MTH Z-750 transformer problems

Jeff B. HaertleinOGR Forum Member

I am getting a set ready for a friend's little boy and I have a used Z-750 transformer. I have put a couple of MTH Premier engines to test the loop of track, and once the diesel engines start up the horn wants to blow continuously and will not move the engine. Trying another engine the same thing happened, but all of a sudden the engine took off and basically no control of the throttle, then stopped and horn blows all the time. Any ideas? Would I need a complete Z-750 package or is it just the throttle control and not the power brick?
