When the charger isn't attached to anything the amperage reading should be zero, not "kinda high". Sorry, providing further troubleshooting suggestions without having the charger in front of me is beyond my communications skills Good to know whomever makes these chargers also doesn't believe in testing before shipping, just like Gotway Most of the charges show .05 or less when nothing is plugged in. But the eWheels 84V smartcharger shows 0.23A with nothing plugged in, so i didn't think much of the fact this 10A "smart" charger (with no special switches for charging speed or 80%/90%/100% auto off) was showing 0.5A with nothing plugged in. But I can assure you this product has gone though rigorous quality control testing before it left the factory as evidence by this little sticker. 1 hour ago, houseofjob said: Perhaps the cutoff/full threshold is set wrong, as @Rotciv has instructed me in the below post: I think i found the little blue with gold adjustment screws for the Potentiometer as referenced in the other thread which would control output. The other adjustment is to control the threshold to actually kick on the charger? or does that giant "84" glaring at me tell me they built this thing with the wrong parts to be a 100V charger? 1 Quote Link to comment Share on other sites More sharing options...

FYI, this is just one of the several generic chargers you can find on AliExpress and configure to your needs (if you know what to ask for, and better if you can solder): https://www.aliexpress.com/item/32961214439.html Also, while in the EUC world, we for some reason use maximum voltage (4.2V max x 24 cells = 100.8V or "100V"), the other PEV worlds seem to go by nominal voltage, so either 3.6V x 24 cells = 86.4V, or 3.66V x 24 cells = 87.84 32 minutes ago, maltocs said: I think i found the little blue with gold adjustment screws for the Potentiometer as referenced in the other thread which would control output.

Every charger is slightly different, but without claiming to be an expert here (and as @Rotciv has indicated for the Wate charger models), the blue potentiometer nearest to the output charging plug seems to usually be voltage control, while the other 2 are current and charging threshold. Measuring current/amps, I'd just rotate one at a time, noting the original position, to figure out which is which (totally didn't realize this when trying to tinker and re-purpose my old 67V v2 eWheels charger).

Heres a video of the not working charger. but don't rack too much brain power, i already contacted Green Fashion. Quote Link to comment Share on other sites More sharing options...

Popular Post mrelwood Posted August 22, 2019 Popular Post Share Posted August 22, 2019 As Marty said, troubleshooting through a discussion forum is extremely difficult, unless the issue is a well known one. The 1.5V difference could be just a protection diode at the wheel's charging connector. Or as you said, just a difference in precision. Even my $100 multimeter only has a precision of +-1% at 100V. I would (re-)check that: The cables from the charger's switch to the board are connected properly. The output connector has the voltage at the same pins (and same polarity) as the working charger. Fuses onboard in the charger measure (near) zero resistance. All the cables inside the charger are connected properly. All component legs, cables etc are soldered properly. All components look healthy. ! ! ! Note that when plugged in, the charger has lethal voltages at several random places! If you operate a plugged in device with the cover removed: Do not touch anywhere with your fingers, a bare metal screwdriver etc! Keep your other hand in your pocket! Make sure you don't touch anything metallic with your body! While measuring the output voltage of the charger (not connected to the wheel!), you could try and adjust the internal potentiometers. If the output voltage changes, turn it back exactly where it was, and never touch that one again. Then try to find another pot to adjust. If the pot seemingly has no effect and you feel brave (or desperate), connect the charger to the wheel and adjust the pot. When doing so, I would have the charger plugged into an extension cord with a switch right under my toe. 4 Quote Link to comment Share on other sites More sharing options...

In the end, I got the fast charger he promised. I just had to do the $1 purchase AGAIN. I never had to send back the bad charger. I'll keep it for parts in case the new one break as the wires don't like they are screwed/crimped in well. 1 Quote Link to comment Share on other sites More sharing options...
Jean eRide.ie Community Posted October 17, 2019 Share Posted October 17, 2019 Thanks for the update, how often are you using the charger and how do the connectors look so far? I was going to get a 100v 10A charger too, but I've been advised to get a lower one, so I'm going for a 100V 6A for the GX16-5 connector not to melt one day...

maltocs Posted October 17, 2019 Share Posted October 17, 2019 it good to have a backup charger, but honestly, i NEVER use it. just once to test it. The stock charger is plenty fast enough and the whole reason for buying an 1845WH wheel is so i don't have to charge midway on a ride. Well, at least with my riding habits anyways. Because of the ever so slight increase in power on this wheel, if i had to do it over again, I might just do the 2100 84V at about the same price so i wouldn't have to deal with buying spare chargers as my other 84V gotways use the same charger. You can see some slightly exposed wire under the insulation. I just need to loosen the screws and cram the wires in there and retighten. I'm just afraid of something touching if I cram too hard. But as I never really use it at all, it's not priority one for me. I wish it had an 80% or 90% auto stop like the ewheels fast chargers do, then I'd use it a lot more 13 minutes ago, Jean Dublin said: how do the connectors look so far? 2 Quote Link to comment Share on other sites More sharing options...
