ten25 Posted July 25, 2022 Share Posted July 25, 2022 (edited) Hey all. I managed to get my Renogy DC DC Charger hooked up and working. I followed the wiring in the Renogy instructions and used a fuse tap on F42 in the engine bay (rear window wiper, it only comes on when the vehicle is on. Best part is my solar charge controller will shut off when the DC DC charger is going (although I think I was at around 70-80% before turning the car on - not sure yet if it will shut off if the battery is lower). I think this might be a good thing to keep the batteries from charging too quickly, although if you have a big enough bank maybe not ... I take no responsibility for anyone copying this setup blowing themselves up. In fact I almost blew myself up when I accidently connected the positive and negative on my battery with my wrench (doh). Never managed to do that until this install. I really really hate the place Ford put the battery in this car.

ten25 Posted July 28, 2022 Author Share Posted July 28, 2022 Turns out the solar does work simultaneously with the DC DC Charger - if the battery is depleted enough. For me, that is a good thing! Quote Link to comment Share on other sites More sharing options...
ftc71 Posted September 21, 2022 Share Posted September 21, 2022 Hey, congrats on your install! Can you show how you did it? I'm having trouble figuring out where to route the wiring. Quote Link to comment Share on other sites More sharing options...
steve.b Posted April 26, 2023 Share Posted April 26, 2023 The fuse box forum just gave me this idea. One guy was going to connect the D+ connector to the fuse box in the engine compartment, just so he could have his webcam ONLY ON when the vehicle was on. So he used the USB port in the Transit Connect (which turns on and off with the ignition). https://www.amazon.com/PEMENOL-Adjustable-Supply-Voltage-Converter/dp/B07V5FPNNZ This is a 5V USB step up buck converter. So I can plug this into the USB port, run a USB cable to my Renogy 40A DC to DC charger to the D+ signal port. No need to access the fuse box in the engine compartment anymore just for a 12V signal that turn on the charger. Quote Link to comment Share on other sites More sharing options...
