Battery Flash now Low Voltage Error

Hi guys,

Just put the ev back together after a coupler refit - in neutral I was revving the motor at relatively low rpm when a 'flash' occurred at one of the positive terminals on the battery pack, this melted the terminal bolt (its a lithium pack and the voltage is reading normal at 110V) - after later inspection, the negative terminal was loose and perhaps caused this flash (arc)?

However I am now getting a low voltage error on the controller, main fuse looks fine (by visual inspection) - any thoughts?

Well I contacted Kelly and they replied quickly. They said that the low voltage error is only measured accross the B+and B/- terminals on the controller (which go to the motor). Unfortunately these are reading 110V which is normal. This tells me that something within the software / hardware is not resetting allowing the error to persist.
