Are ion engines broke???

@SupremeDorian it says total thrust = 0 on the popup window

@jetnyan no, i know they suck on the ground, but when i have every part needed, they never seem to work

it took me a couple of tries, and some help to get the ion engine to work - my try produces 20N (0.020kN) of thrust, and will only move a really light satellite(so far) - but it needed a command chip xenon battery, regular battery, solar panels, and the ion engine (i turned the "fuel line" on each part)...but it still runs out the battery faster than the solar panels charge it. im not sure if the battery recharges the xenon battery, but my small xenon tank is still at 100% after a bunch of burns that ran the regular battery down. i uploaded it, if its any help to look at

Are you trying to take off with them? Watch a video of a real life test on one, and you’ll see how much thrust they produce

Are they able to crossfeed? also use solar panels to regen power

They're most likely producing thrust, just not much. They are very efficient, but they also have very low thrust. They're meant for long deep space burns.
