Additional instructions:
-Remocve the 4 screws and the controller will come right out
-Unplug all the connections and then reconnect the new one ( everything only plugs in one way )
-Be aware that there might be a slight spark from within the yellow connector on the battery when they reconnect it, however, it is safe. Since it is not an exposed arc, the connectors are designed for that.
