About 6 years ago, we had our kitchen remodelled. We wanted some
undercounter lights included. The contractor proposed a low voltage set of lights. I said that I preferred 120 v since I hate humming transformers. He said OK and proceeded to do the job. Fast forward to last summer. We had a nearby lightning strike that took out a lot of stuff - DVRs, various plug-in power supplies, a Davis weather station, a garage door opener, etc. All of that was repaired but a few months later, I noticed the seldomly used undercounter lights didn't work. I started looking for the cause and realized they were low voltage halogens rather than 120v. So basically, there is a transformer somewhere in the kitchen with a blown fuse or winding. I have resigned myself to having to remove some drywall or tile to repair the problem, but I really don't want to use the trial and error method to find the transformer. The lights are near a number of 120 v circuits, but instead of tapping into those circuits, they tied into the circuit for the island. The island has a cooktop and some outlets for portable appliances. All that stuff works. I suppose it is even possible that the transformer is in the island and they ran 12 volt wire under the floor and up the wall to get to the undercounter lights. That wouldn't be how I would do it, but who knows. Between having hardwood floor, a tile backsplash, and granite countertops, the repair won't be easy, but step one is finding the transformer. Any ideas how to find it without tearing apart half the kitchen? Thanks, Pat |

If behind drywall, there should be an access panel, the operative word being "should". "Wands" are pretty available/cheap now, where you connect a signal to the end halogen, and follow it through a headset of sorts, listening for the strength of an audible signal. Really a handy thing to have for sleuthing, altho I forgot the generic term for this particular strategy. Phone guys used to use this all the time, to find the right wire in wired bundles.. Bummer about the lightning.... consider surge suppression (I started a thread some time ago on DIY surge suppression, lots of info there), or mebbe even an isolation transformer for the whole house -- proly not cheap, tho. So the contractor ig'd your wishes, eh? Can you find him to ask him where this thing might be? -- EA Thanks, Pat |

Thanks, Pat There are several possiblities. I would start by taking the light fittings out, you may well find there is an individual transformer behind each light. Failing that, you just gotta follow the wires back. Mirror and torch is handy to look in the holes where the lights are. They/it won't be far away. It might be better to abandon everything and start afresh. |

Failing that, you just gotta follow the wires back. Mirror and torch is handy to look in the holes where the lights are. They/it won't be far away. It might be better to abandon everything and start afresh. The lights themselves are mounted in a metal raceway on the surface of the cabinet bottoms. I am sure there are no individual transformers. The wires from the lights then run to a very shallow surface mounted box with a pushbutton switch in it. From there, the wires go into the wall through a very narrow slit above the backsplash tile / below the cabinets. Since my original post, I measured the resistance looking back into the transformer. It only measures a few tenths of an ohm. As first, that seemed "shorted" but I am guessing the secondary of a transformer would look that way as well. At least I can tell the transformer it isn't too far away. Pat |

Thanks, Pat I suppose it's unlikely, but the easiest thing to fix would be if all the bulbs were simultaneously fried, leaving the rest of the system intact. Did you verify that? Did you check the switch?- Hide quoted text - - Show quoted text - As an add-on. Do you have a voltmeter to see if there is any voltage coming out of the hidden transformer to the beginning of the bulb string. Any chance the bulbs are in series and a failure of any one bulb would take out all of them? |

To the other replies: Yes I have a multi-meter - 0 volts coming from the transformer. The bulbs are in parallel. The switch is good. Regarding the possibility of it being a switching power supply, I hadn't thought of that. It could be. If it is, the output filter cap must be shorted since it reads a few tenths of an ohm looking back into the wires from the switch. |

If you are referring to a toner and probe set that will run you about $80 to $100 dollars for the equipment AND you will need two 9v batteries to use it... You would have to disconnect the line voltage AC from the circuit by shutting off the breaker at your panel... You can then open up a fixture to attach the toner set and trace the wiring using the probe... Doubtful that you will be able to find one of these to rent, you can buy them at home depot or your local electrical supply house... Are you sure that the fixtures themselves don't have transformers in them ? ~~ Evan |

Thanks, Pat Now would be the time to upgrade to T8 flourescent, they are 75% more efficent, and since kitchens are usualy to hot any way your kitchen will be alot cooler. An incandesant only outputs 4-6% of energy used as visable light the rest of those watts is heat, I went T8 years ago. |

But had an idea before that; I have a shaver that when plugged in and but even running, makes clicks on a radio... my idea ..... although never used, was to hook up the shaver through an extension cord to the 'far end' of the dead circuit through some sort of temporary adapter. Then follow the clicking wiring back, using a battery radio. Suggestion anyway. Good luck. |

Wouldn't this be a good reason to get the 120 lights you wanted in the
begining ? Less hassel. Jerry http://community.webtv.net/awoodbutc...oodWorkingPage http://community.webtv.net/awoodbutcher/1974RuppCentair |

Wouldn't this be a good reason to get the 120 lights you wanted in the begining ? Less hassel. Might be too late for that. If all the wiring that is run is low voltage you can't just switch to 120V withour rewiring it, unless it was the correct wire and installed to code to support 120V. |

I'll look for one at HD or Lowe's. snip Sometimes they're called "fox and hounds" -- you hook up the fox and then use the hound to follow the wires; I think they're about 40 bucks at Lowe's. I purchased one at Lowe's for $40. Sperry brand - ET4220L "LAN tracker". It is a strange combination of really well thought out and poorly implemented. The supplied batteries were leaking in the package and the plastic parts don't fit well, but it works. You attach clip leads (or an RJ 11 or RJ 45 or coax connector) to the known end of the wire and then use the separate receiver to find the warbling signal. While I haven't found the transformer yet, I have a strong clue. As suggested by someone else, it may be in the space just above the cabinets. In this case, that places it in the attic above the kitchen. I definitely hear the signal up high on the wall. I can't bring myself to climb up there today since it is hot and dirty, but the next time I get the urge, I will see what I can find. To those who suggested replacing the lights with florescents, it would be just as difficult to install a new circuit as it is to find and repair this one. I am normally a person who uses energy saving ideas, but in this case, the fixtures have been used for no more than one hour total in the past six years since they were installed. It took us months to notice they didn't work. So, there is no energy savings to be had. I just hate to have them installed but non-operational. Pat |

Take a look.- Hide quoted text - - Show quoted text - Had a similar situation recently and then found a 'hidden' (although legally mounted and wired by a 'proper' electrician) fuse, behind a removable bottom drawer and a metal cover!. But had an idea before that; I have a shaver that when plugged in and but even running, makes clicks on a radio... my idea ..... although never used, was to hook up the shaver through an extension cord to the 'far end' of the dead circuit through some sort of temporary adapter. Then follow the clicking wiring back, using a battery radio. Suggestion anyway. Good luck. On a dead circuit like the one the OP has, the AM radio trick works with either a commercially available tone generator or the cheap route, using a door buzzer muffled somehow, towel or container, with one wire coming off it to feed the RF noise into the light string so it can be traced with the pocket AM radio. I've traced many a wire inside a wall using this method. Oh yea, the buzzer can be powered by either a battery or doorbell transformer. It will make a lot of RF noise regardless. TDD |

It isn't that hard to pull wires up a wall from below.

Thanks, Pat There are several possiblities. *I would start by taking the light fittings out, you may well find there is an individual transformer behind each light. Failing that, you just gotta follow the wires back. *Mirror and torch is handy to look in the holes where the lights are. They/it won't be far away. It might be better to abandon everything and start afresh. The lights themselves are mounted in a metal raceway on the surface of the cabinet bottoms. *I am sure there are no individual transformers. The wires from the lights then run to a very shallow surface mounted box with a pushbutton switch in it. *From there, the wires go into the wall through a very narrow slit above the backsplash tile / below the cabinets. *Since my original post, I measured the resistance looking back into the transformer. *It only measures a few tenths of an ohm.. As first, that seemed "shorted" but I am guessing the secondary of a transformer would look that way as well. Not to mention the load of all those low voltage bulbs in the circuit. What about that pushbutton? *Is it a circuit breaker? The bulbs were disconnected when I measured the resistance. *The pushbutton is not a circuit breaker. *Besides, no voltage is making it to the switch. Thanks for all the responses. *I'll report back what I eventually find. As promised, this is my report back about what I found: It took 10 months but I finally found time to to go up to the attic and found a blown transformer attached to the ceiling joists. *I replaced it and all is well. *The transformer was one of the newer switching types rather than a real 60 Hz transformer. *One of its internal components was literally blown off the circuit board by the lightning strike. *I think it was a resistor but it was hard to tell because the whole thing was potted in some sort of epoxy. *There was a chunk of epoxy loose in the box with half of the component embedded in it. *The other half was still on the circuit board.- Hide quoted text - - Show quoted text - thanks for the update its nice to know how things worked out |
