Gem e6 2010 problems

I just replaced the charger and 9 new 8v batteries. When I went to turn it on the display lights up when I go to drive I get nothing. The display shows the headlight symbol and the brake symbol even when the brake is all the way down. I took the connectors off and tried to jump the two on the e brake switch and the light still stayed on. None of my 12v accessories are working either. I checked the fuses and they are fine. Any ideas on what to do?How do I fix this thing to get it to move?

you probably need to make sure the charger is configured to charge your batteries. Not talking about just connecting wires, there should be settings for the charger based on the type of batteries you installed( Lead acid/wet, AGM, Gel ).
