Does anybody here know the size/thread of the battery bolts? What I am looking at is the smaller of the two, bronze color, closer to the center of the battery. My plan is to use an additional matching nut on each stud to connect wiring for a radio transceiver that draws less than 9A of current. I did a similar setup on the 2009 WK, and it worked; the WK2 appears to have smaller studs.
I tried a 7x10 nut and it was slightly too large, and a 6 mm nut was too small or would not thread over the stud... maybe the end of the stud has a "boogered" thread to keep the nut from being easily loosened. The online Mopar parts site shows a M6x1.00.
An alternative would be to use the larger stud (and corresponding "ring" terminals), but I prefer to no disturb any more stuff than necessary.
