I had a punch down at one point, but I honestly cannot say what happened to it. I just use a small screwdriver, but the wires always are firmly "punched" down.

t g 10, I get to jump on you 1st! Take it from one oldster, NO SCREWDRIVER does a RELIABLE, CORRECT, punch down. Break down and buy another punch-down tool.

 No self-respecting "telecom guy" would ever punch down with a screwdriver! Heck, I've got BIX and Krone tools that I've only used one or twice - get the right tool for the job!

Hello all:
I know this is an old thread, but I wanted to give you all a very late update on this. I just fixed the key system on Monday-turns out, one of the flat key system fuses (the kind with the thin wire) had just corroded to nothing, so I replaced it with a piece of wire, and now my lamps and interrupter work fine.
Thank you Silversam for helping me pinpoint the voltage issue!

Well, I won't say I've never used a piece of wire to replace a burned out flat fuse- but I always replaced it with the right size fuse when I got one. One good tip - use a piece of thin solder to replace the fuse - until you get a real fuse to replace it with. The solder will melt away in a problem - hopefully before your power supply goes up in smoke.

I may have a replacement fuse for your KSU. What's the specification of your burned out fuse?

You can always use a standard Buss or Littlefuse pigtail fuse of the correct amperage. Just wrap the leads around the screws. If you replace them all you can dress them so it looks nice. I know it isn't authentic but as Sam says it beats burning something up.

"Up Nort" we call a thin wire a "Johnson" or "Anderson" bar named for the two Scandihovian inventors who taught it up over a couple dozen Grain Belts by golly.

The correct technical term is "no-blo".
If you do use a piece of wire, and the short circuit recurs, the full-wave bridge in the power unit will burn out. Then you have to go to Radio Shack, buy a new one, and replace it. That's what we did at New York Tel Co to avoid having to remove all the wires and replace the power unit with a new one. Much too much work. Easier just to break the rules and install a COTS unit.
You take the 18 Vac output off the front of the power unit and feed that into the bridge. One side of the output gets grounded, and the other side gets connected to the -24 Vdc screw.
