I didn't say that it is not CALLED "ground." I said that it has no earth reference, and therefore cannot "leak" to earth through wet tires. Go set a D cell on the wet sidewalk, with its positive button facing down, and no other connection to it. Tell me if it runs down.
The "ground" side (negative or positive) is called that as an easy way to differentiate it from "hot." It could just as easily be called "return."
(The British refer to it as "earth" but they call everything that is grounded "earth," so that's irrelevant.)

Sorry, again off topic....but....... Gee....Arthur, can you still set the cam on a reperforator? Ribbon feed vs. tape feed? Ratchet pin vs. wire? Ever use an optical reader on that TTY? Use burst? We had TTY set up for high speed UHF radio signal at the MidWest Relay....real fun. Yes, the good old days....aren't we glad they are gone?

I am constantly scolding my teenagers for walking around like Zombies, "texting." I call it the "cellular telegraph" and they look at me like the Luddite that I am. I'm sorry, but the telephone is a perfectly adequate way of communicating, I tell them, and my salary from the telephone industry has provided you all the goods and services that you need or want. Why have you regressed to a technique from the 1860's? I ask. Sheesh.

off topic, but on a Cisco router when you program the console connection, the command is 'line con vty', which stands for Virtual TeletYpe... just some useless trivia! Aah, texting...the way my generation communicates...my parents just don't understand

What get's me about texting is when the participants are adjacent to each other! I suppose that way, no one can eavesdrop, and they can say things they don't want others to hear. If that's the reason, maybe they need to find something more productive to do?  John C.

Cell phones (they are not telephones, they are radios), are hellspawn.
I refused for a very long time to use a cell. My last job forced one in my hand.
When I wasn't using a cell, one of my friend's from high school asked me how people would get in contact with me. I said: "They don't." HA!
Call me at home, if I'm not there, leave me a message and I'll get back to you. WHAT'S SO DIFFICULT ABOUT THAT!? IT WORKED FOR THE FIRST 25 YEARS OF MY LIFE!
Cell phones...the ultimate way your pr**k of a boss can keep you at work 24/7.

Guess I didn't pay much attention when I posted. These post are drifting all over the place. Let's get her back on topic. Thanks.

OK, back on topic:
I think I screwed up when I rewired the cord to my 564. If you recall, I rewired it as a 565, with an individual ground for each lamp. But there's a problem.
I get DT for line 1 and line 2 (only have two lines total), but when line 2 is recieving incoming call, the lamp lights up very dimly, in unison with the lamp for line 3.
The lamp works fine for line 1
I was wondering if it had anything to do with the way I wired the A and AI connectors.
Inside my 564, the AI terminals are in a row above the line terminals segment, with a letter code facing the rear end of the phone.
The letter markings for the AI terminals are as follows from left to right looking at them with the rear of the phone facing you:
B(or 1B, can't really make it out)
EB
EH
ET
ER
then two terminals marked as SG.
The corresponding A terminals are
1H
2H
3H
4H
5H
The way I wired them is as follows:
1H-white/orange
B(or 1B)-orange/white
2H-white/slate
ER-slate-white
3H-green/red
ET-red/green
4H-blue/black
EH-black/blue
5H-brown/black
EB-black/brown
I don't know if that's where the problem lies.
