I don't see your specific manual, but the operation might be similar to the ones shown here ... it could be that Malibu repeats the same instructions in different models

    25% of my downvotes are from disgruntled Malibu customers who have busted power packs. I don't bust power packs. But once their busted, there is no repair. There are no repair parts. There is no repair for a power pack that has electricity and doesn't work. Perhaps before downvoting the free answer, you could add a comment and ask how many hours I've looked for Malibu parts and solutions for folks with busted power packs. Ask how many of the manuals I read for the benefit of Malibu customers with busted power packs. Maybe the downvote should be aimed at Malibu and not the person providing free, accurate and truthful answers to disgruntled Malibu customers. Or pay for an answer at fixya, to check the absolute 100% guaranteed truthfulness of the answer provided for free.

    ML88 is Intermatic power pack, not Malibu.

The direct link to the manual is .

I hope this helps.

You did not say if these power packs are new or if they stopped working.
The humming sound says transformer is working, but terminals have to test 12Volts DC.
If power packs are older and were left plugged in when bulbs were not working, then power packs can go bad.
There are no replacement parts for power packs except trippers.
