Note that the old and new battery covers are totally different. I beleive 
the old one had metal contacts, the new one doesn't (the 3 D cells used 
by the new Big Trak are fitted horizontally).

Is it hte layout of the contacts that is the problem? I am pretty srue 
the original Big Track had a +/-3V supply for the motors coming from the 
4D cells. In other words there were 2 contacts on the cover linking the 
cells in aprts. It should eb easy to see how they are wired inside the 
Big Trak (a google search will find a page telling you how to take it 
apart), anf thus deduce the layout of the contacts.
