Briggs & Stratton CE8069 10 & 16 Amp DC Regulated Alternator, Test Alternator Output, receptacle

1.Connect stator wire harness to regulator- rectifier.

2.Insert RED test lead into 10 Amp receptacle in meter.

3.Insert BLACK test lead into COM receptacle in meter.

4.Rotate selector to DC Amps position.

5.Attach RED test lead clip (A, Figure 27) to RED DC output terminal on regulator- rectifier.

6.Attach BLACK test lead clip (B) to positive (+) battery terminal.

Figure 27

7.Run the engine at 3600 RPM. The output should be:

•3-5 Amps - 5 Amp System

•3-9 Amps - 9 Amp System

NOTE: The amperage produced depends on the battery voltage. If the battery is below 11 Volts, the output reading would be 5 or 9 Amps, depending upon the alternator system being tested. The amperage will be less at maximum battery voltage.

8.If NO or LOW output is found, be sure that the regulator-rectifier is grounded properly and all connections are clean and secure. If there is still NO or LOW output, replace the regulator-rectifier.

10 & 16 Amp DC Regulated Alternator

The 10 & 16 Amp regulated alternator system provides AC current through two YELLOW output leads to the regulator-rectifier. The regulator-rectifier converts the AC current to DC and regulates current to the battery. The charging rate varies with engine RPM and temperature.

The stator and regulator-rectifier are the same for the 10 and 16 Amp systems. The system output is determined by the flywheel magnet size.

Test Alternator Output

1.Temporarily disconnect stator wire harness from the regulator-rectifier.

2.Insert RED test lead (A, Figure 28) into the V Ω receptacle in the meter.

3.Insert BLACK test lead (B) into COM

receptacle. 2

4.Rotate selector to AC Volts position.

5.Insert RED (A) and BLACK (B) test lead probes into output terminals (D & E) in YELLOW connector (C). (Test clip leads may be attached to either terminal).

6.With the engine running at 3600 rpm, the output should be no less than:

•20 volts - 10 Amp System

•30 volts - 16 Amp System

7.If No or Low output is found, check for bare wires or other defects. If wiring defects are not found, replace the stator.

Test Regulator - Rectifier

NOTE: The regulator-rectifier will not function unless it is grounded to engine. Make sure the regulator-rectifier is securely mounted to the engine. When testing regulator-rectifier amperage output, a 12 Volt battery with a minimum charge of 5 Volts is required. There will be no output if battery voltage is below 5 Volts.
