what is the polarity of the controller. I have read specs on some controllers from China that were positive ground.

It is a negative ground. Of it wasn't any ways, you could reverse the wiring at the controller.

Polarity is embossed on the ceramic substrate with traditional symbols of positive and negative. If you can't locate, use s multi meter as it is a diode and only passes current from negative to positive

Not positive. Both of mine did not work & where trashed shortly after bought. China I think.

It's not reversed polarity. If the polarity is reversed the 63001 is completed non-responsive. I have the same unit. It is displaying -1, but otherwise appears to be functioning normally

Polarity should not be an issue. Also these are probably a little large for an instrument cluster.Check for cross reference guide for what you have now.

11~24VAC/VDC(Non-polarity) - More information and spec sheets at: http://www.seco-larm.com/E960LRb.htm

It is wired backwards. verify the led's are attached to the led side of the controller. Also verify polarity. The led strip will blink id polarity is reversed.

This controller has a max rated input of 45 watts. You run the risk of damaging the controller

The center post is NEGATIVE, the outer shell is POSITIVE. This is opposite of what many common connectors for power supplies have. You need to look on the Casio specifications for the AD-5. Also, there is a small diagram on the plastic case of my CT-700, where the AD-5 plugs into the keyboard, that shows this polarity requirement. Jay Daugherty is incorrect.

Just a note these controllers wont do zip when the input amps are below 15. The two Panels most likely will not enough to fire is up. DM 145 Watt panel crank out on;y 7.7 each amps on a good day. I Bought this CC and had an electrician (Who Wasnt Cheep) confirm this about the CC. Dont get me wrone thee CC will work but you will need to put three 124 watt panels on it. If you want a CC controller that will do the two with ease. Check out the HF CC 30 amp 500 watt CC by thunderbolt. Its about the same amout of cash on amazon. Good luck on your decision.PS If you go with this one the manual stinks. Learn chinese Just a note these controllers wont do zip when the input amps are below 15.

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

Polarity should not be an issue. You can come out of the power supply only one way with the main wire, then into this "jumper" and out. Noting colors (e.g. red to red, ensure they match. If not cut and splicing will be required. Excellent product.

I was emailed by amazon and asked to reply to your question. Bottom line is the ones I got are only two wire (brown and green ) and polarity does not matter with them. You are safe testing by randomly touching the wires to the battery leads to find out what will work.

It all depends on the type of DC motor you use.If the motor will run directly from DC power source, such as a small battery, in both directions (by reversing + and -) then it will also work in both directions with controller. I am using this controller with dad switch. HOWEVER THE SWITCH TO CHANG POLARITY NEEDS TO BE PLACED BETWEEN CONTROLLER OUTPUT AND MOTOR. IT WILL MOST LIKELY NOT WORK IF DPDT SWITCH IS PLACED BETWEEN POWER SOURCE AND CONTROLLER. I MYSELF DID FIND A DC MOTOR THAT THANKS WORKS VERY WELL.I CAN CHANGE THE DIRECTION OF SHAFT WITH DPDT SWITCH AND VERY THE SPEED IN EITHER DIRECTION WITH THE CONTROLER. I HOPE THIS HELPS.

the controller pictured has reverse current protection built in. So the short answer is YES. However, the real question is how reliable is the controller.

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.

Yes, for a parallel connection it's positive to positive and negative to negative and then on to the charge controller.
