[Johnson] AC Circuit Wiring Question

Not necessarily understanding everything I know, I have a question.  My 
Invader 2000 is wired like most other rigs of the 1960's era.  The 
neutral of the 240V AC is grounded to the chassis and 120V for the fans, 
etc are taken from one side of the line.  I have a 2KVA toroidal medical 
isolation transformer.  It can wired for either 1:1 or 2:1.  Would the 
use of this transformer eliminate the risk of a hot chassis if anything 
should go wrong?
