I see what you are saying.. The relay you are speaking need a sensor to detect current presence from the alternator. Then it links both battery Is it that? The alternator is internally regulated, so you don't have to worry about that.
The problem with "cheap" isolators is they tend to lose up to a volt to each side, and generate significant heat. Someone makes a really nice isolator that has internal switching so there is no voltage loss when charging, and complete isolation too. What loads are you trying to separate? That's all. The amp could be W max. I found Hell Roaring to be a good site and they have a good rep.
Mike there is very helpful and answers emails. They might have what you need. Keep it simple. Just use a snow plow pump relay. Cheap, effective, no voltage drop. Only need a 10 charge wire for your setup. Or, if you're like me, you can leave your headlights on overnight, and jump start yourself. I know a simple relay can do the job I think I'll go with a separator. In fact, this is the same as a relay but it is smart!
SurePower sells them. I asked them why and couldn't get precision to this answer. The guy wasn't sure so I try to avoid thing that aren't sure. I know they sell good products. It just doesn't do what I want. I was discussing this dilemma with a friend of mine at the 4wd club and he told me that he was a plumber and welding was part of his job.
He also owns a MIG welder and metal cutting circular saw. So we arranged to get together and build it up. So on the day, I provided the design and he provided the know-how and we put together a frame that will be the last thing left of my car when they drop a bomb on it. Once the frame was all done up, it was time to install it into the car. This involved drilling some holes at appropriate places and attaching it with 8mm bolts and nylock nuts.
I then put the battery in place and noticed that the upper rear corner of the battery touched the outer shell of the car. So leaving it like that would eventually bulge the body work outwards. To fix this, I needed to lean the battery inwards a little so I cut come pieces off and old towel and put them into the back of the battery bracket.
The battery now leans inwards slightly and is about 8mm off the bodywork so hopefully, that will be OK. Then there would be plenty of room for it all to fit. In addition to wiring up an Anderson plug on the tow bar, I also wired in a small fuse box. From the fuse box I have then connected 3 12v power sockets in the boot. Drilling through the trim and cutting large holes in it to put the 12v sockets into was exciting. Not difficult, but there was a lot of checking and rechecking to make sure that the back of the sockets would fit once the trim went back on.
It took a bit of courage to commit to it. At the moment the UHF is wired to my cranking battery and turns on and off with the ignition. Wow, it seems like an awful lot of trouble for just 3 sockets in my boot… But once the camper comes along and I get around to finishing off my other plans, then there will be more.
When I put it back in again, I resprayed the area where my earth wire was with my anti-rust spray and carried on installing. When it was all done, I turned the engine on expecting the RedArc to light up as it always had before. Nothing… Oh oh… What have I done…. When I pulled it off, I noticed that the anti-rust spray paint had got down between my earth cable and the body work.
So I got out my grinding drill bit and ground the paint back off again. This time, when I turned the engine on, the RedArc behaved as it should and the whole system started working. Lesson 2: There is an awful lot of room behind the trim in the boot area.
Lesson 3: Take your time and do it right. Make sure you do a proper job of it from the start. How long would it last for, and how long it'd take to…. Since then, I have been contacted by a representative of Ark…. This is where my problem begins. Can you put mud tires on a 2WD truck? What are mud tires, and what do they do? This easy battery upgrade sets Project Bedrock up to handle any electrical need we might encounter in the field. But it happens. Whatever the reason, it does make it easy to double-up the batteries.
