I have a 400w mh/hps ballast and I have it plugged in an extension cord with out the ground so I bought a converter and when i went to plug it back in it sparked and my mh light won't come back on... and there's power to the extension cord any ideas wat happened?
 
did you unplug it, add the converter & plug it back in?? a ballast needs 15 min or more to cool b4 relighting.
or try it again w/out the converter
