At 7:38 am the hoist would not reset on the remote estop, the crew reinstalled the jumper & still could not reset the hoist. A faulted estop contact block was found during troubleshooting, a loose wire and a pinched wire on the PA1 control desk. There were no miners in the shaft during this incident. The hoist was restarted, tested, and returned to full service at 9:58 am.
