I've noticed a lot of players using engines that require electricity and becoming confused about how their fuel bar suddenly goes to 0%. The game doesn't seem to effectively communicate to the player when an engine needs electricity, or that they no longer have enough to use the engine. I think it would be nice to see some improvement here.
to be honest, a simple "[name] ([part ID]) cannot function due to a lack of electricity." (or similar text, for example, replacing the "cannot function" with "can no longer function") could easily solve this, but this is just my opinion
