- Checkthevoltagewhenthe
powerison.
► UNIVERSALMOTOR ChecktheResistanceofNos.1 and4ofthewirepinontheside
oftheTACHOSENSOR.
- Resistance:Approximately
40to45Ω(Normal)
► THREEPHASEMOTOR MeasuretheResistanceofNos. 2and3ofthewirepinonthe
sideoftheHALLSENSOR. - Therevolutionofthedrum
