Check continuity on O2 cryogenic tanks before allowing stir

[NoraCodes]

A customer has had a fairly serious problem with stirring the cryogenic tanks with a circuit fault present. To reproduce:

1. Build CSM
2. Perform mission up to translunar coast
3. During translunar coast, attempt to stir cryo tanks

If a wiring fault exists, the issue may be replicated. Be aware that this may be hazardous to the tester attempting it.

i think this issue should be closed because we can't reproduce it

[lbotinelly]

Does it happens only with translunar coast (sol-3-a), or any moon coasting? It may be a problem with the moon. Just trying to narrow down the issue.

Have you tried turning it off and on again?

This is fixed in Apollo 14.

[adampats]

This is a hardware problem. I suggest a wontfix and close.

In other words: "What was that gauge reading before you hit the switch?"

@adampats Hey, don't tell me how to fly the CM, all right? They brought me in here to do a job, they asked me to stir the tanks, and I stirred the tanks!

As a temporary solution, you could try gently rolling the CM/LAM to agitate the O2. You may need to do it on the X and Y axis to get optimal agitation.

@SilverWingedSeraph could you provide a screen shot of the error I should expect to see during repro?

[AdamFreemer]

Let's work the problem people.

[NoraCodes]

@chrislgarry It looks a little something like this:

Which version of Apollo are you running? I suggest upgrading to Apollo 12

[lbotinelly]

Not specifically for this issue, but maybe we should consider trimming down. I'm pretty sure we can automate this, eliminating both meatbags and O2 tanks from the final implementation.

Have you tried migrating your project to jQuery?

[AdamFreemer]

Many bug fixes were addressed in Apollo 18 mission software, until the bugs infected the astronauts.

It works for me
