Fred Haise (LMP)

Okay, Jack, are you monitoring the quad temps in quad A—package temps?

Jack Lousma (CAPCOM)

13, this is Houston. We'd like to power down just a little bit more, so let's get BMAG 2 OFF; and make sure your lights are down. Over.

Jim Lovell (CDR)

Okay. The lights are down, and BMAG 2's going from STANDBY to OFF.

Jack Lousma (CAPCOM)

— we'd like you to open circuit fuel cell 3.

Jack Swigert (CMP)

Open circuit fuel cell 3.

Jack Swigert (CMP)

Okay, fuel cell 3 is off the line now.

Jack Lousma (CAPCOM)

And 13, Houston. We'd like you to turn all your Bravo thrusters OFF; and put all your Delta thrusters on MAIN A, please.

Jim Lovell (CDR)

All Delta thrusters on MAIN A and all Bravo thrusters OFF. Roger.

Jack Lousma (CAPCOM)

13, Houston. Turn BATTERY A OFF —

Unidentified crew member

Jack Swigert (CMP)

That's right; we were pulling current all the time.

Jim Lovell (CDR)

BATTERY A OFF. Roger.

Jim Lovell (CDR)

I'm transmitting. I don't have any current now.

Jack Swigert (CMP)

Hey, it's off—it's off. They—they killed the bus completely now.

Jack Lousma (CAPCOM)

13, Houston. We'd like you to isolate your O2 surge tank. Over.

Jack Swigert (CMP)

Surge tank off now, Jack? Okay, Jack, are you copying—O2 tank 1 cryo pressure?

Jack Lousma (CAPCOM)

That's affirmative. And we're trying to get power to that tank. Stand by; we're working on it.

Jack Swigert (CMP)

Okay. We had a—SERVICE MODULE RCS B light, jack, due to package temperature.

Jack Lousma (CAPCOM)

SERVICE MODULE RCS B. We copy. No problem.

Jack Swigert (CMP)

Let's read you the lights we got on now; CRYO PRESS, FUEL CELL 1, FUEL CELL 3, MAIN BUS B UNDERVOLT, SUIT COMPRESSOR.

Jack Lousma (CAPCOM)

Roger, we copy them and we'd like to build up the pressure in O2 tank 1, so turn the heaters on manually; we'll watch the pressure for you.

Jack Swigert (CMP)

Okay, do you want to see —

Jack Swigert (CMP)

— We're going to get a MAIN BUS A UNDERVOLT, probably.

Jack Lousma (CAPCOM)

Roger. We realize that; we feel we can stand 5 more amps on it.

Jim Lovell (CDR)

Okay, heater on tank 1's ON.

Jack Lousma (CAPCOM)

13, Houston. We'd like you to additionally bring on the fans in O2 tank 1, and we can stand the additional amperage on that.

Jim Lovell (CDR)

Okay—bring up the fans on O2 tank 1.

Jack Lousma (CAPCOM)

13, Houston. We'd like you to check some circuit breakers on panel 226. CRYO O2 HEATER number 1 MAIN A, and check the three CRYO FAN MOTORS, TANK 1, three phases.

Fred Haise (LMP)

Okay, Jack. 226 is configured just like it should be. I got three REACS breakers and three RAD breakers open. All the rest are closed.

Jack Swigert (CMP)

Jack, looking outside, the number of particles has diminished greatly, almost ceased now, which indicates maybe what was venting has almost stopped.

Jack Lousma (CAPCOM)

Roger, Jack. Thank you. We copy.

Jack Swigert (CMP)

I'm still getting some rates in negative pitch, though.

Jack Lousma (CAPCOM)

And, 13, we'd like to verify that both BMAGs are off, please.

Jack Swigert (CMP)

Negative. We just have one BMAG. BMAG number 1 is still on.

Jack Lousma (CAPCOM)

Okay, Jack. Let's take BMAG 1 off.

Jack Swigert (CMP)

Okay. BMAG number 1 off now.

Jack Lousma (CAPCOM)

13, this is Houston. We'd like you to give us a survey of your displays on MDCs 1 and 2. Give us gage readings and talkbacks. Over.

Jim Lovell (CDR)

Okay. We'll start with display number 1.

Jack Swigert (CMP)

Okay, Jack. On MDC 1, there's nothing abnormal. All the rate indicators are zero. Ball number 2 is frozen, of course; we lost MAIN B. I've got—Ball number 1 appears to be working normally. Right now I'm sitting at roll 0, pitch 180, and yaw about 13 degrees. I'm going to try and hold 0, 180, and 0.
