OSIM uSqueez foot massager sparking how to?
OSIM uSqueez permanently dead. Dismantled unit found mother board 2A fuse blown. Check everything OK on mother board and replace fuse. Power on unit led under stop button light up. Pressed vibrator button works perfect. Pressed massage button strong sparking sound and saw fire in one to two second followed by blown fuse.
1. Measure the motor terminal resistance -> 0 ~ 5 ohms. Or it should should have some high resistance approximately 10 ~ 50 ohms.
2. Measure BR-B3D thermal protector which was in series with the black wire -> 0 ~ 5 ohms.
Any idea which one is faulty part?
1. Think the thermal fuse is OK.
2. If the motor short, shall I do rewinding for rotor? Can't found this motor locally and if buy direct from OSIM too expensive!
Any idea measure rotor coil?
