Joe Kerwin (CAPCOM)

Okay. That's correct, Jack. And now we'll go into the main bus powerup procedure. And the first step there, is on panel 5. We want the BAT CHARGER BAT A CHARGE circuit breaker closed, and the BAT CHARGER BAT B CHARGE circuit breaker closed. Over.
-
Jack Swigert (CMP)
-
Okay. That's BAT CHARGER BAT A CHARGE, BAT CHARGER BAT B CHARGE, both closed on panel 5.
-
Joe Kerwin (CAPCOM)
-
That's affirmative. We need them closed to power the switches. Next on panel 5, we want the EPS SENSOR SIGNAL MAIN A and MAIN B circuit breakers closed. Over.
-
Joe Kerwin (CAPCOM)
-
Okay. That's affirmative. We need them closed so that you can read out your volts and amps. Next step, on panel 250, we want circuit breaker BAT A POWER ENTRY and POSTLANDING and BAT B POWER ENTRY and POSTLANDING, closed. Over.
-
Jack Swigert (CMP)
-
Okay on panel 250, CB BAT A POWER, ENTRY and POSTLANDING, closed; BAT B POWER ENTRY and POSTLANDING, closed.
-
Joe Kerwin (CAPCOM)
-
That's affirmative. And at that point, we'd like you to check the BAT bus voltages on both BAT buses to make sure we don't have any shorts. Over.
-
Joe Kerwin (CAPCOM)
-
That's affirmative. The next step on panel 275: circuit breaker MAIN A, BAT BUS A, closed, and circuit breaker MAIN B, BAT BUS B, closed. Over.
-
Jack Swigert (CMP)
-
Okay. On 275, circuit breakers MAIN A, BAT BUS A, closed; MAIN B, BAT BUS B, closed.
-
Joe Kerwin (CAPCOM)
-
That's affirmative. The next step on panel 5: we want the MAIN BUS TIE A/C switch to the BAT A/C position, and verify proper voltage on MAIN BUS A, and read the amps on BAT A to make sure we don't have a short. Over.
-
Jack Swigert (CMP)
-
Okay. Place MAIN BUS TIE A/C, on, read MAIN BUS A current and voltage.

Joe Kerwin (CAPCOM)
-
Okay. That's affirmative. The next step will be the MAIN BUS TIE B/C switch to the on position and read MAIN B voltage and battery B amperage as above. Over.
-
Joe Kerwin (CAPCOM)
-
Okay. That is correct. Then to reconfigure from this configuration, Jack, we want you to leave the MAIN BUS TIE switches in the on position and pull the circuit breakers out in reverse order that we had you close them. Over; and do you want me to read them up individually?
-
Jack Swigert (CMP)
-
No, let me see if I've got it here. I go down to panel 275, open CB MAIN A, BAT BUS A and CB MAIN B, BAT BUS B. Then I go down to 250, and pull CB BAT A POWER ENTRY/POSTLANDING and BAT B POWER ENTRY/POSTLANDING and then up on panel 5, pull EPS SENSOR SIGNAL MAIN A, SENSOR SIGNAL MAIN B, BATTERY CHARGER BAT B CHARGE, BATTERY CHARGER BAT A CHARGE. And then close—I don't know whether you want me to close the RENDEZVOUS RADAR TRANSPONDER FLIGHT BUS and S-BAND TRANSMITTER/DSE FLIGHT BUS.
-
Joe Kerwin (CAPCOM)
-
Okay, Jack. We don't want you to close those last two. Those are changes to your basic configuration, and we want to leave them open for now. Over.
-
Jack Swigert (CMP)
-
Okay, Joe. And just for confirmation, I went through the switch list you gave me. We are in exactly that configuration with one exception, and that is over on panel 382. I have not, the a—H2O ACCUMULATOR is in the OFF position so that if we need any more water, we can get it.
-
Joe Kerwin (CAPCOM)
-
Okay. Roger, Jack. Copy that. On panel 382, you've left the H2O ACCUMULATOR valves in the OFF position, and we concur.
-
Jack Swigert (CMP)
-
Okay. And there's one other thing that I don't know whether you're aware of. We have no lithium hydroxide canisters in panel two fif- in—canisters now. So when we get ready to power up, you'll have to remind us when you want us to add some.
-
Joe Kerwin (CAPCOM)
-
Okay, Jack. We copy that. That's correct, and I'll add that to our basic checklist so that we won't forget it.
-
Fred Haise (LMP)
-
Okay. I'm back on the line now, but Jack really … headed back to the upstairs bedroom.
-
Joe Kerwin (CAPCOM)
-
Okay, Fred. We recommend that you push your MASTER ALARM circuit breaker in so you'll have audio and visual on that, and, also, we medical types are getting to feel left out down here, and we'd like you to give us BIOMED … position, if you're plugged in for it, and we'll see whether it affects the voice or not. Over.
-
Joe Kerwin (CAPCOM)
-
Aquarius, Houston. Go ahead.

Fred Haise (LMP)
-
Okay, Jack just … himself back down. And after he put on the 250 BAT A, BAT B breakers, he read BAT bus volts as 32.3 on A, 37.0 on B; he then punched in the 275 breakers, which tied the batteries to the buses, and at that time he read the A bus volts 32.0 on A, zero amps; 37.0 on B, zero amps.

Joe Kerwin (CAPCOM)

Aquarius, Houston. The COMM got noisy there, and I want to make sure we get these numbers right, so I'd like to ask you to repeat them …
