My wife's 2010 journey base 4 cylinder has a problem with the starter positive terminal. The wire gets loose every now and then and leaves her car unable to start unless she wiggles the wire. I've tightened it up before but I forgot what size socket to use. Anybody know? Also is there an easy better way of tightening it besides laying on my back barely able to get the wrench on and only able to get one click at a time? Would be nice if I can actually get my hand on it to put a better washer on so it doesn't loosen again.
Thanks.
