It wasn't going to work with my alternator to have a dcdc on the cranker, and it wasn't really necessary. When I bought two I thought I'd give it a go just to be different, see if I could make it work, but it was just adding layers of complexity to make it work, all just to get a little more life out of my cranker, not worth it. So I'll still have a dcdc on my auxiliary battery, and now I have a spare in case that dies.Why did you drop the DC DC charger?? Also, a winch solenoide may draw quite a bit of current and not be rated for continious operation. I'm not sold on the DC/DC unless you can afford a Lithium second battery .
Sorry, I haven't been on here in a while, and life has been getting in the way as usual... no photos unfortunately, but what i have ticked off the list are:Christmas update????
