Gemini 1 Runaway

[Boozlefoot]

Recently starting to setup in the new obs, I was adjusting the clutches on the MI250 - the Gemini 1 control fired up on it's ownsome. (I was nowhere near the controls, so it wasn't a "bump start")

Wasn't overly concerned, thinking it would pull up on the limiters - but it didn't - resultant RA servo collision. :mad2:

I'm thinking this glitch may have reverted the Gemini back to factory settings, thus Sth becomes Nth again, and it has inverted the limiter settings, resulting in the collision.

Has anyone else experienced a Gemini runaway?

Neil Armstrong and David Scott did, but I suspect that's not the answer you were looking for.

:D

Boom boom.:lol:

On further reflection, the obs is currently on the same wiring circuit as a rather large automatic water pump. I think the probable cause of the runaway start could be the resultant voltage drop/spike, thus initiating the Gemini to revert to factory defaults and Cold Start.

Gemini to be removed, remove/discharge CMOS and remodel/start again! :question:

And of course, an AGM battery now to be fitted to the obs with a 12v trickle charger to stabilise/buffer the input voltage to the Gemini.
