	of removing CN300, CN301, CN302
	and CN303 from P.C. board?
			YES
	The status that the resistance values
	between leads below are 12 to 22Ω.						NO
	Between	1	(Red lead)	and	2	(White lead)

	Between	2	(White lead) and		3	(Black lead)
	Between	3	(Black lead) and		1	(Red lead) of
	motor winding of connector (CN301, CN303)
			YES
