Last night I went to install a remote battery pack that I got off of my friend. It's a 4 battery pack that holds 3 and has a diode in the 4th battery spot. I hooked it up and after a few minutes I noticed the batteries were getting warm. All of the positives face down on the board so I installed the dowel for the positive going down and the negative going up which should be right.
Is there an issue installing remote battery packs on system 11 games or something I might have done wrong?
