THanks mvs sarma. Actually was looking for a book that just disects schematics. For instance at work I have a circuit board im working on and im stuck on it. 115Vac is getting rectified and the output coming out of the bridge rectifier is around 65Vdc on a good board. When i measure the bad board , the output is around 45Vdc.
THe problem is this...voltage coming out is going to different locations on different sheets and all of those areas are failing with 45Vdc but is there some kind of way we can have a short cut because it would take too long to measure each component where its failing on different sheets.
I will post the schematic.
