¨   Carefully check circuit diagram – redraw it as a loop diagram

¨   Check circuit board connections – rebuild it on a different part of the board

¨   Check each element works as it is supposed to

¨   Break circuit up into smaller blocks and make sure each works as it is supposed to, and then connect the blocks

¨   Check that the equipment is working as it is supposed to

¨   Switch out circuit elements and equipment one at a time

¨   Completely rebuild circuit elsewhere
