    Charger does not charge (green light only) help!

    Update: Apparently the overloading stress or something caused the charger to stop during a charge and now I do not get even green light or output voltage anymore. Took it apart and applied more magic stare with no success. Also wiggled all the components and wires with a plastic stick while...

    Charger does not charge (green light only) help!

    Wow, that looks bad, thank god it was only one room and not the whole house. I charge it outside since taking the risk as a certainty and preparing for the worst is a better option than trying to avoid it forever (which makes me not take precautions at all, you can see from the mess in the...

    Charger does not charge (green light only) help!

    Update: Turned the potentiometers a few turns to each side but no change in the frequency of the clicking was observed. Test was conducted with indandescent bulb as load and green light only. It appears that the bigger the load the faster it clicks as with no load is very slow, with bulb faster...

    Charger does not charge (green light only) help!

    The smoke was because of a short of dirty flux in the FET, each spark generated more coal which made it worse. With my soldering I also made the gap smaller. I am sure the ticking is because of turning off and on repeatedly as the light blinking in rythm with the sound confirms. Is an overload...

    Charger does not charge (green light only) help!

    Update: Bored with research, decided to plug back to the bicycle and see what happens. The bicycle is charging with the clicking charger! The bicycle right now is at 41v. Charging in this state makes the clicking, maybe it is the CV state? Will post results after I try to charge a depleted...

    Charger does not charge (green light only) help!

    Update: The smoking was caused by gunk I left on the FET's feet when reinforcing the general soldering of the charger. Cleaned and is "working" again with the clicking which is not normal. I am scared of this charger in general since I absolutely cannot leave it unsupervised. Please help. I am...

    Charger does not charge (green light only) help!

    Update! It started working again, charging but with clicking noises and then a FET smoked. Do not know how to replace. I have a few computer power supplies around, they have FETs, wonder if I can just swap them regardless of model (most likely not, but I already think of this as lost cause).

    Charger does not charge (green light only) help!

    The SLA charger I got measures 41.5v in the output. Charged with the bicycle on to check it's voltmeter, seems ok so far, as you said, it stops at 41v, I am ok with that for now. Will replace wires and post results.

    Charger does not charge (green light only) help!

    Update: I hooked the charger directly to the bicycle controller and tried to turn it on. It failed, shutted off immediately and did not even light the dashboard. Fuses are still intact. I am still unable to make the charger output power. Update 2: Tried hooking an incandescent bulb to the...

    Charger does not charge (green light only) help!

    What if I decrease the cut off current so that it won't cut off and start the charger? Maybe the battery is not accepting the full 5A of the charger and it is considering as full, I dont know, brainstorming here, tests will be ran tomorrow.

    Charger does not charge (green light only) help!

    I believe the battery is fine, the charger port of the battery reads 36v (the current state of the battery) and it charges with a 42v 1.5A lead acid charger I have lying around. (didn't do a full charge with the lead acid charger, read around it is dangerous). I do need to find out if it can...

    Charger does not charge (green light only) help!

    Hello everyone, I bought this charger and it has the famous green light problem. The red light and fan does not turn on to start charge. I need your help to make this charger trigger on and function again. One thing I think might help are the two potentiometers in the picture that I do not...
