      Definitely fed 115VAC into the 18VDC trigger circuit if the original wires in the WC-1 weren't disconnected so the damage to the MM250 is now done.

      However, if the WC-1 has SPOT control a slightly different wiring rearrangement would have been required than what cruizer outlined but the necessary end result the same in that the original 115VAC power removed from the picture.

      I highly recommend you not attempt connecting the WC-1/SM-1 to the L-Tec and get the correct setup next time or you're likely to wind up with two dead machines.
