LCD Display - GEM Car

Hi All,

I just replaced by LCD screen in a 2005 GEM 825S. While the key is on and I’m riding down the road, the screen shows that same display that would show when batteries are charging. When I park and hook charger up, it shows “charging cord” icon and the red light bar stays steady while all other light bars constantly blink.

Can anybody assist in what I should do to fix this issue?

I appreciate any help.
