One answer says there is a positive and a negative and another says there are no Negative (ground) terminals. Is there a neg and pos?

There are both negative and positive terminals, in the picture the positive it next to the line of fuses and the negative terminals are all in the lower right. You connect the positive load wires on the lugs to the outside of the fuse block.

The set of ground tabs is your Negative (ground). Normally, you'd directly connect the set of ground tabs to your vehicle chassis ground. Each fuse's fast-on (0.250") connector is Positive. You can use the ground tabs on this fuse block if needed, depending on how you're wiring everything.

All points on a bus bar are electrically from a single point. So if you wire one point to the negative terminal, then all posts are negative. If you wire one post to Positive, then all posts are positive. You would never wire both the positive and negative together on the same bus bar or you will have a firery short circuit.

There is two stray wires for positive and negative. You can connect it to batteries. Connect it to a 12 volt source i.e. inside cab lights.

Negative, yet there is an input receptacle with NO SPECS as to polarity and voltage needed, as well a missing current spec needed when multiple items are connected. Closer inspection of item shows no specs ON the item either, but it appears that an area below the receptacle has been sanded off, as if the specs were removed, as was the model info. Weird.. Inspection was done with lighted magnifier I used at NASA to inspect pins. sort of like owning a 7-stall barn that will only hold 4 horses at best ;-)

Mine has three terminals, + - L. "+" is the positive source to the battery. "-" is the negative to the battery and negative to the load. "L" is the positive to the load. If yours is different, good luck.

Sounds like they are mismarked. The polarity cannot change through the connector. The two + now become 1 +. The two - now become one -. Once you have the 2 panels connected in parallel, use a voltmeter to check the polarities to prove it to yourself.

Usually you use the two outside terminals or whichever ones are marked + and -.Polarity does not seem to matter to the charger.

In most cases the red wire is the positive and the other corresponds to the negative pole. You can try in any case the product has a protection system when connected inversely.

yes it's true, it has no polarity on both terminals. either ways of connections work properly.

Yeah. There's one wire for a positive signal and one wire for a negative signal attached to each other.

The red terminal is POSITIVE and the black one is NEGATIVE. I do not understand F1 and F2, as it may be specific to your schematic or circuit.

There are two tabs on the battery, one red and one black, The red is positive, the black is negative. The wires are attached to these terminals as appropriate. As a word of warning DO NOT LET THESE BATTERIES GO DEAD. I had two and left them uncharged - both went dead with no hope of recovery

They are just different ways of connecting, one by screw block and one from a power adapter plug. It depends on what you are going to power it from. The negative screw block terminal is very useful as well to connect the grounds of the source signals and the power adapter so you have a common ground.

There is no positive/negative wire. One end goes into the outlet and the other goes into the device.

They have a common negative or ground. The positive side is switched through the regulator

Normally you put the disconnect on the positive terminal in a negative ground vehicle. However, after checking throughly through the system on on of my vehicles I couldn't get it to work. So I put it on the negative post just making sure there no other connections. Use an ohm meter to tell you if it's OK.

Yes. Just do not ground the gold terminal. Gold terminal - Ground Middle terminal - Load Other terminal - Positive (Battery)
