Ok I was wondering if anyone else has run into this problem. Close to 2 years ago I purchased the Showdown Troller 2.0 with the performance pack. I wanted to save on money by having a 12v battery instead of constantly using 6AA batteries. I tried to power on my unit about a month ago and it didn't turn on. The battery wasn't charged but now it is charged. Got the unit to turn on and after a few seconds it turned back off. Checked the fuse and the fuse is good. Checked the connections and they are good. When I use AA batteries I can get the unit to turn on. Could the problem be that I need a new wire harness?
