I have a trolley on a auto reversing track that i put up as part of a christmas display.  The trolley's power is cutting out, even w/ the controller on high.  The trolley will go a ways and as it's going i can see the head light  bright and dim as it chugs along.  The track is all tight, what else can i check?

Many Thanks!

i have a Christmas trolley setup on an auto reversing track.  Is there a way to increase the amount of time that it stops on each end of the track?  Also is there a way that i can stop the trolley in the middle of the track for a minute and have it continue on it's way?

many thanks,
