Trouble-Shooting Circuits
You must do all of the following, not necessarily in the order given!
¨ 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
¨ Hove someone else check it against the circuit diagram
