All the various fixes to make the AC-12 better are a great help if we encounter similar problems. My fix is entirely different. When I ran my AC-12 for the first time I encountered a track problem on a long grade that I have ignored since building the layout. Up until the AC-12 arrived I got by, but knowing there was a potential problem spot. Well the AC-12 said H__L No! I'm not running through that curve climbing or descending a grade. So I went to work, removed 9' of track. re-aligned and re-worked the surface in spots. Changed scenery and made a big on-going mess for a few days. Now I am ready to re-lay the new track and rebuild the scenery all thanks to the beautiful AC-12.
