Meter installed quickly and easily. However, the batteries are fully charged, and the meter is alternating between orange and red. Suggestions?

not wired correctlymake sure to test the polarity and voltage of the post that you attached it toIf not the full voltage of 36 or 48 whatever your cart is it will give that orange/red indicatorIf no voltage meter available just start going to different battery post

Yes. Mine did the same thing. I tested the batterie and found the two in the front weren't as strong as the ones in the back. I rotated them front to back and charged them and the gauge has worked every since. Hope this works for you.

The meter is faulty, mine shows full most of the time, when the batteries run out the meter shows its over half full. Return it and try a different brand.

check for a full 48 volts at the terminals that connect to the meter with a voltmeter. A bad ground or excessive wire resistance will fool the meter into giving a lower than normal reading. Or the meter is defective. A digital voltmeter will confirm the actual battery pack voltage.

Check the batteries systematically in different combinations per previous note

I have the exactly the same question. The charging light of mine stays red after an overnight charging. That contradicts to what the manual said: "orange while charging, green when it is fully charged". It looks like it is a common problem so that mine is not defective, then I do not need to return it.

How did you try to measure 24 volts? If you used 2 twelve volt batteries in series make sure they were connected one + lead to the other - lead. Or try to measure 3 nine volt batteries snapped together. You should get 27 volts. I think there is a calibration pot on the back of the meter. It is very small and you will need a jewelers screwdriver to adjust it. Make sure the red lead goes to the + termingal of the battery. Try again and let me know. You could have a bad batch of meters. Mine worked very will on my power supply that goes up to 27 volts. One last thing...are the 24 volt batteries you are measuring good batteries? The meter might be telling you that they are not. Hope this was useful. Also be aware that all meters have a percentage of error. Some are + - .1% + - .01%. No matter how expensive the meter it will have error tho very small. The smaller the error, the larger the price. These cheap but beautiful meters are good enough for battery monitoring. I wouldnt use them to build a computer power supply.

This didn't happen for me. It could either be a faulty meter, or it is getting 0.0 volts.

I noticed it doing this on my 75AH battery. But on my 35AH battery it does not do this, or it hasn't yet. I think it has to do with the battery size confusing the voltage reading. Batteries are still tricky to master. It's better that it's cautious during charging rather than brute forcing the battery into oblivion is my guess as to why it's quirky. What size battery are you charging? There is a range specified in the owner manual. I think 75AH is the upper limit. Maybe that's why it's doing that on the larger battery.

I have the same problem. I can sometimes adjust the transmitter power to get around it. It's a good case of "you get what you pay for." It's a cheap meter--cheaply made.

Assuming that the meter worked properly in the past, I would make sure that the wiring connections to the meter are clean and secure. The possibility of corrosion increases with time. If this issue has come on slowly, corrosion may well be the culprit. Good luck.

I purchased a BAT-250, it is red and the meter display is located at the top not side of the tester. Mine works great and would highly recommend it. As J.Qualey mentioned with the BAT-250 it has a groove to better hold and keep the contact points of the batteries in line for testing.

After my last response I remembered how it was wired. You will need to read voltage at the battery. On the back of the meter is a plug with a 2 wire pigtail. The pig tail wires are red and black. The black wire goes to the negative post on the battery. The red wire goes to the positive post on the battery and the battery voltage will light up and you can read it all the time. The problem wiring it this way it is always on and can drain the battery of its voltage over time. The other way is wire the meter through an off and on switch. The black still goes to the negative battery terminal but you need to bring a red wire from the positive side of the switch and then on the wire coming out of the switch take that wire and connect it to the positive battery post. When you flip the switch off and on the meter will register. If you are not sure when the switch is on or off. A multimeter can be used. Set to ohms put one lead on one switch connector and the other lead on the other switch connector. One side will be able to read ohms and the other side will not as you flip the switch back and forth. The side that reads ohms goes to the positive terminal. Hope this all helps.

On my unit the light is red, and it starts flashing red when I place a drained battery into it for charging. Once the battery is charged it turns green and stays green until I remove the battery to use it.

If it is not working properly, it will not fix on its own. If you followed the installation instructions, you would have hooked one wire to the positive+ terminal on one of the batteries on one side of the cart, and another wire to the negative- terminal on a battery on the opposite side of the cart. Then, there is another wire that you hook up to the ignition key switch so that the battery meter doesn't stay on all the time and will only come on when the key is turned on. I had to use trial and error to determine which wire was correct on hooking that wire up. As the batteries start to go down, the green bar will move from right (fully charged) to left (empty). After the bar goes to half way, it will not be green and will change to amber color. Then it will turn red when there are about two bars left. You should never let your batteries get below half way before recharging. These batteries should always stay on charge when not in use. When I initially installed this meter on my golf cart, I noticed that the meter would not go all the way to full. I later discovered why, because my batteries were old and would no longer take a good charge. Once I bought new batteries, it shows full after it has been charging. I would recommend that you follow the instructions and make sure you are hooking up the correct wire to the right battery terminals and the igntion key switch wire properly. I would highly doubt that the meter is defective, it is probably more likely that you have a wire hooked up wrong. Hope this helps.

I think it's when you turn the power on and the light is red instead of green. Just happened to me. I changed the batteries and the light turned green.

I am not sure why it does it, but mine does it occasionally also. One thing you can check is to see what Amp hour you have it set for, It seems that when mine shows that I have had the Ah set wrong and it is showing that because I have had it set to a higher Ah battery than what I actually had. The battery will only take so many amps before the resistance gets too high and charge shuts off. If you have a 100 Ah batter and have the meter set to 200 Ah, The meter will show half full when the battery is full and the charge shuts off or goes into float mode from the controller. That is where I would look first. Make sure that you have the meter set right with the battery you have and then if it still shows 60%SOC you may have a bad one. But After I changed my settings, the meter seems to be reading correctly. It has actually gone to 100% Hope that works for you!

I just checked, since I had unplugged the lights after Halloween where I had selected orange (red and green lights are lit and it looks kind of orangey from a distance). When I plugged it in, it was still orange as I had selected last time. I hope this helps.

Sorry Calvin, I think this a great meter, however, I only use it to check the voltage on my AA and AAA batteries and rechargeable batteries from Amazon..... Works Great ! Phil Pauls Valley, Oklahoma

The way to check it with a meter, is for continuity, not voltage. Put your meter on OHMS and check between the battery neg post and where the cable attached. You will see it reads "Open" when the knob is turned clockwise to loosen it. When tightened the connection is completed and you will have continuity "0". Proven that no electricity will flow with the knob loosened.

Mine has RED indicator lights also. I haven't used it often but it seems to work fine.
