AC VOLTAGE OUTPUT TEST
Reason:
To measure engine alternating current voltage output to
determine stator condition.
Equipment:
• Multimeter
Connections:
1. Disconnect engine connector (A).
2. Set multimeter to read AC voltage.
3. Connect red multimeter lead to black wire from
engine connector at terminal (B).
4. Connect black multimeter lead to chassis ground.
Procedure:
1. Start and run engine at 3600 rpm while watching
multimeter.
Specifications:
AC Voltage Output (3600 rpm): . . . . . . . . . . . 14 Volts
Results:
• If reading is less than specifications, see Briggs &
Stratton service manual for electrical system
repair.

STARTER SOLENOID TEST
Reason:
To determine if starter solenoid or starter is defective.
Equipment:
• Jumper wire
Connections:
1. Put transaxle in neutral. Move key switch to off
position.
2. Engage park brake.
3. Disconnect and ground spark plug lead.
4. Disconnect purple wire from small starter solenoid
engagement terminals (A).
Procedure:
1. Connect jumper wire to positive battery terminal
and briefly jump to bare small starter solenoid
engagement terminal (A).
Results:
• Starter runs: solenoid is good, check circuit wiring.
• Starter does not run: go to step 2.
2. Connect jumper wire between starter solenoid large
terminals (B and C).
Results:
• Starter runs: Replace solenoid.
• Starter does not run: Check battery cables then
replace starter.
