Has anyone wired an MTH Firehouse (30-9102) to an AIU. I followed the instructions that came with the AIU and it does not work. It does work when I connect it convetionally to a transformer using the instructions that came with the firehouse. But when I wire it to the AIU using the wiring instructions that came with the AIU I only get lights but cannot operate the firehouse. Are the instructions wrong?
I have tried a few different wiring combinations but no results. Any suggestions? Any help would be appreciated.
