Hi Chrissie: You've probably got this sorted by now but if not the 1st thing i'd do is to look at the PSU under an illuminated Magnifier just in case there are any solder slivers or accidentaly damaged print on the PSU. If that's not the problem it should'nt be too hard to trace the 24v line with a Meter or Scope & the Circuit Diagram.
