Citreon xara picasso

i have just put a new battery on mine and now my dashboard comes when i turn the key then goes off when you turn on the ignition

Almost all of us are Americans and don’t know how to spell Citroen Xsara Picasso, either. Citroen hasn’t been sold her for 36 years.

If I understand correctly, the dash warning lights go on when turning the key past the “on” position to the “start” position and then go off when the engine starts?

If my understanding of the post is correct, everything is operating properly.

Why is my gut telling me I’m not understanding correctly?

Check you grounds, especially battery to chassis and/or block or however the frogs wired it.
