Stator Ohms Test-Alternator Coils
Only
NOTE: Stator can be tested without removing from
engine.
1. Disconnect both yellow (stator leads) from termi-
nals on rectifier (or terminal block) or disconnect
bullet connectors from voltage regulator.
2. Use an ohmmeter and perform the following test.
IMPORTANT: If stator is mounted on engine,
black stator lead (if provided) must be grounded
to powerhead when testing.
3. Replace stator if readings are outside ranges
shown.

*DC Resistance of these windings generally is less than 1.5
Ohms. If a reading resembling a short is obtained, this would
be acceptable.
