Does my 2018 Ford Transit have a smart alternator if it reads 14.4 volts? I'm installing a Renogy DCDC 30S, DC-Dc charger and it says if my alternator reads 14.4Volts then its most likely a traditional non smart alternator. Then i wouldn't need to attach the ignition signal wire
Would suggest a B2B charger. Not only does that solve the problem (no ignition signal wire required), but it will charge your leisure battery far more quickly, and prolong it's health, too.
