4-4) CHECKING FUNCTIONAL MEMBERS

（1）STATOR

Measure the winding wire resistance. Check the resistance of the wires that comes out from the stator using a tester, referring to the following table.

NOTE: When measuring according the numerical value shown in the chart, tolerance should be considered because the inaccuracy of the tester. If an accurate value is needed, measure by electric resistance using an Ohm-meter.

While doing this, use caution to avoid contact resistance.
