just got a set of new boards for the pj 24v to 240v, they have written on both boards 3kw . have i been duped or are they all the same. i think i read somewhere that they are all the same but there is to much to re-read. they have easy replaceable bolt on fet boards. but the only thing that is really different is a black lead coming out of the top of the control board, i would think that it bolts on to the negative terminal, can somebody confirm this.thanks.
