Test 4:
— Testing Capacitor
NOTE:
Consult the owners manual of the meter
you are using for capacitor test procedures.
Test capacitor as shown in Figure 3.50 and compare with
specifications found on capacitor.
Figure 3.50 — Checking The Capacitor
Test 5:
— Check And Adjust Governor
Refer to the appropriate engine manual.
Test 6:
— Check Stator Excitation (DPE) Windings
NOTE:
The excitation wires may be colored or
numbered.The numbered wires are #2 and #6.The
colored wires are blue and red. Be sure not to
confuse the colored excitation wires with the
colored power wires.The excitation wires are the
wires connected to the bridge rectifier or voltage
regulator.
• Set the VOM to its "OHM" scale.
• Connect the test leads to the stator excitation wires
(Figure 3.51).

Figure 3.51 — Checking Excitation Resistance
Measure the resistance and compare it to the nominal
resistance from the appropriate table (Briggs & Stratton
®
Power Products "Portable Generator Rotor/Stator
Resistance Tables Pub. #87971 Rev 6 or later).
A reading of infinity or high resistance indicates an opening
in the excitation winding.
A low reading indicates a shorted stator
winding.
• Connect one test lead to a stator power wire. Connect
the other test lead to one of the stator excitation wires
(Figure 3.52).
Figure 3.52 — Testing For Short Between Windings
A reading of infinity should be measured. A reading other
than infinity indicates a power winding shorted to an
excitation winding.
