17.33. The engine harness connector on the White
tractor has alternator and safety circuit compo-
nents. See Figure 17.33.

• The red wire in the thermally insulated conduit
near the starter motor leads to the after-fire sole-
noid. It receives power from the battery and the
alternator through red jumper wire.
• The green wire in the thermally insulated conduit
near the starter motor leads to the magneto pri-
mary winding connection.
of the connection is the yellow wire that provides
engine shut-down capability through a variety of
possible ground paths.
• The yellow wire in the PVC conduit that emerges
from under the engine shroud connects to the
blue wire in the tractor harness, providing dedi-
cated power for the lights.
• The red wire in the PVC conduit that emerges
from under the engine shroud connects to paired
red wires in the tractor harness. One feeds
power to the B terminal on the key switch, while
the other provides power to the after-fire sole-
noid when the engine is running.
• Refer to the engine manufacturer's specifica-
tions to test starting and charging systems.

• The red wire in the engine harness contains a
diode. It provides D.C. power to paired red wires
in the tractor harness. One feeds power to the B
terminal on the key switch, while the other pro-
vides power to the after-fire solenoid when the
engine is running.
• The orange wire carries unregulated, non-recti-
fied alternator output to the blue wire in the trac-
tor harness, providing dedicated power for the
lights.
• Refer to the engine manufacturer's specifica-
tions to test starting and charging systems.
