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!
Cleaning the wheels and the track is always a good place to start.
