I have this for my RV, no directions came but from what i see here and online, I use it on the negative post? I was going to put it on the positive? should I use negative if so why? thanks.... also disconnecting negative will stop battery from...

Most vehicles use a negative ground. In general, when servicing a battery, you should always disconnect the ground side first. That way, if your wrench slips and you hit part of the vehicle, you'll just be connecting the ground side of the battery to the ground of the vehicle, which causes no harm. If you slipped when loosening the positive post, and the ground was still connected, you could connect the positive terminal of the battery to the ground, which would cause arcing, or worse. So, because of that safety issue, people always disconnect the ground side first, and switches like this are usually placed on the ground side. Disconnecting either battery terminal will stop the battery from charging, since you no longer have a complete circuit through the battery. If you leave your RV plugged in constantly, and leave the battery connected continuously, be sure that your RV's battery charger is well regulated. (Although, perhaps that's why you wanted this switch in the first place-to prevent your charger from overcharging the RV battery.) Handy Bob's Blog, HandyBobSolar, has a big page of good information about RV battery charging. It's the page entitled "The RV Battery Charging Puzzle". I think I'm not allowed to insert links here, so you'll need to Google for it. Handy Bob says the biggest problem with typical RV converters is that some of them never get the batteries fully charged, even if left plugged in 24 hrs/day. Handy Bob goes on to suggest buying a large automotive battery charger, one that puts out 25 amps, and use that a few hours each day. That sounds like overcharging to me, but he's the authority here. Personally, I use a smart charger to top off my batteries, and I generally disconnect them from the vehicle before charging, and it's a low-amperage charger, as well. Mine's the 7 Amp NOCO Genius charger, and I think it's sufficient, but I'm only charging medium-sized batteries one at a time.

Are you using a grounding rod? The negative post should be wired to a grounding rod that you drive into the ground a few feet. The positive is hooked up to your wire and doesn't need to come back to the negative post. This is designed to have the wire charged and when something comes in contact with it it and the ground (dog,cow, horse) then it gives the shock. I'm not sure what your question is or how you have it set up. Mine works great.

I had my Son in Law to hook ours up, and as I understand it, it switches back and forth charging which ever battery has the lowest power. We are also using a straight deep cycle battery for house battery and a Rv starting/Deep Cycle on motor side. These things are the cats meow when you are on the water and drain your starting battery down. Lines Taut, GUY

This is a distribution block only for positive, it does not have a ground bus to hook the negative wires to. Hook the positive feed from the battery to the screw. Then hook the individual circuits to the spade connectors and plug in the appropriate fuse. If you are using this in an automobile, the negative can be hooked to any bare metal from the frame. If you are using this on a boat, you will probably have to run a wire to the negative terminal on the battery.

This block is to be used with a common ground system (I.e. The car body/frame is the ground). Connect 12v+ to the nut, then put fuses in block, then connect wire to spade terminals to your devices. The negative on your device connects to car frame. This all assumes this block is used in a car/ truck where battery has neg connected to ground. Boats utilize a ground block because they have a fiberglass hull that can't conduct electricity. They make fuse blocks specifically for those situations. This is not one of those blocks

The label must have changed. Mine had +/- Load. I hooked up the +from the P/S to the +, the - from P/S and LED light (load) both connect to the - on the switch. The + from the LED to the Load. My assumption would be Line/Negative/Load. You should contact the seller to be sure. Good luck!

clip on to battery positive to positive neg to neg make sure its in the sun and it will maintain your battery, I think mine is working really good.

Hi Shard, my initial assumption is that you do not have the connectors in the right place. The batteries are connected in series i.e. mine are 6volt batteries and I have 6 of them for a total of 36v. So the positive connectorhas to be on the 1st batteries positive terminal and the negative connector has to be on the negative terminal of the last battery. If you have it hooked up that way, one of the batteries might be bad. Bill

If I understand it correctly, it"s kind of like a "Miracle Charge" you would put on your motorcycle or antique car, but this one, "a microprocessor-controller that constantly monitors the RV battery status and automatically selects one of four charging modes: Boost Mode - (14.4) to quickly bring the battery to 90 percent of full charge, Normal Mode - (13.6) safely completes the charge, Storage Mode - (13.2), automatically activates after 30 hours of non-use or Desulfation Mode - (14.4), for 15 minutes every 21 hours to prevent battery stratification and sulfation (the leading cause of battery failure)." I think it monitors the batteries, locates the lo battery and re-routes power from another battery. It's not really a battery chargers, but more of a routing station. My RV has 5 batteries and sometime certain batteries use more power than others and this helps keep them all charged ith in the same range. That is what the hi-lighted section refers to. Mine has worked very well. Dont buy the cae they try to sell with it. Its plastic and will disappear with a good kick. I used a chain of a cable with a lock. I hope this helps, but I could be totalyy wrong.

Its either. I believe it is so you can DC out to another product. Or, apply another battery as stated below. The instructions do not discuss the issue.

Sorry- looked at my controller and the positive is shared. Hook the negative from each panel to separate neg (-) terminals. Both positives share one terminal.

This unit provides both a negative and positive post on the face of the unit itself. Each is equipped with a thumb-screw nut and you can connect your wires directly to these posts. You can run these wires to whatever you are powering directly or you can put alligator clips at the ends in order to easily change out and use different 12 volt equipment.

On a small 12V incandescent light, polarity is not critical (positive and negative) to make it light, what can become important in a marine environment is corrosion from electrolysis. A good practice is to disconnect the battery when laying up the boat for any length of time.

I tried 15+ minutes, usually 2 AA or 2 AAA batteries. Not sure polarity matters, it just reverses rotation direction. I tried 5V but it makes it really hot.

You should be able to wire together all positive an all negative and just connect one + and one - to the battery. The current draw is fairly low so it should be no problem.

The meter supply with polarity connector, black and red wire, which represent minus and plus. The unit does not work at all if change polarity.i do not know what will happen if connect minus 5 v and plus 5 v. without ground. I assume it will not work or just show something wrong. Also, I take a look on surface mount parts and see that red wire via connector goes to diode. You may order this little thing just for few $ and blew up it under your desire in many different ways.

2 posts in middle are for positive/negative DC Input. The two outside posts are for positive/negative DC output to motor. Switch just reverses polarity on those 2 posts.
