Question about Malibu ML200RTW - Low Voltage Power Pack -200 Watt - With Timer and Ground
The ballast inside is only rated for a predetermined quantity of lams using a set amount of wattage. To overload the system by adding lamps or increasing the wattage of the bulbs will cause a failure eventually. Also with these systems it is wise to replace bad bulbs quickly. Your problem is likely just a bad timer since the two components are isolated within the box.

According to Malibu website information, your power pack is correct size if lights come on.
The way to figure is this
10 bulbs x 18 watts each = 180 Watts
so 200 watt power pack is good
Does the manual override work?
Rotate the on-off button counterclockwise
If override does not turn lights on-and-off, then timer has a short
Does the center dial turn when power is on?
If the dial is not turning, then power pack is kaput, or time of day is not set
Did you reset the time of day?
How to set time of day:
Put your trippers in place
Red = ON
Black = OFF
Plug in power pack
Rotate arrow (colored blue in diagram) as follows
Turn dial clockwise to present time of day (diagram shows 9 o'clock)
Turn dial one or more full revolutions, then return to present time of day
If center dial is still not rotating after setting time of day, it's time for new $50-80 power pack, unless you put a $15 timer on that plug. A cheap timer might work ... keep it going for couple more years.
