We recovered the BF damper from the overflow of H3 primary coil.
- Opened the side hatch at the cross tube. Locked the BF body with the EQ stoppers.
- Disconnected the Dsub connector for the primary coils on the side plate of the BF. Checked the resistance of the coil side. The resistance between 3-8 pins (H3) was overflow.
- Found the lead cable from H3 coil was cut at 6~7cm from the pin side. Disconnected the coil from the Dsub connector side. Dismounted the coil bobbin.
- Repaired the cable. Cramped the new pin to the top of the lead cable. Connected the coil to the Dsub side. Checked the resistance. It was 9.2Ω. Mounted the coil bobbin.
- Connected the Dsub connector. Checked the signal on the medm. The H3 LVDT was working.
- Released the BF body. Closed the side hatch.
