Just received two of these and neither works when attached to 9 Volt battery (polarity hook-up is correct) and battery voltage is 9V Any suggestions?

If battery is at least 5 volts and gauge does not respond when connected then gauge is bad. My recollection is, there is nothing to adjust or set up on these. Just the two wires.Max 30V so don't connect to wall outlet! (duh, these are DC anyway).I'd test by finger-pressing the stripped ends of the leads directly on the tips of the 9V battery.A regular 12V car battery would also have contacts available for testing, in most cars.

Ours worked fine on our 12V solar home battery bank. Maybe it is an issue of having a higher voltage.

I use two regularly hooked up to my car's electrical system. They've displayed without fail even down below 11 volts. I'm confident that if working properly they will work down to 4.5V as specified by maker/seller.

Try higher than 12vdc. I use it on a 24vdc system, and have not tested until your message and it works OK.

Sounds like a loose connection. I would take it back to where you purchased it and ask for another, if they wont help, contact the company, and see if they will exchange it for you. You might first try making a good tight connection between the battery terminals and the battery by slightly bending the terminals towards the battery for a tighter fit.

Heyy, try using just a regular battery. Positive is red or with a code written on it and negative is the solid black. I tested all before installing and only one didn't work. Hope this helps :)

I's surprised that you got a shock from a 9-volt system. Could the shock have been a static discharge? In any event, remove batteries & unplug from wall. Wait a minute, then plug in the cord and then follow Owner Manual directions for a new setup. If this doesn't work, then you've probably blown a chip and need to return the unit for a warranty repair.

Please check your 9Volt battery to make sure it's not dead or week. I have not used mine yet I will this weekend. My email is nadroy00@att.net drop me an email in the afternoon CST and I will let you know how my unit works.

Make sure the wiring polarity is correct... I had mine reversed by accident at first, and it didn't work (plus the power wire almost immediately heated up).

Check to make sure the battery contacts aren't bent. Double check to make sure the new battery is actually good and that it doesn't have one of those clear insulating stickers on it. Maybe try a different new battery if you don't have a tester. We keep a spare pendent, just in case. They're quite inexpensive.

Mine worked fine. Suggest this could just be a faulty unit and request refund or replacement. I presume you have inserted batteries in correct order

I'm guessing the plug in your connector is round, this one is oval with 8 holes connection. If oval and connection work, I don't see, why not Word of caution! if you don't unplug from battery when charging it will burn out circuit board. Mine did!! sorry couldn't be more help! charging

This machine requires a 6V adapter. Sounds like the adapter you are using may be the wrong polarity (center contact POSITIVE, outer contact NEGATIVE) or the excessive voltage may have damaged some of the electronic components. Will it still work on battery power?

You need to make sure you use it's cable like brian4698 mentioned. It is not the standard polarity, so if you use any old cable that fits, you've reversed the polarity and can do damage to the unit.

I would send it back if you can. I purchased same item and one battery will not charge and the other battery was dead out of the box and Amazon doesn't pay any attention to these messages or I would have heard from them from a previous message.

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.

I use a generic one, with interchangeable connection pins and variable voltage (but fixed 3A). Set it to 9V, center pin positive connection, and you're ready to go. I'm pretty sure you can find one here.

Read the instructions and make sure everything is being hooked up properly. If that is not working I would try a new battery or send it and exchange it. I have had zero problems with mine so far. I hope this helps.

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

Thought of something else. Make sure your power adapter is set to the correct polarity + -, mine is set at +
