How old is the ozone generator?
Voltage?
I have the Gecko in.xe system in our Columbia; the new plasma gap generator had a 4' cord with no connector, though it came with a molex housing. I cut off the original cord from the CD generator & spliced it onto the new one. Original cord wires were black/white/green, new cord was the European style - brown/blue/green w/ yellow tracer. Brown/black is hot, white/blue is neutral, green/greenYellow is ground.
CD generators last 1-3 years depending on their usage model - the plasma gap is supposed to last 7 to ten... so I'm told.
