When wiring photo-eye to power pack, the wiring is changed from what shows in power pack manual:
Open following links for power pack resources:

http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

Photo-eye manual shows correct wiring:
Photo-eye: Solid-black-wire to A, red-wire to C, middle-wire to B.
Lights: wires to lights are moved to terminals B and C

The Malibu ML200RT is intended to operate _12_ volt AC (low voltage) lighting _only_.
Assuming your fountain pump is 120 volts, the needed set up would be to supply 120 volt circuit to an Intermatic T101 timer (or similar timer), then connect a GFCI receptacle to the load side of the timer. You could then plug your fountain pump into the now timer controlled GFCI receptacle.
You can use the same 120 volt circuit that supplies the ML200RT transformer.

working with those outdoors transformer I have ran into couple would short the unit out by installing it wrong or exposing to lots of waters/moister. Again, it could also be a factory fault unit, some products will only last only few days before it blow out. It happen and most of those unit have 5 years warranty on them. I would take it back and get another and if it happens again than you may not installing it correctly or installing too close exposing to lots of moister and may short the unit out. I don't recommend trying to fix it still having warranty on them, get a replacement and start over. good luck and i hope that help some

If you have a meter you can test for 12 volts AC on the output of the transformer. They go to terminals
A & B
