Scotty,

The most common cause for that behavior is a problem with T1 - leads not 
adequately stripped and tinned, leads not in the correct holes, the 
toroid wound in the wrong direction (it must be *exactly* like the 
figure in the manual), inadequate soldering.

One other (but less common) cause is for there to be a capacitor or 
inductor that is being left in the circuit.  The normal cause of that is 
missing a solder connection to one of the relays or the firmware IC.
