2A-6 - ELECTRICAL and IGNITION 90-817643R1 DECEMBER 1996
RED Stator with Adaptor and
Ignition Coils
RED Stator DVA Test
NOTE: If using a meter with a built -in DVA, place selector
switch in the DVA/400 VDC position.
NOTE:
Red stators require an adapter module that is
connected between the stator and switch box. With-
out the adapter module, the voltage supplied by the
stator would exceed the voltage capability of the
switch box.

Troubleshooting Procedures
If the DVA reading is HIGH (particularly @ 1000 RPM)
the ADAPTER MODULE is defective.
If the DVA reading is LOW, the stator, adapter module
or switch box may be defective. Refer to the particular
engine model procedure, following, to isolate the prob-
lem.
• Disconnect the BLUE adapter lead from the
switch box.
• Connect the DVA meter between the BLUE
adapter lead and ground.
• Crank the engine (manual or electric).
• If the DVA is normal (190 to 260 volts), the switch
box is defective.
• If the DVA reading is still low, either the stator or
the adapter is defective.
• Disconnect the GREEN/WHITE and WHITE/
GREEN stator leads from the adapter.
• Measure the resistance between the GREEN/
WHITE and WHITE/GREEN stator leads.
• If the resistance is normal (660 to 710 ohms), the
adapter is defective.
• If the resistance is incorrect, the stator is defec-
tive.
