Works perfect
People have issues with this not working, they are obviously hooking it up wrong. You need to find the series in which your batteries are running. Easiest way on a golf cart is to look at which wires go from your battery pack to your run/tow box. Those wires will be your positive and negative. You can always test with a volt meter. You will want to attach positive to positive battery terminal 1 in the series and your negative at the end of the series, if you don’t do that you will not get proper reading and possibly battery meter failure. Then connect C or common to the on position post of your key switch, if you don’t do that the meter will keep scanning and give false reading or no reading at all. Sounds confusing, but I’m sure YouTube has videos on battery series and hooking a meter up.

Works as described.
Works as described. Time will tell on longevity. Lights are bright. To bright in the dark, hard to determine what bar is lit. Note: people are complaining that the meter doesn’t read correct while charging. My oem meter does the same as it needs to be refreshed. My club car has a transport toggle switch. Just a click off and on and it refreshes the meter, no need to unplug the negative wire to refresh as others mentioned.

Less than 8 months later and the gauge is broken
My grandfather installed the gauge and it hasn’t worked well at all. I used the cart about 2 months after installing the gauge and the gauge said batteries were full and by the time I rode around my neighborhood 1x my cart ran out of power and the gauge didn’t tell me it was close to being out. In fact told me the cart was 80% full. I bought brand new batteries and got in the cart 2 weeks ago and the cart said batteries were only halfway charged. I got the electric meter out and all 4 batteries were at 12v (48v) cart but the gauge said is only halfway charged still. The cart has been fully charged the last 3 times I have used the cart but still only says halfway charged and doesn’t go down when I use the cart and go below halfway. The gauge doesn’t work well at all

It works… sorta
This is a nice looking power meter and is easy enough to wire. Ground to ground, positive to positive and to the key switch. It turns on and seems to provide a close level of power availability… until you go to recharge your cart. When the cart is fully charged and you turn everything on, the meter will show where it was last positioned. Meaning if you drew down to 50% power and the. Recharge, it will show only 50% when the cart is actually fully charged. Another commenter stated if you disconnect the ground and reconnect it resets. I did this and indeed it does reset, but this seems somewhat cumbersome to do every time after a charge. I ordered another unit to confirm this is indeed not a “me” problem but rather a product issue.
