TEST PROCEDURE – Exciter Winding Voltage Test

11.Turn the engine off.

12.Locate the exciter leads T1, T2 and T3. See Figure F.26.

13.Carefully pierce the insulation on leads T1, T2 and T3 for voltage measurements.

CAUTION

Make the smallest possible puncture away from any sheet metal parts. Reinsulate these punc- tures at the end of this test.

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

15.Using the voltmeter carefully check for 460

-550VAC from T1 to T2.

16.Using the voltmeter carefully check for 460

-550VAC from T2 to T3.

17.Using the voltmeter carefully check for 460

-550VAC from T3 to T1.

If the Exciter Winding Voltage Test is OK and any of the other voltage checks are low or missing, the stator may be faulty. Check for "shorted" or "grounded" windings in the stator.

If the exciter voltages are low or missing, the capacitors or associated leads may be faulty. Check for grounded or shorted windings. See the Wiring Diagram.

18.Replace the front shroud and all case covers that were removed. (See the Case Cover Removal Procedure.)
