DIAGNOSTIC TESTS

12.Connect the meter test leads across Stator lead 2 (Pin 6) at the C1 connector female side and frame ground. Be careful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

13.Connect the meter test leads across Stator lead 66 (Pin 9) at the C1 connector female side and frame ground. Be careful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

14.Connect the meter test leads across Stator leads Wire 11 and Stator lead 66A (Pin 4) at the C1 connector female side. Be careful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

15.Connect the meter test leads across Stator leads Wire 11 and Stator lead 2 (Pin 6) at the C1 connector female side. Be care- ful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

16.Connect the meter test leads across Stator leads Wire 11 and Stator lead 66 (Pin 9) at the C1 connector female side. Be care- ful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

17.Connect the meter test leads across Stator lead 66A (Pin 4) and Stator lead 2 (Pin 6) at the C1 connector female side. Be careful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

19.Connect the meter test leads across Stator lead 2 (Pin 6) and Stator lead 66 (Pin 9) at the C1 connector female side. Be care- ful not to damage the pin connectors with the test leads, use paper clips - do not force probes into connectors. See Figure 6-18. INFINITY should be read.

RESULTS:

If the stator fails any step replace it, for Steps 1-10 keep in mind resistance values may vary depending on ambient temperature and calibration of the meter used. If the stator passes all tests refer back to the flow chart.

TEST 10 - SENSING LEADS

PROCEDURE:

1.Set a VOM to measure resistance.

2.Disconnect Connector C1. See Page 17 for connector location.

3.Locate the male side of the connector located on the bottom of the control panel. See Figure 6-19. Connect one meter test lead to Pin 1 Wire 11S. It may be helpful to connect a small jumper lead to the individual pin. Connect the other meter test lead to Wire 11S at Terminal Block 2 (TB2) . See Page 17 for Terminal Block 2 location. Continuity should be measured.

4.Locate the male side of the connector located on the bottom of the control panel. See Figure 6-19. Connect one meter test lead to Pin 2 Wire 44S. It may be helpful to connect a small jumper lead to the individual pin. Connect the other meter test lead to Wire 44S at Terminal Block 2 (TB2). Continuity should be measured.

5.Unplug the six pin connector at the Voltage Regulator.

6.Connect the one meter test lead to Wire 11S at Terminal Block 2 (TB2). Connect the other meter test lead to Wire 11S at the six pin connector previously removed from the Voltage Regulator. See Figure 6-11. Be careful not to damage the pin connectors with the test leads. Continuity should be measured.

7.Connect the one meter test lead to Wire 44S at Terminal Block 2 (TB2). Connect the other meter test lead to Wire 44S at the six pin connector previously removed from the Voltage Regulator. See Figure 6-11. Be careful not to damage the pin connectors with the test leads. Continuity should be measured.

RESULTS:

1.If continuity was not measured in any of the steps repair or replace wire.

2.If all steps pass refer back to flow chart.
