TEST PROCEDURE

14.Connect the test leads J50 and J51 to the stator winding under test. Close S1 and read the volt- ages at V1 and V2, then open S1 IMMEDIATELY. Damage can occur to the stator winding under test if S1 is left in the “on” position for too long. CAUTION: The 1 ohm resistor will also become hot very quickly and can burn to the touch. Leaving the circuit on for too long can also cause the winding to heat up causing errors in mea- surements.

15.Use the following equation to determine the winding resistance:

V2/V1 = winding resistance in ohms.

16.Disconnect J50 and J51 from the stator winding under test. Check the resistance of all the stator windings by repeating steps 13 & 14 and using Table F.3 below.

NOTE: The resistances in the above table are to be measured with the windings at an approxi- mate temperature of 25 degrees Celsius (room temp.). Measuring after the windings are heated up can cause errors in the above table.

17.If any of the continuity checks fail in steps 7 thru 16, then the stator is bad. Replace.

18.If the test is complete, reconnect the 3 bolted connections for the T1, T2, & T3 leads from the stator and exciter module, and capacitor leads. Make sure that the T1, T2, & T3 stator leads are matched to the T1, T2, & T3 leads from the exciter module respectively. Mismatching the leads will cause the “---” or “CRS” to be stuck on the display at power up, and no weld output. Cover each bolted connection with sleeving after reconnection. Replace Plug J2. Reinstall the left side engine and stator cover panels and the front shroud per the “Case Cover Removal” section.
