nope totally understood what u meant
, maybe i should be a bit more clear, in this case the yellow/green wire should be null coz @ the other end of the outlet there is only 2 connection that is used to power up the eqt, 1 is the outer layer & the other 1 is inside the jack, by right there r only 2 wires & that is must be +(brown) & -(blue), blue is still intact & it's solded to the wing, only @ the center the wire had snap off & left it's mark, the -ve side of led is already solded 2 the other wing, left the earth wire unpresidented. so the main concern is wether we left it out or place it wit -ve led, so the application of AC trip to this is, if we connect the earth wire to the wing, instead of the current from +ve to eqt to -ve, it will directly goes from +ve to earth without entering the eqt, wait to think of it i'm positively sure that the earth wire are not connected @ the jack, they just use the 3core wire (electrician terms for these type of wires) because of the material & thickness of the cable pvc insulation. rest my case, in any case buy new one la but make sure the polarity is correct but i think they r all the same la standardized
