How To Charge Trailer Batteries With Vehicle Battery
Question:
I cant find #SW1520 part you described. Charging trailer batteries directly from tow vehicle batteries
asked by: Michael
Expert Reply:
The wiring kit you mentioned is no longer available but I do have a way for you to charge your trailer batteries with the tow vehicle. I recommend to use the Redarc In-Vehicle BCDC Battery Charger part # 331-BCDC1225D which is designed to charge the trailer's batteries from the vehicle's alternator. The Redarc has a battery isolator so the trailer cannot pull power from the battery when the ignition is off. This is a safer way to charge the trailer batteries instead of just running a wire from the vehicle's battery to the trailer's battery. I also recommend to use the fuse kit part # 331-FK40 to protect your setup from short circuits. I have attached an installation video for your reference.
