Ford Think problem

Brand new to me Ford Think, just needed batteries. Installed new batteries and everything worked, then the following day no headlights, turn signals, the cluster works but doesn’t illuminate, the brake light symbol on the cluster stays on also. Any suggestions?

Disregard, new dc/dc converter fixed all except the cluster backlight. Occasionally reverse isn’t working, gonna trouble shoot when I get time.

Did you ever solve the problem as to why your think did not go in reverse. I am having similar issue. Also what converter did you get?
Thanks bob
