excuse me, I have tried connecting two vehicles with an extension cord, it gave me the message "You link up the electric systems of and ", but I don't see the systems as actually linked and I also can't now remove my cable either? It has just straight up disappeared. I tried the same thing with another cable and the same thing happened.

Are you sure you're running an up-to-date build? I just tested it with two cars and two welding carts and it works as expected. I even tried it across overmap boundaries just to check and it's balancing power properly.

Can you create a new issue and attach your save?

Maybe i'm just using it wrong? I go "a"ctivate->extension cord, select a vehicle with the engine turned on, then I hit "a"ctivate again, the extension cord is now highlighted yellow and says that one of its ends is attached, then I select the other vehicle (which is one tile apart), it says that their electric systems are now connected and the cable disappears from my inventory.

But I don't see any indication of the battery in one vehicle being charged by the running engine (with an alternator) in the other one. I also don't see a way to remove the cable. How am I expected to detach the cable?

I am running experimental from about 5 days ago.
