7. Cut the cable going to the stator at the splice.
8. Connect one of the multimeter probes to the cable
for the carbon brush. Connect the other one to the
cut off cable going to the stator.
9. A disassembled stator is best examined by
measuring the stator and the windings one at a time.
Connect one of the measurement cables to the gray
cable with a cut off splice (A). Connect the one to
one of the two black cables for the circuit breaker
(B). Do the same on the other black cable.
When a test is made with the stator on the product, the
inductance must be 10-12 mH. Resistance must be
around 0.2-0.3 Ω.
If the stator is broken, an inductance test gives 0 mH. A
resistance test gives a maximum value.
If some windings are short-circuited, the inductance will
decrease. If the value is 30% (7 mH) below the typical,
the stator must be replaced.
When a test is made on a disassembled stator, the
inductance must be around 4–4.5 mH. Resistance
values must be around 0.5–0.6 Ω. Large differences
between the windings means the stator is defect
