sounds like a dual voltage single phase,      high voltage    1 to line      4 to line   connect 2 and 3 and tape off,   low     should be     1 3  to line     2 4  to line,    if for some reason low does not work,     it would be  1 2 to line   and   3 4 to line,     most often it is the prior      neg or pos has no effect on single phase   only DC
