I just bought this on ebay...
I had no idea what I was buying, again! I received it today, cleaned the layer of grime off it and straightened the bent dial. While I was putting the dial back on I noticed a rattling sound and removed the dial housing to find a sheet metal screw just laying in there. The dial housing was also screwed in to the Bakelite backing with three sheet metal screws. And there were no wires to the dial!
Does anyone know how the dial is wired in and/or have a wiring diagram? It appears to be a WE 1011.
Here is a copy of a test handset BSP from 1970, it contains earlier and later sets than yours.
BSP 100-120-101 i7 7003--Handsets (Dial and Test Sets);Description
Thanks!
My next (possibly dumb) question is how to take the top apart, where the dial is. Do I just remove those screws and carefully pry it? At first I thought it came in half but it looks sealed at the top and bottom. I wonder why the dial isn't wired in on this?
The 1011 test sets that have the small "pin" dial have three tiny machine screw/nut combinations at the very top of the rubber part. They are accessible in three little "tunnels" and can be loosened with a narrow screwdriver. The rubber is molded to hold the nuts stationary while using the screwdriver to loosen/tighten the screw head.
I posted pictures in this thread.
Is that the pin dial? It looks like a regular dial to me. ??
I wonder why the wiring would be just GONE for the dial?
Another Frankenphone?
These sets were not frankenphones The small dial was harder to use and some sets were upgraded? by adding a standard dial .The cup was almost the same as the C1-201? handset mounting.The wires were soldered inside the handle and might have been ripped out if someone was lazy and wanted the dial for another set
Good to know!
So do I just pry open the top part? I don't see any other way to access the inside.
Ok I pried it apart and there were wires!
Now the question is where do they go? I have the schematic and it shows colors but there's no color on the wires.
One wire goes to the transmitter, one to the clip-lead/black and the other to the clip-lead/red.
According to Fig. 13, one wire goes to the receiver. That wire connects to BK on the dial. Of the 2 wires that go to the plug, connect one of them to Y on the dial. Do you have dial tone? If not, substitute the other wire that goes to the p!ug.
The third wire goes to R on the dial. It shorts out the transmitter and receiver to suppress the clicks when dialing.
The circuit of these handset is very simple—you don't really need colors—and consists essentially of a single loop with the transmitter and receiver in series.
This loop also includes the dial pulsing contacts (BK and Y) and the capacitor/switch combo.
I think you have the 1011G which also shunts the line when dialing, so there is a third wire from the side of the line that is not already switched by the pulse contacts going to the R terminal on the dial.
Thanks unbeldi, poplar1 and the rest.
The way it's shaped, I thought the receiver was the transmitter. Then I put it to my head... literally.
I started to attach the wires and one just fell off! I re-soldered it to the square peg that holds the pin. Wired up the receiver to B, and the other two to Y and R. Plugged in and got nothing.
Switched the last two and got dial tone. The phone works and sounds great. And after some cleaning, it looks great too I think.
Thanks again.
I added a picture of something I'm REALLY glad I kept! It was given to me about 30 years ago and I just kept it "just in case."

That blue piece is interesting....I didn't know that existed...I learn new things on this forum every day!
The blue piece is a "banjo". You can make a poor man's banjo with a 4 prong-to-modular adapter. Tip and ring are on the wide spaced pins.

"Pourman's" banjo....got it!
Thanks!

Thanks Jim!
For the life of me, I still can't remember where it came from. But it's always been in the bottom of my wire/connector/junk drawer since I was young. And now I can get Denny's senior meals...
"The small dial was harder to use and some sets were upgraded? by adding a standard dial."
No, they were two different items. The pin dial was used in the field, so it wouldn't give you a perpetual bruise on the thigh from banging around on the tool belt. The one with the 6-type dial was used by the central office and PBX forces. That one came with the two-conductor plug/connector in the cord to allow the use of a bunch of different test lead ends.
Holding the set upside down by mistake is referred to as the "Eddie Albert Effect."

I love that one! :)
I've had a blast using this phone! It actually has great audio quality. I wonder what it felt like, though, to have this heavy contraption dangling off your belt on a daily basis? Of course I guess that was considered a "mini" phone for back then, right?
That Banjo thing, never seen it here, and this one: http://tinyurl.com/zwr6h5e (http://tinyurl.com/zwr6h5e) is close to $42 shipping inc to here.
So I made my own. just from parts I had.
I figured out that using it for telephone jacks (we use RJ45 here) it would be smart to connect the testwires at oposite sides to not short anything. I did put in both RJ45 and RJ11 (6P4C) to fit most jacks. For the older jacks, I have to use an adapter.
The little box has 8 female banana jacks located close to the edge of the box. Thestphones her does usually have banana plugs, but I have some with the angled crocodile clamps too, and both fits well.
The box is marked with color codes, and terminal numbers for the plugs, pair by pair. I am aware that other configurations of the pairs may be used. Usually we use the 2 center pairs, but when using the same RJ45 as LAN and telephone jack, the center pair should be preferred, and pair 4 brown and white could be used.

That's great. Thanks for posting. I actually thought about making one as well just using flat terminals soldered to a wire and then the RJ11. I like yours - looks like $42! :)
These can be bought on EBAY for as low as $25.65 with free shipping the US. Don't have to pay $42
I'm just going to make one myself. It looks quite easy. I'll spend the $25 on Starbucks coffee. :D
