VVIRING CIRC UIT TESTING

10. Now, remove the ohmmeter lead from the
black wire terminal and connect it to the
black wire having a white tra cer, Fig. I V-37.
Move dimmer switch to high beam. Ohm-
meter is to register OPEN.
11. If the ohmmeter registers as explained in steps
9 and 10, the dimmer switch is acceptable. If
ohmmeter does not register as explained in
steps 9 and 10, the dimmer switch is defective
and is to be replaced.
II
Note: The switches have all been checked at
this time. If a lighting problem still exists,
the only possible defect is in the wiring circuit
harness having a lighting problem. Replace the
appropriate wiring harness to remedy the lighting
problem.
Check Magneto Alternator
Equipment Necessary: Screwdriver Having a
3/16-lnch Blade and Electro-Specialties Ohmmeter
Model No. PC-2
1. Shut the engine off.
2. Disconnect the main wiring harness from the
engine connector plug.
3. Remove the green wire and yellow wire from
the engine connector plug, Fig. I V-38, using a
screwdriver having a 3 / 16-inch blade. Also,
remove the yellow wire having a black and
green tracer, and the green wire having a black
tracer from the engine connector plug, using a
screwdriver having a 3/16-inch blade.

4. Separate the wires from the terminal end
pieces.
5. Connect one lead of the ohmmeter to the
yellow wire, and the other lead to the yellow
wire having a black and green tracer.
Ohmmeter is to register 0.28-0.31 ohms.
6 . I f the ohmmeter registers 0.28-0.31 ohms, the
100 watt lighting coil is acceptable (proceed
to step 7). I f the ohmmeter does not register
0.28-0.31 ohms, the 100 watt lighting coil is
defective and is to be replaced (see Magneto
Generator Disassembly, page IV-26).
7. Connect one lead of the ohmmeter to the
green wire, and the other lead to the green
wire having a black tracer. Ohmmeter is to
register 1.70-1 .85 ohms.
8. If the ohmmeter registers 1.70-1.85 ohms, the
23 watt lighting coil is acceptable (proceed to
step 9). If the ohmmeter does not register
1.70-1 .85 ohms, the 23 watt lighting coil is
defective and is to be replaced (see Magneto
Alternator Disassembly, page IV-26).
9. The lighting coils have now been checked for
proper resistance. If the resistance values were
as specified, the air gap between the flywheel
magnets and coil pole shoes is contributing
to the low voltage output of the magneto
alternator (see Set I nduction Coil Air Gap,
page IV-28) .
II
Note: If voltage output of the magneto
alternator does not improve, even after all the
preceding tests are taken, the flywh eel magnets
may be weak. Compare the magnetic attraction of
the old flywheel against the attraction of a new
flywheel. I nstall a new flywheel if old flywheel
magnets do not seem to be strong enough.
