• Connect one test lead to a stator power wire. Connect
the other test lead to one of the stator excitation wires
(Figure 3.42).
Figure 3.42 — Testing For Continuity Between Windings
NOTE:
On units that have two board regulation,
the stator power and excitation windings are
connected internally. On these units, a reading of
continuity would be a normal condition.
(See schematic on page 22, figure 2.6).
• Connect one test lead to an excitation wire. Connect
the other test lead to a good metal
ground (Figure 3.43).

Section 3 • Generator Diagnostics and Adjustments
A reading of "infinity" should be measured. A reading other
than infinity indicates a winding
shorted to ground.

: — Testing Stator AC Power Windings
Testing Single Voltage Type Power Winding
• Set a VOM to its "OHM" scale.
• Connect the meter test leads across the (AC) power
wires. (Wire #11 and wire #22 or blue and red wires
(Figure 3.44).
Figure 3.44 — Checking Power Winding Resistance
Measure the resistance and compare it to the nominal
resistance from the appropriate table
(Briggs & Stratton Power Products
Rotor/Stator Resistance Tables Pub. #87971 Rev 6 or later).
A reading of infinity or high resistance indicates an opening
in the stator winding.
A low reading indicates a
shorted stator winding.
