NOTE: Resistance varies greatly with temperature.
Measurements should be made within an ambient
range of 65 to 85 degrees F

.
NOTE: The stator for manual start engines have a
BLUE/WHITE and a BLACK wire which provide pow-
er for the over-heat horn and overspeed limiter mod-
ule.
Troubleshooting Procedures
ALL MODELS –
If the DVA reading is HIGH (particularly @ 1000
RPM) the ADAPTER MODULE is defective.
If the DVA reading is LOW, the stator, adapter mod-
ule or switch box may be defective. Refer to the par-
ticular engine model procedure, following, to isolate
the problem.
