I needed to wire it into the phone itself as there is no plug at all.

Also the yellow is not necessary. Red-Red, Green-Green is all you need.

You might have one more problem. Back in the day some lines were "Party Lines," meaning several customers received ringing voltage whenever someone got a call. The way you knew it was for you instead of your neighbor was the type of ring. Hince the ringer on your old phone might not ring with todays standard ringing voltage -82 volts. All the old phones have adjustable ringers by twisting the bell inside. Try That if getting a loud ring. If that doesn't work, the ringer might need replacing.

You actually only need the red and green wire, the yellow and black were used as either a source of electrical power for a light, or running a second phone line

You should have used macro mode for the pictures.
But it sounds like a strange idea...
This is like the 3rd (I think) Instructable you posted today, nice job!

I happen to be working on an Instructable at the moment. :-)

You know, it would be one thing if they were six quality instructables, but its completely different when they're of such low quality and completely pointless. You're really just spamming. I think you should spend a lot more time refining your instructables. this one actually isn't too bad an idea, but its very poorly executed. It's really hard to understand what to do since you never give the name of any of the parts, or explain where to find a particular component on the phone. I'm talking specifically about steps 2 and 3. Where in the world did those parts come from? What is that part you're connecting wires to in step 2? You really ought to explain these things better. Oh, and by the way, its called a rotary phone. "Dial-up" refers to the modems used to connect to the internet before cable and DSL. It was called such because it connected by the phone lines.

in steps2 and 3, they dont sell those parts, i got the phone at my grandfather's house and those are the male & female ends of the old phone jacks. i cant stress this enough, IF ANYONE HAS ANY QUESTIONS OR PROBLEMS, JUST ASK ME IN A COMMENT.

I'm a little confused about steps 2 and 3, too. It looks like a 4-prong to modular adapter, but I don't understand where you got the female connector you put the modular cord into, unless it was some other kind of adapter at some point. (Hard wired to 4-prong, maybe?) Actually, I just realized I'm assuming that's a female 4-prong you're wiring the modular cord into there, so that might need clarification, too.

the 4 prong connectors are old and the male end comes with the phone. the female end you have to buy back in the 1930-40s when those phones where actually used, and the female end is the jack that you plug th ephone into way-back-when.
