Weirdest thing has been happening to us and has not been easy to duplicate. Battery is fully charged and an operator is going in reverse, the battery meter all of a sudden goes to 0 and the machine coasts without any power to stop. Removing foot from deadman doesn't do anything at all. Driver reported 2 weeks ago and we shut down and powered back up, everything seemed to run normal. This morning it happened again and another operator backed into a pallet rack and injured himself. Has anyone seen this symptom before and have any ideas what it can be?
