Did it start before battery replacement? Why did you replace it?

Did you reconnect all the connection? Obviously + and - terminals but did you reconnect the small 2 pin connector?

Do you have power to accessories or Hazards? If so, there is probably something loose on the red cut-off box that sits on top of your battery. Power comes from the battery on two circuits (as far as I know). One circuit runs your lights, flashers, etc, and it is the wire on the battery itself. Another circuit runs the motor and some other high-draw devices, and it is routed through the red device on the battery that supposedly cuts the power in an overturn accident for safety. There are some wires on there, that may have come loose. Hope this helps.

Is the new battery fully charged?..did you connect everything correctly?

I wonder what happened with this. Was there something not connected or an issue w/ the new battery?
