48-7S "Spark" Not Activating on Staging

[Geschosskopf]

This has been bugging me for a while now....

Is there a way to make the 48-7S automatically activate when it's staged? ModuleManager patch or something? Even when it's on the staging list, I still have to right-click to activate it.

Not seen that in normal usage Geschosskopf, but I just tested with a pod, spark and decoupler alone and replicated it. Maybe because it didn't have any fuel? Otherwise, no ideas yet.

I've never seen this, and I use the Spark quite a lot (it's one of my favorite engines). It acts normal for me, i.e. the same as any other engine where staging is concerned. What mods are you running, any possibility of odd interference there?

[Geschosskopf]

Hmmm, maybe it's more correct to say what mods Im NOT running ;). Oh well, thanks for checking. I'll fiddle with it and see what's going on.

Not the fairing thing? Or crossfed tanks? The latter is usually the surprise I get. "Now I know where that magic DV came from"

I had that happen to me yesterday with a Terrier. Throttle was maxed, I hit space several times, hearing the 'click' each time, and finally had to right click to light it. I've used a similar sat/vehicle combo (Okto with early science gear, nose cone, fuel tank, Terrier, all on top of a Kickback) many times; I think the only difference with this one was the ScanSat radar antenna.

I didn't have time to look into it further, unfortunately. Edited November 16, 2015 by StrandedonEarth

[Right]

I've had this happen with seperatrons on certain rockets. I canned the designs unwilling to uncover the source of the bug.

It sounds like it's the "Cannot activate while stowed" thing when you deploy fairings on the same stage as igniting the engine. I've had conflicting reports on whether having them in a different order on the same stage fixes it.

Look for the "Cannot activate while stowed" message on screen when you stage.

I could be wrong, a screenshot of the craft that causes this would help diagnose the issue.
