Spacelog Apollo 13

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

Okay, Vance. How are you reading now?

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

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

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.

Okay. Stand by.

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.

That is verified on. I checked that.

Okay.

Okay, Jack; this is Houston. Over.

Go ahead, Vance.

Okay.

Or it's —

— Stand by. —

— that MAIN B is closed.

Okay.

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

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

Copy.

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

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

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?

Okay, we'll get —

— by all means and —

— down there —

— select best OMNI —

— and then go back up.

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.

Okay. And select best OMNI.

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

Loud and clear.

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

Roger.

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

Reading you loud and clear, Jim.

Okay.

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

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

That's affirm.

Aquarius, Houston.

Go ahead, Houston.

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.

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

That's affirm.

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.

Houston, Aquarius.

Go ahead, Aquarius.

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