13, Houston. We're going to have to have you go through the shutdown procedure on fuel cell 1. Our O2 pressure is going down as you note and the temperature confirms it. Did you copy?
- Jack Lousma (CAPCOM)
-
Okay, Jack. We want you to leave the bus configuration as it is. Fuel cell 2 on MAIN A, and we need OMNI Bravo.
- Jack Lousma (CAPCOM)
-
And, 13, Houston. We'd like you to isolate the REPRESS package, please.

Roger. So now you've got the REPRESS package and the surge tank isolated. Is that affirm?
- Jack Lousma (CAPCOM)
-
Okay, 13. We verify that we want you to close down—shut down fuel cell 1, close REACs valve.
- Jack Swigert (CMP)
-
Okay, Jack. I can confirm step 2. The fuel cell shutdown procedure is complete for fuel cell 1.
- Jack Lousma (CAPCOM)
-
13, Houston. We're working on the big dish now, so turn the HIGH GAIN POWER switch off, please.
- Jack Swigert (CMP)
-
Okay, Jack. When we got the loud bang, we got also a restart. Did you copy that? Is—does GUIDO want anything, a VERB 74 or anything done with the CMC?
- Jack Swigert (CMP)
-
Key moment With oxygen dropping, the crew considers a move to the LM: Okay, Jack. It looks like O2 tank 1 pressure is just a hair over 200.
- Jack Swigert (CMP)
-
Yes. That's what we're thinking about, too. You want me to do a quick P52? It kind of looks like—We've been talking it over, and it kind of looks like we'd probably aline our plats—LM platform with our platform and then power down the CM, and keep the LM powered up doing a DPS—whatever DPS burns you give us?
- Jack Lousma (CAPCOM)
-
13, we're not going to concern ourselves at the moment with a DPS burn. It's going to be some time before we'd get to that; but we're working on other procedures to give you, which will allow us to use the LM systems. Over.
- Jack Lousma (CAPCOM)
-
And, Jack, in regard to your question about the P52 and LM platform, it's—There's no need to worry about that now. We wouldn't be using the LM platform for—until about 79 hours, so let's go as is on the platform for now. Over.
- Jack Swigert (CMP)
-
And, Jack, we've turned off the waste dump heater. If you're going to consider dumping any more waste water, we probably ought to do it while the duct is warm there.
- Jack Lousma (CAPCOM)
-
Okay, Jack. Let's keep the water; no need for a dump right now.

13, Houston. We see the PROP ISOL valve on RCS quad Charlie closed, so we'd like to also disable AUTO RCS feature in quad Charlie.
- Jim Lovell (CDR)
-
Okay, Jack. I didn't plan to reset that quad Charlie DROP ISOL valve. Do you want me to do that? Okay. We just tried it and quad Alfa and Charlie barber poles are showing.
- Jack Swigert (CMP)
-
Okay, Jack. That's the sec—secondary propellant barber poles on Alfa and Charlie.
- Jack Lousma (CAPCOM)
-
13, Houston. It won't do any good to try to power the propellant valves on A and C, so we want you to disable the AUTO on RCS Charlie. And we have a procedure for getting power from the LM we'd like you to copy down.
- Jack Lousma (CAPCOM)
-
It's not a very long procedure, Fred. We figure we've got about 15 minutes' worth of power left in the command module, so we want you to start getting over in the LM and getting some power on that. And, you ready to copy your procedure?
- Jack Lousma (CAPCOM)
-
Okay. In the CSM on panel 5, circuit breakers LM POWER 1 and 2, OPEN. Then LM POWER switch, reset and release. In the LM, on panel 11 and panel 16, TRANSLUNAR BUS TIE. Both circuit breakers CLOSE. On panel 16, circuit breaker ASCENT ECA CONTROL, CLOSE. On 16, DESCENT ECA CONTROL, CLOSE. On panel 14, put your BAT 5 NORMAL feed ON. BATs 1, 2, 3, and 4 LOW VOLTAGE taps, ON. BAT 5 NORMAL feed, OFF. ASCENT ECA CONTROL, OPEN. You copy?
- Fred Haise (LMP)
-
Okay. In the CSM, on panel 5, we want CB LM POWER 1 and 2, OPEN. Then the LM POWER switch to reset, release. In the LM, panels 11 and 16, X LUNAR BUS TIE breakers closed. On panel 16, the ASCENT ECA CONTROL closed; the DESCENT ECA CONTROL closed. On panel 14, BAT 5 NORMAL feed ON, followed by BATS 1, 2, 3, and 4 LOW VOLTAGE taps ON. Then BAT 5 NORMAL feed OFF. Then ASCENT ECA CONTROL breaker OPEN.

And, 13, Houston. As a final effort here, we would like you to turn on the fans in tank 2. Over.
- Jack Lousma (CAPCOM)

It's just four lines. Go to Activation 1, do step 3. Go to Activation 11, omit step 1. Do Activation 12, and then go to Activation 13 and do step 1. Do you copy?
