to check a cap.....use an ohm meter, best is an old style analog, but digital will work. put the probles on each of the cap's terminals. Reverse the leads on the terminals. Everytime u reverse the leads the meter should jump from a high resistance reading and drop down to a low.
If meter reads a high resistance all time, the cap it shorted. If it gives no reading it is open.
Hope this helps and good luck....Bill
