Ken Mattingly: [after another power-up simulation fails] I know this sequence works, John. John Aaron, EECOM Arthur: The sequence looks good, we're just over budget on the amperage. Ken Mattingly: By how much? John Aaron, EECOM Arthur: Three or four amps. Ken Mattingly: Goddamn it, John! Is it three or four? John Young: Four. John Aaron, EECOM Arthur: Four! Ken Mattingly: [sighs] Four more amps... [He ponders for a moment] Ken Mattingly: We know they have some power left in the LEM batteries, right? John Aaron, EECOM Arthur: Yeah. Ken Mattingly: We have an umbilical that provides power from the Command Module to the LEM. John Young: Right. It's a backup for the LEM power supply. John Aaron, EECOM Arthur: I'm listening. Ken Mattingly: So, reverse it. Reverse the flow and see if we can draw these four amps from the LEM batteries before we cut it loose. Why can't we do that? John Aaron, EECOM Arthur: [Looks at John] We don't have a procedure for that, do we? John Young: You're gonna lose a lot in the transfer, Ken. Ken Mattingly: Yeah, yeah. But all we're talking about here is four amps.
