, 2 washers, lock washer and nut. On later models, the
ignition box has a nine lead extension with bullet connectors for
greater ease of rigging.
The CDI ignition is powered by a 6 to 8.4 volt battery. 2000 to 5000
mAh NiCad, NMH or LiPo battery is recommended. As stated
above, one battery can be used if it is a high capacity battery (5000
mAh) for both the ignition and fuel pump (not to exceed 8.4 volt). If
using one battery, it is recommended to check the amount of charge
in the battery between flights. A separate switch (from the fuel
pump) is recommended for the ignition system. Also recommended
is transmitter operated switches (one for the ignition & one for the
fuel pump) that will allow you to kill the engine remotely in case of an
emergency. See diag
ram below for the engine’s suggested fuel and
ignition rigging in your airplane.
