Question about Malibu ML88TL 88Watt Low Voltage Power Pack with Timer

1 Answer

I thought my (88) low voltage power pack was worn out because it wouldn't advance to the the designated time and I had to click on by hand. I just replace it with a new one and still it won't advance...I even tried the one I use in the back yard, it won't work either. I have disconnected the tv, lighting, fans etc (in screened garage) in case it was too much draw on that recepticle.....I can hear that it is on but no clicking or advancing....So one last attempt, I used a heavy duty ext cord from an entirely different recepticle and still the same problem. Now I know the wiring to the lights was ok because I turned the original transformer off by hand this morning when it was daylight. This is certainly a mystery to me....Thank you for your feedback...E. Connell, Lakeland, Fla

Hi have an 88 cbx750 f2 the sprag in the slipper clutch is slipping, installed 2nd hand low mileage unit , better but still slipping above 6000rpm at times

Most of my friends with 88 slipper clutches spray paint their rims black, and it seems to help. One guy actually put new springs in his. Clutches slip because the friction material is worn out or the springs have lost their tension or their spacers. Put a washer on all the spring bolts and see if that helps, if it does, get new springs.

Flippers not functioning

be sure that the trippers you are using are for this specific model if you purchased them seperately.
if they are for your model then make sure they are fully seated so that they are engaging the switch. if you are using trippers you have had a long time the remove one go to your local store where you can buy the low voltage power pack. they should have additional trippers to go with your model examine the new trippers to make sure yours look the same and are not worn or broken. if all appears good then you may have a problem with the switch that is engaged by the trippers and the unit may need to be replaced.

I have the ML300RTW transformer. Just need to know about the trippers, one red and one black. Which one turns the system on and which one turns it off.

Here's how to check your power pack: Connect everything and set trippers randomly, and then manually rotate dial clockwise and watch when lights turn on-off, this will let you check if you have trippers set correctly.
As time passes, the dial rotates, and trippers push on-off lever that turns low-voltage lamps on-off.

If trippers no longer work, it's because trippers are worn down or the lever is worn out or the electrical contacts have burned. And the clock motors slow down and burn out.
There are no repair parts for low-voltage transformers. No trippers or timers.
"Harry" wrote to fixya with idea when timer no longer works: he bought cheap plug-in timer, set power pack to override, and then plugged power pack into cheap timer.

Since there are no repairs for low voltage transformers, I found tips that might save money:
The reason I add tips now, before power pack needs replacement is some fella wrote fixya.
He bought 500 Watt power pack to replace 300 Watt > thinking bigger was better.
Power pack burned out. Here's why:
a) Match wattage of bulbs with wattage of power pack
Lets say you have fifteen 20 watt bulbs = 300 watts, so install 300Watt power pack
b) Installing a 500W power pack on 300W of bulbs will burn out bulbs and power pack.
c) Replace bulbs as soon as they burn out or other bulbs will burn out and power pack will burn out.
d) When working on bulbs, unplug power pack or it may burn out.

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.

Having trouble setting timer o ML200RT

Set on-off times by setting trippers
-Insert trippers
-Red tripper is ON
-Black tripper is OFF
-New timer has 2 sets of trippers

Set time
-Plug-in & turn-on power pack
Turn dial clockwise to set time of day

Manual override:
Turn manual-on-off switch counterclockwise

-Power pack not turned on
-Plug does not have power > try hair dryer in plug to see if it turns on, check GFI breaker in bathroom, replace plug
-Manual-on-off is set to OFF > rotate to ON
-Outdoor lamp burned out > test with another lamp
-Important to replace burned out lamps promptly, or other lamps burn out quickly
-High household voltage will reduce life of timer
-Timer designed to last for many years under normal conditions

Why is my malibu 200 watts transformer not working, the timer will set off the lights but then not turn them off, then the next day they wont come on but when I rotate the dial they come on? Frank

Tripper might be worn down and not pushing switch.
Switch might be broken or worn down.
Improvise by setting timer to override and plug power into cheap plug-in timer.

Timer not working Malibu ML88T Power pack

there are multipul 12 timers on the market BUT if you use a 12 volt power pack designed for a car radio display or even a simple 12v 5 amp laptop power suply and a cheep outdoor timer or cheeper indoor timer and run wires inside you can add lights
remember theise lights are low voltage and if you change the bulbs out you can really strech out the amprage too
low amp led automotive bulbs are a great invention they draw mili amps and use 12 volts
i converted my noma moonrays to a laptop power supply and added 30 more to a single string so i curently have 50 lights on 1 power suply pulling aprox 4.5 amps out of a 5A power supply i used led bulbs and simple moma cord now i can light the whole back yard with 1 ps and it's really bright if i use the led headlamps mounted under the soffit on the house

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.
