Vance Brand (CAPCOM)

Okay. You faded out at the very beginning, so please go through that again. We understand you don't get anything on MAIN B.

Jack Swigert (CMP)

Okay, Vance. How are you reading now?

Vance Brand (CAPCOM)

Okay. We're hearing you better. Stand by 1.

Vance Brand (CAPCOM)

Okay, Jack. Please, repeat back now your conversation. You were cut out for—a while ago.

Jack Swigert (CMP)

I don't have any idea where we cut out, Vance. I just said that we performed the procedure exactly as you say. We're down into the SEP critical portion to where I said, “select best OMNI.” However, we're not getting any MAIN BUS B voltage reading. I can read BAT BUS B, Baker, at 36.5; BAT Charlie at 37.0, but I have negative MAIN BUS B readings.

Vance Brand (CAPCOM)

Okay, Jack. There are two—There's a switch and a circuit breaker that were positioned this morning that we'd like to have you check—Correction, just the switch. Panel 5, check your bus tie. MAIN BUS TIE BAT B/C on.

Jack Swigert (CMP)

That is verified on. I checked that.

Vance Brand (CAPCOM)

Okay, Jack; this is Houston. Over.

Vance Brand (CAPCOM)

Okay. We're getting data from you, Jack, so that much looks good. On panel 5, request verification that EPS SENSOR SIGNAL circuit breaker is MAIN B. Over.

Vance Brand (CAPCOM)

— that MAIN B is closed.

Vance Brand (CAPCOM)

Okay, Jack. And, we see your MAIN BUS B voltage at 28-1/2.

Jack Swigert (CMP)

Okay. You can see it. Good. Okay then. Okay, Vance. That circuit breaker is in.

Jack Swigert (CMP)

Well, Vance, if you're getting data from them, let me go back up there and finish the …

Vance Brand (CAPCOM)

Okay, Jack. Please repeat, you're cutting out.

Jack Swigert (CMP)

Okay, Vance. Okay. We just changed OMNIs here. I say, if you're getting data from us, that's the important thing. Let me go back up into the bedroom there and get the readings you wanted, so we can get this stuff powered down. Is that okay?

Vance Brand (CAPCOM)

— by all means and —

Vance Brand (CAPCOM)

— select best OMNI —

Jack Swigert (CMP)

— and then go back up.

Jack Swigert (CMP)

Okay, Vance. We'll go back up—We've got voltage now, and we'll go back up and take the readings that you want.

Vance Brand (CAPCOM)

Okay. And select best OMNI.

Jack Swigert (CMP)

Okay. I'm going back up into the bedroom, Vance. How do you read?

Jack Swigert (CMP)

Okay. I'm going back up to the bedroom. We'll select best OMNI and continue on with the procedure.

Jim Lovell (CDR)

Okay, Vance. Jim's up. How do you read?

Vance Brand (CAPCOM)

Reading you loud and clear, Jim.

Jim Lovell (CDR)

And, Houston, I noticed through the AOT and through the overhead docking window that we are venting again.

Vance Brand (CAPCOM)

Okay, Jim. Understand; the service module is venting.

Vance Brand (CAPCOM)

Jim, would you holler into the bedroom and tell Jack that when he has his onboard readouts that we wish he'd back—use the backout procedure and shut down again—per the procedure we gave him.

Jim Lovell (CDR)

Roger. As soon as he—As soon as he gets his onboard readouts to use the powerdown procedure and shut down. Is that right?

Jim Lovell (CDR)

Okay. Jack just—Jack just told me that he's through, and he's going to go through the backout procedures again, the first one he's got is the shutdown.

Jim Lovell (CDR)

Jack's ready to give you the readings if you are ready to copy them.
