I have read and understand the sticky on DIY on here, but after reading several threads and seeing the you guys' friendly nature, I'm going to take a shot in the dark that maybe someone is willing to lend an ear. I just moved into a 12-year old place with a nice landscape lighting layout. Very few of the lights, unfortunately, are functional. But I'm sure they were awesome at one time or another -- I'm guessing, because it was a $2000 install even in 1997 (I was lucky enough to find the wiring layout and receipts in some of the documents left in the house). Here's my question. I've tested the transformer and it seems to be working without issue, outputting 12-13.5V, depending on whether the switch is on "low" or "high" (as a side note, didn't expect to see an output selection switch on a transformer, but maybe that's pretty normal -- anyhow). However, even with the transformer working, I yanked up the first light on the chain and apparently at least a few of the lights are only getting 6-8V (on a clean cut of copper - not a corroded contact). So here's my question: is that a normal, acceptable voltage drop? I'm guessing not. I checked some of the other lights and they are very similar in voltage. I don't know if I should expect the wire to be good after 12 years, although I don't see why not. It does appear to be the "good" stuff, it's labeled Kichler -- I don't know the gauge but I'd guess 12gauge just based on the insulation. I had hoped to use the existing buried wire from the pro install and just replace some lights to be back in business, but it's looking like I'm going to have to start from scratch Any thoughts? Thanks.
