I am using a 12vdc invertor to supply 240v ac to my vehicle-spark plug, plasma system, which requires that I have both a 240 vac earth (neutral) on the engine block and of course the standard 12vdc earth (neutral) . I need therefore to isolate the invertor from this lcommon earth? and wondered how I might be able to do this (maybe by using an isolating transformer?? but how would I attach it to the system? at the high voltage end or the low voltage and where would I put it and how would I connect it (ie wire it in) and what sort and type of transformer would it be? ) )) any help would be most gratefully recieved as I am about ready to switch it all on, both low and high ac and dc voltage but until I can be satisfied that the two earths won`t find a common path which they will at the moment I dare not without smoking it all??? ((
Regards and thanks in anticipation
