How do you determine polarity? The output is not marked.

If you set the unit on the table (orented so you can read the display). The positive terminals are perpendicular to the table surface, nearest the buttons.

It uses deans connectors which determine the polarity. Search images of deans connectors.

refer to http://eastbay-rc.blogspot.com/2010/08/connector-mania-t-connectors-aka-deans.html - red is positive, the pin goes "across" the connector. Negative pin goes "along" the connector. This is standard for all LiPo batteries, visit your local RC hobby store to see it in person.

the wire with the dean connector that is included is color coded red/black for the polarity. output is the load dean socket. source is the input dean socket. it's clearly labeled in the watt meter case where you plug in the dean connector.

The polarity of the T connectors is standard -- the top bar of the T is positive and the post is negative. The labels on the diagram in the instructions are misleading since they are opposite to the orientation of the T sockets.

The output is a standard Dean's plug. So the slot closest to the white balance plug outlet is the positive lead.

My unit uses a "T" (commonly referred to as a 'Deans') connector and the polarity convention is that the top of the 'T' is the positive pole and the vertical leg is the negative pole.

Sorry, but I don't remember. Mine was used with a 12v DC converter for a light strip, so polarity is a definite concern

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

The face of the meter has a diagram of what the various lighting scenarios mean. If the left light is out and the right one is lit you have correct polarity. If the left light is lit and the right one is out you have reverse polarity. If both lights are lit the connection is open neutral and if no lights are lit the connection is open ground.

Yes A negative sign (-) will display on the meter when checking DC voltage and the meter leads are incorrectly placed on the voltage source. When the meter leads are reversed, then the negative sign will not appear.

Mine was clearly marked. From left to right (looking at terminal end of board:Gnd ( battery negative)motor (load) negative -motor (load) posative +Battery posativeHope this helps

Yes.....but be CAREFUL that you keep the polarity correct....(+ to +) (- to -) if you want to know how to know which is witch ......The plug with the shinny end..(the tip) the shinny part, the outside is (-) the inside is (+) .....I hope this helps...don't be afraid to ask....JIM

The output has simple +/- terminals, so you need something else to switch the polarity outside of the unit.

I'm not sure what the polarity is but there is no option to reverse it on this device.

Look at the + and - on your battery and line up the pins it doesn't matter which ones the charger automatically recognizes the polarity.

Take a digital Volt meter and it will tell you if it is positive of negative.Don

The manual basically reads: Wires that your attaching to the battery are crossed (AKA polarity)

Check the polarization of the wires. There are only 2 wires but they must be in the correct polarization

If right light is red, wiring is correct. If Left is red, it has reverse polarity. If Both are red, there is an open neutral, and if both are white, it has an open ground. I use it in my 5th wheel to check wiring at campgrounds. It has instructions right on the unit.

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.

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.

Sorry I do not remember the polarity only that it is the same as the battery pack that it is to replace and it works fine in that application.
