I have two ovals connected using two Bachman crossovers.  I want to separate
the two and use two separate power supplies, one for each oval.  How can I
disconnect the transfer of current between the two ovals?  Can I simply snip
the red wires in the crossovers? If so, how many should be snipped?  There
are two pairs in each crossover.  Thanks for any info you can provide.  I am
very new as this but have a fair understanding of basic circuits.  This is a
DC only setup using Bachman Easy-Trac.
