I have a Malibu ml200rt power pack that is 3 years old and has worked fine. It is connected to 10 landscape lights each with a 12 volt 20 watt bulb. The lights stopped turning on. The timer is working and going around but the lights will not go on. I have replaced 7 of the 10 light bulbs. Is there a way to fix this without replacing it? It's only 3 years old.

The EJ500C is designed only for standard incandescent lights, not chandelier bulbs, CFLs, etc. Replace it with the ST01C, and you'll be fine. Intermatic may even exchange it for you if you if you complain to them.

Sounds like the timer may not be getting power.

Turn the circuit breaker that supplies the circuit OFF then ON, as sometimes it's hard to tell if a breaker has tripped by looking at it.

It's possible that the circuit is controlled by a switch that someone may have inadvertently turned OFF.

Also, it's very likely that the circuit is fed from a GFCI receptacle (the kind with the test and reset buttons that are usually found in kitchens and bathrooms) that may have tripped. Those receptacles can sometimes be found in very obscure places. Check outside receptacles too.

If anyone has been digging in the yard or flower beds it's possible that the cable may have been damaged.

The problem will more than likely be your transformer. To test you can go get a cheap voltage tester from home or hardware store it to the lowest alternating current voltage setting and put the leads across the output of the transformer. Anything less than 12V and your transformer is shot. Its not expensive for a new one either if you just want to swap it out rather than messing with a tester.

Testimonial: "great info - thanks!"

I'm thinking that a better brand is in order. Mine shorted out and started a fire. Luckily we had just returned from vacation and put it out with a hose.

You can buy cheap plug-in timer, set power pack to override and then plug power pack into cheap timer.
Otherwise there are no repair parts for power packs other than on-off trippers.
Power packs come with 5 year limited warranty, so you are within warranty period. Good job saving the date of purchase, you outshine with that detail.
