  1. If the green light on golf cart is flashing does that mean it’s charging

    1. Yep….

  2. If the fault indicator is flashing twice between pause is the unit still charging the batteries?

    1. David – Thanks for the question. Sorry it does not sound like it is. best way to determine is check the battery bank with a DVM – “Digital Volt Meter”, with charger not hooked up, then hook up charger and see if the voltage is different. If higher then you know it is charging if not will most likely need to be replaced.

      Or if the batteries are so dead – no voltage at all – that is what the charger is telling you and will not kick on unless it can sense voltage. It is a safety feature designed to avoid electrocution. All new style chargers will require sensing voltage before they will apply amperage.


  3. I have the QuiQ charger on my golf cart. After fully charging the batteries, will the charger ac t as a trickle charger and if so, for how long?

    1. Tom – Thanks for the inquiry. No sir the charger will just go into a float state.

  4. My quiq 912-48xx is acting strange. When I plug it in to my 48v E Z golf cart it only registers 6 amber solid ammeter and AC On amber solid. It NEVER CHANGES. I CHECKED EACH 6 BATTERIES and they each register 8+. Can you advise?

    1. Tony – Thanks for the question. It sounds like it is doing its thing. Has good AC power and is making a connection if displaying 6 bars… Which means it is working ( wide open – max output ), how long did you leave plugged in? If new batteries they will suck up electricity for a long time , as the lead needs to be cured and the plates energized. A process that does not happen at the manufacturer. Typically it will run for 10-12hrs even new batteries. Though the charger should eventually fall off the 6 bars, and work its way down 5, 4, 3, 2, 1, green light full charge. They will be bubbling away and off gas more so when new then after cured… average takes 20-25 charge cycles to really cure the lead. I always recommend charging a new lead acid battery 100% prior to putting into service.

      If not new batteries and are actually quite old might be issue as well. These chargers look for voltage achieved before they shut off. So if the battery bank as a whole is never reaching thr voltage it is programmed to look for it will keep charging until they timeout and throw a fault code light. ( 12hrs). – OR – If the charger has just developed this issue, might need to be replaced as sounds like an internal fault.

      Power On…

  5. Hey Pete,
    I’m perplexed over my 2018 Delta Q Ezgo 36V Charger, Model # 913-3600-E1; Which is fairly easy for me. Hadn’t used either the golf cart or charger in about a year. Got new batteries and got the cart running good. Got time to put her on charge and the indicator lights up amber on level 5 of ammeter, amber light on charge, green light on charge, amber on AC, and red on fault. Nothing blinking. I have tried everything, It doesn’t change no matter if i unplug or charge all night. It is hung up and it doesn’t even get warm.
    I hope you may help. It cost a lot brand new and has been kept inside and in immaculate shape. Thanks

  6. I have a 48v EZ Go golf cart. Batteries are 2.5 years old. We were away from the golf cart for a few months and we mistakenly forgot to plug in the charger. So the batteries were dead. I used a conventional charger to put enough in the batteries so the QuiQ charger would sense some voltage and complete the charge.

    After being plugged in overnight, the charger timed out. I checked the batteries and they were all slightly over 8v. I reset the charger and plugged it back in. Now the charger is still in 6 bars bulk charging. The light for 80% charge is on. Is the charger operating correctly. I thought at 80% it would go to next phase and not bulk charge. Is it over charging?

  7. Hello I just purchased a 2010 Polaris golf cart with the Qui Q charger. My question is the same as Tony Metro. The charger shows solid light on 6 ammeter and AC on. How long should I leave it on charge before the green light comes on for complete charge? The batteries are 1 1/2 years old. so pretty new. do I have to wait for it to cycle through all the bars? I’m not familiar with these chargers so I just want to be sure I understand how to read the light indicators. I have downloaded the manuel. thanks,

  8. Good afternoon, My 913 48 V charger has stopped charging the EZGO cart. I originally thought it was due to low battery voltage because when I parked the cart the red light flashed twice and paused which is the indicator for low voltage. So I charged the 8 V batteries up and there is now 49.4 V across the bank. The charger is still flashing two red and pause then two red. The charger does the exact same thing if the output cable is attached to the cart or not. Is there a fuse in the charge circuit on the golf cart or is there something else wrong? Is there a way to check the charger out put via the three prong connector?

    Thanks for your help.

  9. I have the 913-4810-E3B charger. It has started showing two red lights flashing on the bottom. I replaced the batteries and they are up to 50 volts when installed. The charger used to go through a sequence of lights then settle in one place and charge but this is not happening. Any suggestions?

  10. I have the 48V QuiQ charger, it appears you can’t leave it on all the time, when charging is finished we unplug the batteries but leave charger on, then it goes into fault mode and you have to reset it when you come back later to recharge the batteries

  11. Can you leave the QuiQ charger on without the batteries being connected

  12. How do I know when my golf cart is fully charged

  13. Model: 913-4810-E3B

Please confirm receipt of this message if possible and advise if you are able to help me trouble shoot my issue. Thank you in advance.
