Not enough information.
One thing I learned very early in life was when I did something and things did not work anymore go back a double check all your work. You should have taken photos with your cellphone before you disconnected anything. Chances are you connected something wrong or left something disconnected.
So when you turned the engine off did the power come back?
Are you talking about the house batteries or the engine battery?
Which battery (batteries) were you changing? House or chassis
