Thanks! Life support was set to inactive after i overloaded power trying to use new weapons etc. Seems strange that it doesn't just disable weapons etc instead.
You should probably set your module priorities to something like this.
1. Life Support, FSD, Thrusters, Power Distributer, Sensors.
2. Shields and other defence, Fighter Hanger, Power Distributer, Sensors.
3. Weapons.
4. Fuel Scoop, SRV Hanger.
5. Cargo Hatch.
The items in italics are the ones I switch round in attempt to keep the priority 1 items at 40% or lower of total power, if you can do this they should keep working after a fashion no matter how low your power supply gets due to damage.
Why have FSD at 1 - you can't use it with the hardpoints extended.
I always set it to 4 - not that it ever gets "disabled" ever since that nice Flic gave my Vulture power gen a bit of a leg-up.![]()
When priority setting was brought to my attention I read that items in priority 1 would always get enough power to work even if your power supply was down to 1% as long as the priority 1 items didn't consume more than 40% of the power supplies original output, it is apparently why the 40% line turns blue on the coriolis shipbuilder display if you achieve that. So it isn't a measure for dealing with starting out with more kit than power but an emergency get you home in your new space going colander measure.
And no I have no idea where I read this, I have been sober since then, but it is most likely to be here, the CG forum or Dangerous Discussions.
