I have a 2021 Mercedes Sprinter van that I installed a victron system in, complete with 2 Victron batteries, multi plus inverter, lynx distributor and the BMS 12/200. I cannot get the alternator to charge the system. I know power is coming from the alternator, I have checked the wire. I attached all the included wires, but was also confused at what a “remote on/off” was. The alternator comes into the BMS, the middle Li-Ion Minus goes to negative on the battery and the system exits into the positive bus bar of the Lynx distributor. I have the remote on/off (I think) wires hooked into the ”remote” and they go to the positive lug of the battery. Any suggestions or changes I could try?
