Interesting. Is that for temperature management?
Not sure why, but that might be the reason
Thank you for that information, I get that error regardless if all the cables are connected or not. Could I possible be missing something else for the cart not to charge?
You said you used the harness from another car, where did you plug the harness? There should be 3 places, the chargers. The interlock by the horn and the communication by the service port next to the charging port receptacle
The harness is original to the cart and the chargers. I did not use a different harness to connect these chargers.
Send pics of where the harness is connected, there should be 3 places where the harness plugs to the car…

I have a video, I just can’t figure out what the best way to upload it is.
Try to connect them backwards swap sides charger A and B only the data port,
also make sure the above connection is properly connected, identify the Main service plug, then every accesory has a Y make sure you are not connecting the same Y split together and you are really doing a cascade, put the Charger harness Y split in the first one (directly to the main service port) and see if that solves the issue,
did you replace the bmc next to the speed controller or just the brammo? If you did not do it your car might still be programmed for Agms be careful
