3. Apply +12VDC to the two smaller terminals. You
should hear a click and get continuity between the
two big terminals. If you disconnect the battery,
the solenoid should again “click” and loose
continuity between the big terminals.

Ignition Switch
Purpose
There are two types of ignition switches used. The
recoil start models use a simple off/on type of switch.
The electric start models use a three position switch
with multiple circuits.
Location
The ignition switch is located on the control panel
within easy reach of the operator.

How It Works
On recoil start models the ignition is a simple on/off
switch. One wire connects to chassis ground and the
other to the magneto. When the key is turned off the
switch closes and grounds the magneto. Turn the key
on and the ground is disconnected.
Electric start models require a switch with three
positions; OFF, RUN, and START. The START position
is spring loaded so the cylinder automatically returns to
RUN once the key is released.
We use three different switches on electric start
models. Two have five terminals and the other has six.
Terminals of the ignition switch are viewed from the
back side (terminal end) of switch (Figure 221, Figure
222, Figure 223).
