We have an ROV that has a MINI FSESC4.20 ESC on it . it was accidently connected with the wrong polarity and now doesnt appear to work. so we purchased a new ESC same one and need to configure if for a single BRUSHED motor. is there a way we could connect the old ESC and get the way it was configured because we werent the people that originally set it up? If not then we are looking for some info on how to set this up for this motor. Any help would be appreicated.
