A customer of mine calls to tell his lighting transformer isn't working. We service his irrigation and some other maintenance related things. I stop over I see the 15v tap is completely melted. Send the box to HADCO because they don't do warranty swaps like everyone else. They agree to warranty 4 weeks later. Go over today to install the new box and decide to do some quick calculations to see if the system is balanced correctly. I realize there are 13 lights on a 300w transformer. Each has 20w bulb. 260w. Pushing it but shouldn't be melting stuff. Can't figure out why there is only one 12/2 coming into the transformer with all these lights. Start digging around ( see attached ) Not one wire nut was a silicone all quick snap connects that were shorted out. Every strand of wire I stripped was turning black / blue inside. Lots of black tape everywhere. I pulled all the wire, rebalanced the whole thing and split some off to another transformer he has on the other side of the house with 80w on it. Go figure. While working on the transformer I noticed something out of the corner of my eye.. His rain sensor I have been looking for for 2 years now. Spring is here!
