IGNITION SYSTEM TESTING
2. Grasp the recoil handle, then crank the engine
over quickly.
3. If the red light on tester illuminates, exciting
coil high voltage output is satisfactory and
indicates there is a problem in the external
ignition coil (see Check External Ignition Coil
Primary and Secondary, page IV-13). If the
red light on tester does not illuminate,
exciting coil high voltage output is not
satisfactory and indicates there is a problem
in the magneto generator (exciting coil, break-
er points, or condenser). Resistance values of
magneto generator components are to be
checked (see Check Breaker Points, Exciting
Coil and Condenser, pages IV-13 and 14).
C heck External Ignition Coil Primary and
Secondary
Equipment Necessary: Electro-Specialties Ohm-
meter Model No. PC2 and Arctic Multi-Tester
II Note: Resistance readings (ohms) are accept-
able within
T
10%.
1. Disconnect the blue wire from the primary
and high tension wire from the external
ignition coil secondary, Fig. IV-21. Make sure
brown wire is connected to external coil
ground.

2. Connect one lead of the ohmmeter to the
external coil primary terminal, and the other
lead to ground, Fig. IV-21.
3. Ohmmeter is to show resistance reading of
1.65-1.85.
4. If resistance is 1.65-1.85, check the external
ignition coil secondary (steps 5 and 6). If
resistance reading is not 1.65-1.85, replace the
external ignition coil because the primary
circuit is defective.
5. Connect one lead of the Arctic multi-tester to
ground and the other lead to the secondary
terminal (where high tension wire connects),
Fig. I V-22. Ohmmeter is to show resistance
reading of 6700-7100.

6. If resistance reading is 6700-7100, external
ignition coil is satisfactory and indicates a
problem in the magneto generator. If
resistance reading is not 6700-7100, the
external ignition coil is to be replaced because
the secondary circuit is defective.
