How to set analog timer
Connect wires to Terminals A and BC is only used with ML series photo eye
Tighten screws very tignt against wire. For longest life of product, install first light 10' away from transformer. Read more tips section above.
600 and 900 watt transformers have 2 separate A-B-C terminals for 2 separate cables.
Terminal C. Not all ML series timers have terminal C. Terminal C is not used except for ML series photo eye.
Read about connecting photo eye, #6 below. Note for photo eye installation, wires to lights are moved from Terminals A and B, to terminals B and C. Read #6 below.
1) Power pack makes humming sound. Yes. All transformers hum. If power pack is not working: Check that outlet has electricity, use circuit analyzer to check outlet, check if GFCI outlet has tripped, check circuit breaker is not tripped, and that power pack unit makes audibe humming sound when working. Timer has not been under water or exposed to power surge. If timer has 120Volt electricity, and outlet polarity is correct, but power pack is not humming, then transformer has gone bad, and there is no repair. Bring extension cord from another outlet, and try timer on different outlet. You can try opening timer and see if a wire has come loose. Also read warranty information below.
Transformers are sometimes warm to touch, but never HOT. Transformer that is hot, is probably not functioning correctly. Read warranty information below.
2) Test outlet: Test outlet using cheap circuit analyzer from home center to check for polarity issues that can affect electral devices. See outlet polarity and circuit analyzer lower on page. Outlet must be wired correctly. See image of circuit analyzer
Check outlet with multimeter for 110-125Volts AC. Outlet must be 80% rated voltage. Undervoltage such as 88Volts can cause power pack not to perform as expected.
3) Test A-B terminal output voltage: You can see spark when wire is brushed across brass terminals A and B -or-Use multimeter and test across terminals A and B shows 12 volts and nothing less.
4) Observe bulbs: Check all bulbs are good, bulbs are not broken or under water, wire going to bulbs is not cut, wire is connected to terminals A and B, terminals are clean and wires are attached firmly. Some power packs have terminal C. Terminal C is not used except when installing ML series photo eye. Make sure only copper wire, and no insulation, is under the screw terminal clamping plate. See example image
5) Bulb wattage is important: Wattage of bulbs matches power pack. For example, if you have 15 each 20 watt bulbs, then use 300 Watt power pack. Mis-matched wattage can damage power pack. Replace burnt out bulbs immediately. Un-plug power pack each time working on bulbs. In the case of 600 watt power packs with two sets of A and B terminals, put 300 watts on each set of terminals.
6) ML Photo eye installation: If you have Intermatic power pack photo-eye then power pack has A B and C terminals.
Photo-eye wiring is following: solid black goes to A, red goes to C, and middle wire goes to B. Then wires to bulbs are moved to terminals B and C.
Disconnect photo eye to see if that is source of trouble. When using photo eye, change wire going to lights from terminals A and B to terminals B and C, when removing photo eye, move lights back to terminals A and B.

7) Check override: Manual override works, and turns lights on and off. Manual override is usually the knob that sticks up and is located above and to left of timer dial. Manual override rotates one direction only. Rotate manual override and lights should turn on and off. Override is temporary, and programming resumes at next tripper. To override permanently, remove trippers from dial.
8) Trippers: Check that trippers are not worn down. Both on-and-off trippers are present. Trippers are red and black. Trippers are pushed all the way down. If trippers are loose, worn, or are not pushed down fully, then they will not click the on-off lever. Use fingers and rotate timer dial clockwise to watch trippers click the on-off lever and watch lights turn on and off as trippers rotate around. If trippers do not turn lights on and off, then buy new trippers. See tripper ordering link below.
9) Dial must rotate: Check that dial rotates correctly and keeps good time. If dial is not rotating, or not keeping correct time, or dial stops at tripper, then clock motor is bad:** Remove trippers, set timer to override, and plug power pack into cheap timer that plugs into outlet. Some people report taking apart timer clock and cleaning gears. Some people report that gears are worn down.
10) Set current time: Reset timer dial to current time according to manual###. Manuals at Intermatic. To set dial-type timer, manually rotate dial clockwise for two complete revolutions and then line up current time with arrowhead located on inner dial.
11) Power outage: Timer must be reset after power outage. Power outage, power surge, and nearby lightning strike can cause power pack to suddenly stop working. Power surges can affect any electrical device.*** Unplug power pack if breaker trips or power turns off. Then wait until electricity is turned back on.
** People report taking apart timer, and cleaning gears and applying bit of white grease or vaseline to fix timer. Replacement PB912M10 timer module is not available. Read1 Read2 Read3
***Nobody reports they fixed low-voltage transformer once it stops functioning.
If lights still turn on, then plug power pack into another timer. For example an outdoor timer with photo-eye, or any plug-in timer. Example1 Example2 More examples
Whole house power surge is recommended today since many expensive electronics are not protected, such as timers, tankless water heaters, gas water heaters with blowers and electrionic controls, energy-smart electric water heater. Also recommend surge protection for co-ax.
3 possible repairs
1) Take apart timer and clean gears and apply white grease or vaseline, and timer function might restore if motor did not overheat and gears are good. Take photos for ez re-assembly.
2) If manual override can turn lights ON, then buy cheap plug-in timer, set power pack to override, and plug power pack into cheap timer. Example timers
3) If manual override can turn lights ON, and power pack has A-B-C terminals, you might operate lights by installing photo-eye.

|How to test and wire GFCI outlets and
Malibu power pack should be plugged into GFCI-protected outlet
Check if GFCI has tripped.
If power pack is tripping GFCI, then use extension cord to temporarily connect power pack to different outlet. If temporary connection works, then check and replace GFCI outlet.
If power pack does not work correctly with new connection, then power pack has gone bad. Check warranty information on this page.
