This is what I had understood the work would roughly look like:</div>

1. Hall techs do any testing required by Steve prior to any work, e.g. make sure nothing is shorted to the turret. </div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
2. Hall techs labels all the wires (basically putting 2 labels on each wire on each side of a cut)</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
3. Once labeled DSG would verify available slack to see if extensions are required for reconnection or not</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<div>4. Hall techs cuts the wires at the large flange in order to separate it from the turret</div>
<div>5. Hall techs do whatever mechanical work/cleaning/etc on the turret</div>
<div>6. In parallel with 5 DSG would fix any bent pins and any other cleanup/modifications on the wires/connectors</div>
<div>7. Once steps 5 & 6 are complete DSG would join the cut wires with solder splices and heat shrink.</div>
