I want to use a 4amp Battery Tender maintainer when im gonna be away for awhile. Id like to use the ring terminals on the unit to connect to the car. I understand the positive jumper is a tab in the fusebox. Does anyone know which post is the positive post to be used with ring terminals? Also the Genesis dealer said not to use a battery maintainer on a Genesis but I don’t understand why. Attached picture shows me pointing to the positive jumper tab. Is the arrow pointing to the positive jumper post?
