I have never seen any case in which enough coupling occurred between 
insulated wires to run a motor -- except in transformers, where the 
coupling 
is designed in.  I can't imagine it being able to run the timer motor on 
an 
ET charger.  

BUT -- if the timer motor were wired in parallel with the transformer 
primary, I can see how having another switch in parallel with the timer 
switch could indeed cause the effect you mention.  Instead of paralleling 
the new controller with the timer switch, you might add a DPDT switch to 
select between the new controller and the old timer.
