I decided I needed the porch light working... when I removed it from the sidewall it had only the hot wire attached. It's a round snap-in fixture which takes a 12V small diameter push - n - turn bulb. On one side of the fixture there's a blob of solder where the ground used to be. The hot wire disappears into the foam, presumably someplace in there there's a broken off ground. Not enough room to go pearl-diving for it. I could see the edge of a rib though, and testing showed it to be a decent ground. So, I took my trusty Dremel with a stone mounted and shined the side of a Tinnerman clip and soldered a short wire to it. Other end got soldered to the lamp fixture. Pushed the clip onto the rib and skidded it around to make a decent connection, voila! I got a porch light.
I wouldn't try this trick for more than an amp or two, but if you need to ground something where you can't get a drill and tap or self-tap, it saves a lot of hassle.

On my left hand, nose - picking finger. Reach in and skid the clip as necessary.

Sounds like a good solution to me. What can go wrong? If it ever fails again all that will happen is the porch light will not work and you can go fix it a second time.

Johnny,
One of the little square boards with 9-16 LED's, glued inside that lense,
makes much more light, and draws so little current it can essentially burn
all the time (on shore power). :-)
