SOURCE: completlly stop working after wrong polarity lead been plugged In

one of the first things that go are is the protection diode coming off the + input. Then a fuse and so on. Surface mount fuses are light in color (usially green with white text). Attempt to bypass these components with a small wire or paperclip. Once you follow the lead from positive input you will run into a black rectangular block about the size of a grain of rice with 3 leads. That will be your voltage regulator. Its set at the correct voltage, and since you already have a power supply with a set voltage, then you dont need it. Its also the first thing that blows when you switch polaritys. (voltage regulators have 3 pins - input output and ground) when you switch polaritys that ground becomes the "input" and ..... go to all http://www.alldatasheet.com/ and type in the text you see on that component. It will then identify the component and list its voltage output and at which pin.  Apply set voltage to lead and ... pray? 

Best of luck.

SOURCE: Zivan NG3 battery charger diagrams

Hi,
your NG3 should have been preprogrammed for the type of batteries you are charging. The NG3 has the 3 wires from the power cord. Here is what I have done:
Brown from charger goes to black wire
Blue goes to white wire
yellow green goes to green ground.

I'm charging my battery on my rv new. Artery but it was ran down because my break switch was bad and the light stayed on my new cen-tech charger light stays green and I hear a clicking


Disconnect any wiring to the battery. Connect only the charger. Insure you have the charger connected to the proper polarity.

Does it continue to click? Does it not charge? If it won't charge for you, pull the battery and take it to a friendly service station or auto parts store that can test, and or charge it for you. It could be you discharged the battery all the way and damaged it. The normal safe zone is to never discharge below 50%. They might have to attempt a charge that takes up to 45 minutes. If the battery is over a couple years old I would opt to just replace it. I would never trust it and end up getting stranded somewhere.

Battery state light stays on & discharges battery


something not right here with the question/request---""unplugging the 230 volt charger"????--I don't know of a 230 volt charger---unless this is in Europe---a 120 volt charger---in USA-- but I'll try this---a LED light does not use enough electricity to discharge a battery over night--- do you have another function on this unit such as a compressor or lights--something that maybe on???---another thought is that the battery has failed causing this malfunction----has this been wet/underwater---a malfunction with a diode in the electronics may cause the charger to try and charge the battery via ac and cook the battery as well as the circuit board---this is a real issue here---I'm not getting enough info to give an intelligent answer---i need to know if anything has happen what has happened before and up to this point when this issue started---I don't know what happens if when using these units if you connect to (jump start) battery with reverse polarity--if it bows a fuse or cooks the unit---sorry I can't be more helpful

Golf battery polarity


reversed polarity,check fuses. check the system for burnt wires also !
Always hook up your battery terminals correctly, as the alternator may be damaged if the battery is hooked up backward. jump start car, if it will. there should be at least 13.7 to 14.2 volts at battery posts while its running. if alternator is ok.

I had my wheel chair in storage for about an year, I have attempted to charge but when I disconnect the joy stick blinks yellow for low battery...How do I determine if both batteries are bad? If so do I...


Hi.Sounds like your batteries have sulphated plates, this happens when they sit for too long without being used. Your machine is a 24 volt system, so it needs both batteries to be working.You might be able to get a bit more life out of the batteries.
Try removing both batteries from the machine and connecting a light bulb across each battery and discharging them until they are flat.
Then using a 12 volt charger, ( not the charger for the machine, which is a 24 volt charger ), charge the 2 batteries in parallel. Sometimes it helps to charge them up the wrong way for a few hours, then discharge them again with the light bulbs. After this charge them again in parallel with the 12 volt charger, this time the correct polarity, a leave on charge for 12 hours.
You might have to repeat the charge, discharge cycle a few times.
The batteries will accept a charge after a bit of this, but they might not be as good as new batteries.
If you are unsure how to do this, get some help from someone who can do the work safely.
Good luck. Neil.

Ryobi charger model # 140295003 has a red and yellow light. When charging red light is on what does the yellow light mean? Also how long should the battery be left in the charger?


Completely wrong. Quoting from the user's manual:

"The charge indicator light (LED), located on the charg- ing stand, will light up red and glow when the char- ger is properly connected to power supply. This light indicates the charger is operating properly. It will remain on until battery pack is removed from charging stand or charger is disconnected from power supply.

After normal usage, 3 hours or less of charging time is required to fully recharge battery pack.

If both red and orange LED indicators glow, the battery pack is deeply or completely discharged, and 6 hours or longer of charging time is required to fully recharge battery pack.

Note: If charger does not charge battery pack or orange LED continues to glow after more than 30 minutes of charging, return battery pack and charging assembly to your nearest Ryobi Authorized Service Center for electrical check."

So to summarize: red = charging. orange (yellow) = fully discharged battery. orange after 30 minutes - bad battery or bad charger.

I really don't have any idea as to what you're talking about here other than a battery and maybe a charger. Seems as if you're saying that you have a 12 volt 1.5 amp automatic battery charger connected to a 12 volt, 8.5amph battery but the red light on your charger is blinking. The blinking red light indicates that the charger is not seeing a proper connection such as crossed polarity connection or simply a poor connection. You say that the battery voltage has dropped from 12.5 volts to 9.1 volts with the charger connected. If this is the case, the battery is badly discharged and the charger is not charging the battery for some reason. The charger may be bad but check the connections to make certain they are correct and good. If they are, I'd replace the charger.

Good luck

InvaMed Sovereign Mobility Scooter Model S888NR battery charger red light flashing to indicate fault. I have a multimeter and want to know how to test the charger. I need a wiring diagram and to identify...


Hi. Its easy to identify the pins out. Put the probes into the socket on the scooter to read the polarity. the two terminals on opposite sides will be the positive and negative battery supply. The pin to one side is to disable the scooter when the charger is connected. This terminal is normally connected to negative when the charger socket is in place.
Most faults like this are caused by a broken wire in the charger plug orv by a faulty connection in the scooter. Sometimes the charger socket is faulty, check for heat damage or melted plastic.
Check the battery connectors. Good luck. Neil.

Flashing red light on the Kensington wireless mouse base


I still have the manual for my mouse.  Model number 64321.
When this mouse was manufactured it used NiCad batteries which developed a memory much more than the newer batteries.  The older NiCad batteries needed to be conditioned occasionally so Kensington provided a way to do that with the charging base. 
The red light is for indicating discharge status of NiCad batteries.
The red light will flash quickly when you press the battery discharge button on the bottom of the base.  This indicates that you now have 5 seconds to place the mouse in the charging base for battery discharge.
The red light will flash flash more slowly when the battery is being discharged.
After the battery is fully discharged, the base will then charge the batteries.
It should be noted that very few manufacturers of products that utilized NiCad batteries provided a "battery conditioning" feature.  Kensington was unique in this regard.  Battery conditioning allowed NiCad batteries to have a longer useful life.

Now maybe you can help me....  I lost my power supply that plugs into the USB connector.  If you have yours, can you tell me what the output voltage is and what the polarity is of the inner pin.  This will be marked right on the power supply base.  
I plan to just get a generic power supply from Radio Shack, but I need the voltage value and polarity.  Until then, I can still use the mouse, but it won't charge.  FOr now, I'm just using standard AAA batteries.
Thanks.

Chocolate wont turn on, help?!


Hello guitar girl,

The battery is probably dead. Every battery has something known as recharge-cycle limit(number of times it can charge and discharge). Replacing the battery will most likely resolve this issue as the screen turning on when connected to an external power supply indicates that there is nothing wrong with the charging port.

Sai.

next to the jack on the camcorder it should have a diagram that shows polarity (a + and - sign) for the plug, the tip should be one sign and barrel or outside of the plug should show the other polarity. you have to have your plug with the correct polarity, and you have to have the correct voltage( it should say 9v or 12v or something like that) and the supply you use should be as high or higher of a current rateing as recommended in your users manual or printed on the supple that came with it.
