1) Problem could be transformer voltage and/or length-and-diameter of wire.

2) Open following link for power pack resources including links to manuals, tips, trippers, instructions, and troubleshoot:
http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

3) Unclear what is meant by 1st half and 2nd half of lights.
Do not connect transformers in parallel or series with each other.
Test across terminals A and B and see if it shows 12 Volts. If voltage is less, then power pack is not functioning correctly.
Power pack wattage must match total wattage of bulbs.
First bulb must be 10 feet away from transformer.

4) Use following chart for wire size:

5) Review resources above, and then add a comment for more help.

Since it is uncommon for a power supply to vary, it is more likely there is a variable drain on the system, such as a nick in the insulation, variably grounding depending on soil moisture.

I would suggest isolating most of the circuit, and only plugging in one light at first, and then adding more until you find a change.

The other way to do it would be with an inductive ammeter or audible pick up, and trace the circuit, detecting a drop in current or sound right after the drain.

These dang power packs don't have replacement parts. You can see if the manual override turns lights on and off. The power pack makes a humming noise. If the timer is not rotating, then try setting the current time.

If you buy another one, be sure to match up total wattage of bulbs to the power pack wattage.
For example 10 - 20 watt bulbs = 200 Watts >> you should buy 200 Watt power pack
15 - 20 watt bulbs = 300 Watt power pack
Oversized power pack will burn out the bulbs
Also if you let bulbs burn out, it will shorten life of power pack
Unplug the power pack when working on the bulbs

The power pack should make a humming sound when ON

1) Maybe power to the plug is off
Plug hair dryer into plug and see if it works
Check your GFCI resets in bathroom and kitchen
Check breaker in box

2) Maybe time of day needs to be set
Unplug power pack > plug back in > set on-off trippers
Rotate dial counterclockwise to present time
Then rotate dial two complete revolutions and return to present time

How to select power pack: # of lights and length of wire

You posted under Intermatic-malibu power packs.
Wattage of bulbs must match wattage of power pack or bulbs and power pack will burn out.

Your power pack might be damaged beyond repair.

To connect the Malibu LV814PR photo control to the Malibu ML200RT:

On the bottom of the power pack you should have 3 terminals: A, B, and C. The trick to understanding how the photo control is connected to the power pack is to understand that the "C" terminal on the power pack is a "dummy" terminal. It is _not_ connected to the transformer in _any_way. It serves the same basic purpose as a wire nut, it's just a connection point.

To avoid confusion following these instructions, disconnect your existing wires from the lights to the power pack. (they should already be under terminals A and B.

To connect the photo control:

1...Connect the outside solid black wire from the photo control to the "A" terminal on the power pack.

2...Connect the center wire from the photo control to the "B" terminal on the power pack.

3...Connect the red striped wire on the photo control to the "C" terminal on the power pack.

4...Now reconnect the lights, except this time connect one wire from the lights to the "B" terminal (along with the center wire from the photo control) and the other wire from the lights to the "C" terminal (along with the red striped wire from the photo control).

Alternatively, one could not even use the "C" terminal and just connect those 2 wires with a wire nut. Kinda messy, hence, the reason for the "C" terminal.

If you want to have the lights on from dusk to dawn, remove both the red and black trippers and turn the manual switch to ON.

If you want the lights to come on at dusk and OFF at, say, Midnight, put the black tripper at Midnight.

Enjoy your lights.

Guess is that the primary winding on the transformer (in the box) has a shorted winding. No fix. Replace the transformer.... and be sure that the load (total wattage of the lights being serviced) does on exceed 90 percent of the power pack capacity.
