The following is a list of instructions for installing a 6055 Spindle Drive with the A20B-1001-0120 Spindle Drive PCB:

Instructions:

1. Make sure the jumpers on the new spindle PCB match the jumpers on your old spindle PCB.
2. Remove the software chips from the old spindle PCB and install them onto the new spindle PCB.
3. If possible, remove the NVRAM chip from the old spindle PCB and install it onto the new spindle PCB. This way you will not have to reprogram the chip as the new spindle will have the same instructions as the previous one.
4. If possible, remove the DAC chip from the old spindle PCB and install is onto the new PCB. There may not be a DAC chip on your previous board and if that is the case do not worry about it. However if the old board does have the chip, failure to install it correctly into the new board will cause issues.
5. Make sure to set the 200/230 voltage switch to the same setting it is on the old board. This switch also may not be on all drives.

It is very important to follow the manual and make sure that the chips and cards you are moving around are installed correctly. For instance, if you were to incorrectly install the software chips, not only would the display not show anything, you are leaving open the possibilities for a short and causing yourself even more trouble.
