TEST PROCEDURE

1.Turn engine off.

2.Using the 3/8" wrench, remove the left rear case cover.

3.Locate the engine alternator. See Figure F.24.

4.Start the engine and run it at high idle (1900 RPM).

5.Set the voltmeter for DC volts and measure the DC volts at lead #239 to engine ground. See the Wiring Diagram. Normal is 13.2 to 14.5VDC.

6.Set the voltmeter for DC volts and measure the DC volts at lead #238 to engine ground. See the Wiring Diagram. Normal is 13.2 to 14.5VDC.

7.Set the voltmeter for DC volts and measure the DC volts at lead #281 to engine ground. See the Wiring Diagram. Normal is 13.2 to 14.5 VDC.

NOTE: Lead #281 carries the flashing voltage for the engine alternator. Battery voltage should be present whenever the engine is running. See the Wiring Diagram.

8.If the correct flashing voltage is present and the charging output voltage is low or missing, the engine alternator may be faulty.

9.Stop the engine and check the alternator V- belt for proper tension. See the engine operation manual.

10.Replace the left rear case cover.
