It depends on how it and the wheelchair are wired and how the voltage is derived.
Presumably the 24 volt wheelchair requirement is provided by two 12 volt batteries connected in series and these could be recharged in series by a 24 volt charger and a pair of wires or by a 12 volt charger providing a 12 - 0 - 12 using three wires where one 12 is a positive in relation to the 0 and the other is a negative in relation to the zero making a potential difference of 24 volts.
There could conceivably be circuitry within the wheelchair that requires only 12 volts for recharging and causes the two batteries to be charged separately, though while this method could be desirable and offer some benefits it would be considered unnecessarily expensive and complicated for most commercial purposes.
As usual you really need to know what is supposed to happen or is designed to happen before fault-finding can begin. One of the wires could be a safety ground wire but most likely it is used to provide some sort of feedback to the charger from, perhaps, a thermal switch close to the batteries so charging will cease if too much heat is generated.
Either the charger is bad or the batteries are too old. If the batteries are allowed to go dead completely the 24 volt charger will not recover. You'll need to seperate the batteroes and use a 12 volt automotive charger to charge the batteries. Make sure the 12volt charger is able to charge gell cell batteries. Not all will.
Bob why don't you run a small 2 wire cable from one battery to the armrest where your joystick is located and attach the new horn and a small push button switch to the joystick bracket coming from under the armrest. loosen the knob tightening the joystick bar and pull it out enough for you to attach the horn and button to it. I 'm not sure if that will work because I don't know what the new horn looks like but you can also mount the horn under the shroud near the battery and run the wire to the switch at the joystick. Good luck sounds like an good project
join them in parallel if there all 12 volt you could just charge the 1 battery with 12 volts and that would charge them all but all the other batterys have to be in series you cant do it if u have 2 24 volt batterys they all have to be 12 v
yep they are so that you are providing 24 v dc to power the motors. Your chair should have 2 battery boxes that contain one 22nf battery each and have the connectors that allow them to supply 24 volts to your chair. Hope this helps
