20250404 Gremlins and Yard Work
Janet got to work picking up a lot of pine, palm and other yard litter, as well as weeding the front yard and driveway. The organic recycling bin had just been emptied before we set up the RV in the driveway, and Janet managed to fill an entire 52gal bin with debris she had cleaned up. She also noticed that Eileen’s boys were working on some sort of electrical project in the kitchen. Since Ben has had experience with wiring in our own house projects and remodels, he went to investigate.
Eileen had several items that were needing to get fixed. The first was that several undercounted lights were out. Her boys had disassembled one of the fixtures and they were puzzling over why it wasn’t working. They were trying to upgrade by replacing the small fluorescent tubes with LEDs, but couldn’t figure out why one wasn’t turning on. Ben determined the problem was a worn-out starter.
There was also a GFCI receptacle on one wall that was dead, and half the outlets around the kitchen were also not working. After pulling the GFCI partially out of the wall to check with a voltmeter, the circuit supplying it was not energized.
Eileen’s house is quite old, with part of the electrical system dating to the 1960s. The service panels are situated outside the house with one from the 1960's and a newer one dating to the 1980's. Unfortunately, none of the circuits on the older panel were labeled, and on a newer panel on an addition to the back of the house, only a handful of circuits were labeled, with more than half of the label missing altogether. So Ben sent the boys to Home Depot to buy replacement fluorescent starters matching the ones removed from the undercounted fixtures, a replacement GFCI outlet since these often do wear out and fail, and an inductive circuit tracer to find the faulty circuit.
We then had to test each outlet in the house and find the circuit on the circuit breaker panels to map out what was wired to what circuits. Unfortunately, because the circuit tracer can only feed signal back to the breakers on energized circuits, the tester couldn’t tell which circuit was feeding the dead GFCI. That was a lot of work with Eileen and Coby inside the house and Ben and Brevan outside at the breaker panels communicating by phone. Once the mapping was done, we treated ourselves to lunch at In-N-Out Burgers.
Even after mapping out all the outlets in the house, there were inexplicably dozens of circuits that didn’t correlate with any outlets. Now some are likely directly wired appliances like the ovens, but that still left at least a dozen suspect circuits. Direct inspection revealed a 30A 240V breaker on the old panel that had failed and needed replacing, but was so old that you really couldn’t find a replacement on the internet, let alone Home Depot. Ben bypassed that circuit breaker (don’t tell L&I!) just to see if either side of that circuit fed the dead GFCI, and neither did, so that breaker and its wires were left as found originally.
Then testing the output of each breaker directly with a VOM revealed one half of a double breaker on the new panel that was not energized, even though on its exterior, it appeared normal and not tripped. But after toggling the switch, it would not reset and was clearly broken. That was a real surprise because in mapping out all the other circuits in the house, all of the outlets in the front part of the house were mapped to the old panel, and none to the new panel. When Ben temporarily bypassed that bad breaker, the GFCI still was not energized. This was baffling.
Ben then pulled the GFCI completely out of the wall and discovered that the wires had been reversed such that the line inputs had been fed into the GFCI’s downstream posts instead of to the line in posts. This would explain the absence of voltage with the breaker bypassed. So Ben corrected this and restored the circuit to life by bypassing the bad breaker half by tying into an adjacent breaker that wasn’t assigned to anything on the residual label on the panel or anything we found testing all the outlets in the house. It’s possible it’s connected to something like a dishwasher or garbage disposal, which would be wired directly, but as a temporary fix until a replacement for the failed double circuit breaker could be found, it was safe.
We are steadily whittling down our Costco rotisserie chicken and made ziti arrabbiata with green beans for dinner. There are leftovers that will be another meal, and one chicken breast left, which will most likely end up as sandwiches.
We are planning on getting together tomorrow with Ben’s brother Dave, who lives nearby, to go for a hike somewhere, and then get everyone together for dinner at a favorite Chinese restaurant in the area, Chef Chu’s, which Ben first encountered during an engineering internship with Hewlett Packard during his college years.
