  5. MI Ground Fault • Ground fault isolated to the buss penetration from the MI60 south power supply to the tunnel • Wednesday evening it was reading ~10KΩ/Ground • Thursday Morning it was reading ~ 700KΩ/Ground. With the remainder of the buss connected (MI60-MI50) the lower buss was reading ~500KΩ/Ground, not good but OK to run • Buss penetrations covers were removed for inspection Thursday but nothing was found
