Question about Hardware & Accessories

I replaced an old Malibu 300 watt powerpack with a new digital 300 watt Malibu power pack and when I turn it on it runs for about a miniut and then shuts down. I have 15 11watt light on it, the same as the old one. Any suggestions on why it shuts down? Thanks

300 watt power pack should have 300 watt load.
You have 165 watt load.

Problem might be the photo eye.
http://waterheatertimer.org/images/Malibu-8100-9045-01-large.jpg
Rotate manual dial to ON position and see if lights turn ON.
Keep in mind the digital power pack has photoeye that is light sensitive, and must be exposed to dark light to activate.
For timed functions. Rotate manual dial until it points at timer. Press clock set function button, and use up-down buttons to set current time. Press timer ON button, and then use up-down to set ON timer. Then press timer OFF button , and use arrow keys to set OFF time.

This product has 1 year limited warranty, contrast with old-type analog power pack with 5-year warranty.
Malibu does not even post a manual on their site, which might have troubleshoot section to illuminate why your system has problem,

SOURCE: Malibu ML200RT low voltage power pack is not working

First check to make sure that you do not have more watts pulling than is recommended. If this is ok then pull both the red and black plastic pin from the timer and replace them then try. If neither of these solutions work you may have a problem at power source.

SOURCE: I currently have a 600 watt power pack w/timer on

20A circuit x 80% service factor =16amps continuous. 16amps x 120V = 1920 wats. Your total would be only 900 watts. I have assumed that since you have a 20A ground fault breaker that you have #12 ga copper conductors. If you had a considerable distance the 16 amps continuous would drop due to voltage drop and so the total wattage would also, but you're way below these levels.

My power went off at my house. After it came by on how do I reset the transformer to come on automatically?

SOURCE: My Malibu 200 Watt Power

There is no fuse and no repair parts

I've been all over the Malibulights.com website looking for anything that might help the large number of people with Malibu questions. The website has very little information and no parts and the site offers no help except the following:

1) Malibu gets the customer money, and other people troubleshoot for their customers
2) When buying a power pack, the total bulb wattage on the line has to match the power pack wattage
10 - 20 watt bulbs = 200 Watt power pack
15 -20 watt bulbs = 300 Watt power pack
http://www.malibulights.com/guides_support/low_voltage_planning_guide/select_your_power_pack.aspx
If your power pack is oversized, it will burn out the bulbs and burn out the power pack

3) A power pack makes a humming noise when it has power >>> check your power source if power pack won't work >>> no other troubleshooting is offered
4) Replace burned out bulbs ASAP or the power pack burns out the other bulbs
5) Unplug power pack when working on bulbs [otherwise, the power pack burns out which is why people write fixya asking why their power pack won't work after replacing all their bulbs]
6) Nowhere on the Malibu site does it offer-or-explain burned out power packs or power packs that don't work, but they show plenty of new products for you to buy.

I had a Malibu ML150 power pack that quit, I need to attack a malibu 300 to the light wires. One is push one connection, the new one has screw clips. Do I cut the old push on connectors off?


Cut em off. Attach wires to A and B terminals on ML300.
Do not plug in power pack until all lights are wired.
Read the product manual.

Power pack doesnt work and is under warranty how do I get a new power pack?


'Harry' wrote me Nov 2010 and said his power pack has 5 year warranty and quit after 4 years.
He said he was 'in negotiations' with Malibulights.com
http://malibulights.com/home.aspx
http://malibulights.com/customer_service.aspx

I asked him to let me know what happens, but no report yet.
Same for you please: Add a comment and let me know what Malibu says so information is available for all Malibu owners and fixya supporters.

'Harry' also gave me a tip.
He said Malibu timer stopped working on his power pack, so he bought ordinary plug-in timer, and set Malibu override to ON, and plugged power pack into timer.

While researching Malibu problems, I assembled some power pack tips.
The reason I add these tips now, before your power pack needs replacement is some fella wrote-in.
He bought 500 Watt power pack to replace 300 Watt > thinking bigger was better.
Power pack burned out. Here's why:
1) Match wattage of bulbs with wattage of power pack
-15 each X 20 watt bulbs = 300 watts, so install 300Watt power pack
2) Installing a 500W power pack on 300W of bulbs will burn out bulbs and power pack.
3) Replace bulbs as soon as they burn out or other bulbs will burn out and power pack will burn out.
4) When working on bulbs, unplug power pack or it may burn out.

My 600 watt 12 volt transformer timer for out door lighting does not keep time properly. HOw do I get and install a new timer?


1) Amazon sells 600Watt power pack:
http://www.amazon.com/Malibu-8100-9600-01-Voltage-Power-Transformer/sim/B002ZRPM4A/2

2) I bought new 300Watt Malibu power pack at Home Depot about 2 months ago.
Near the lighting section.
My new power pack has electronic time clock, so no more 'slow clock.'
I think Home Depot had 600Watt.
Lowes carries different brand.

3) Manuals for power packs at Malibu lights.com
http://www.malibulights.com/customer_service/owners_manuals.aspx

4) Tips for buying and taking care of power pack:
-Match up wattage of bulbs with wattage of power pack
-15 each X 20 watt bulbs = 300 watts, so install 300Watt power pack
-Installing a 500W power pack on 300W of bulbs will burn out bulbs and power pack.
-Replace bulbs as soon as they burn out or other bulbs will burn out and power pack will burn out.
-When working on bulbs, unplug power pack or it may burn out.
http://www.malibulights.com/guides_support/low_voltage_planning_guide/select_your_power_pack

5) How to install power pack.
Before unplugging old power pack, check which bulbs are not working.
Replace bulbs using phillips screwdriver.
Unplug power pack.
Notice how wires are connected to power pack, write down terminal connections.
Some power packs have three terminals ... extra terminal is for additional photoelectric eye.
Use pliers or screwdriver to disconnect wires.
New power pack has has same terminals.
Plug in power pack.
Read instruction manual before connecting wires.
Save instruction manual because a few years that manual won't be around as products change.

My timer is running and I have swapped the black and red pins to turn on and off the lights but the lights do not come on? Were do I find the model number?


My model number is on a sticker inside the door.
I have the 300 watt, and it matches the total wattage of my bulbs.
A lot of people ask for replacement Malibu tripper pins on Fixya, so your tripper pins might be worn down. I cannot find Malibu trippers, even on e-bay. And the new timer clocks are electronic.
Check your circuit breaker to see if unit is getting electricity, including GFCIs in bathroom.
Plug hair dryer in same plug as Malibu to see if there is power
Brush a wire across the screw terminals to see if there is any spark going to bulbs.
It's unlikely that all the bubs failed at once, but if power pack shows spark on the terminals, the bulbs should be getting electricity.
If a couple bulbs burned out, the power pack can burn out the others.
Unplug power pack until you get bulbs replaced.

Unfortunately if the power pack stops operating, it is broken.

Apparently the motor is working but the timer is not running


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.

Malibu manuals are located on this page
Normal 0 false false false MicrosoftInternetExplorer4 http://www.malibulights.com/customer_service/owners_manuals.aspx

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

I need instructions for setting the timer


Malibu product manuals
http://www.malibulights.com/customer_service/owners_manuals.aspx

Manual for 300 Watt power pack
http://malibulights.com/docs/pdf/8100-9300-01.pdf
Read cautions

Tips
300 Watt power pack requires sum of bulbs to equal 300 Watts
If you use 10 - 20 watt bulbs that is only 200 Watts so you need 200 Watt power pack

Replace burnt out bulbs immediately or other bulbs will burn out and shorten life of power pack
When working on bulbs, unplug power pack so it does not shorten life of power pack

Set Malibu Timer:
Red trippers are ON
Black trippers are OFF
Place trippers on dial at ON OFF times/ AM and PM

Set current time of day:
Plug in power pack
Trippers are installed
Rotate dial counter-clockwise to current time, say 9 am
Rotate dial 2 more revolutions and then return to current time
That's it

Getting sticky, losing time as a result. No longer dependable for super time keeping as before. Is any lube, etc possible?


Power packs wear out

Usually people have old power pack and then remove all the bulbs while replacing and doing maintenance, and the old power pack burns up because it has no load. Unplug power pack when replacing all the bulbs, and keep burned-out bulbs replaced

In your case, the plastic gears have gotten dirty over time. Gears are probably worn. Un-plug power pack and spray WD-40 in and around plastic dial. Turn dial to see if it gets better.

Power pack should match total wattage of bulbs

10 - 20 watt bubs = 200 Watt power pack

10 - 15 watt bulbs = 300 Watt power pack

Timer will not tirun on the lights, it stops when it gets to the time to turn on.


Malibu home page
Malibu manuals

Try the manual override >>> un-plug power pack and try loosening manual override with WD-40

It sounds like the clock motor is unable to push the manual override
Don't continue to run power pack or the clock motor will burn up or break a plastic gear

If manual override will not work, or clock will not trip on lights, you need a new power pack
Power pack size chart and wire length

Be sure to buy same wattage power pack as you have
The 300 Watt unit is made for 15 - 20watt bulbs (15 x 20 = 300)
If you buy 600 Watt power pack and hook it up to 10 - 20 watt bulbs, it will burn out the bulbs
Manual also says to replace burned out bulbs ASAP or other bulbs will burn out.
