the best and easiest way to track down a short is with a digital multimeter just check for continuity throughout the circuits.If you you cannot get your hands on a multimeter use a compass.It will detect and move left to right when there is a complete circuit and as soon as you hit the short the needle will be dead still. Fix the short and test.It would probably be alot cheaper than trying to track down a part with no certainty of it.Hope this helps
