Yes, help indeed!

For someone who just found out what tip and ring meant less then a month ago, I think I'm doing pretty good. I think there's noise on line 2 because the connectors are not punched down particularily well. (I don't have a punch tool).

Of course I may be talking complete nonsense, but if I knew everything already I wouldn't be here.

Quick question:

Thanks to Ed's expertise, I managed to get ringing on line 2. Problem was I had not connected a jumper between CA1 and CA2 (I only have two lines, so I don't need more).

But there was another jumper running between one of the B1's and R1's that I removed, and things aren't going well since I removed that one.

Could someone tell me where I would have to apply that jumper, since I can't remember from where I removed it? (Alzheimers at 35, not good)

Many thanks.

Not true. I know everything already, and I'm here.

Strap the CA ("Common Audible") terminals for as many lines as you want to ring at the same phone(s).

Wohoo! There be life in them old wires!!!

Thanks to Ed's unquestionable expertise, my KSU 551 is now fully operational. Somehow I had managed to blow the 10VAC fuse. Luckily there was a spare next to it. I also placed a jumper between CA1 and CA2, and I get two sweet rings.

All's good. Lamps flashing, bells ringing. I'm so happy I could cry! I really thought I had killed the unit by removing the jumper between MB and LB.

Arthur, obviously modesty is one of your virtues.

"Motor Battery" and "Lamp Battery" if memory serves me correctly....

I'm not too forgetful....as justbill says "I can hide my own Easter Eggs".......

Yes, motor battery and lamp battery as Ed told me. I can't quite figure out how a battery comes into the equation, since the unit is plugged into a 120 source, but I'll take it one step at a time

Battery is just terminology that the Bell System used to refer to voltages being provided by power supplies. Maybe this dates back to the days when power for the phone network really was provided by batteries. Who knows?

Our resident vintage Western Electric guru (Arthur P. Bloom) might chime in with a real answer to your question.

I'd be happy to know half of what he forgot.

Battery in reference to dc voltage v AC voltage,and yes I have even worked on manual I/C with the big "Blue Bell" 1.5 batteries hanging on the wall in a canvas bag ( Bell system Logo on it no less)
