It could be many things. If you just bought the scooter, it could be a loose wire in the electrical system. Did you check the battery terminals to make sure they are tight?
Mine is an Invacare M51 Pronto Surestep with an onboard Winsunny battery charger. My charging lights are solid red and green/ yellow. Depending on if it is charging or not. What kind of charger do you have?
I have to replace my charger because it is not working. My green light is staying green while charging even though my joystick is showing my batteries are depleting and I just got new batteries. sigh.
hi the red led should not flash the green led should only come on when batteries r charged while charging the green led turns orange or yellow....can u borrow another charger just to check to c if its not the scooters charging circuit that is the problem..or the batteries ..good luck
make sure battery cables are secure at battery terminals and clean.how old are the batteries.If the batteries run down fast they are no good.a good way to test them is put scooter against some thing solid and go forward.If the battery indicator drops to o the batteries are no good.It takes about 10 hours to charge the batteries
according to manualslib type site for the wg540, solid red means charging for the wa3840 and wa3838. After 30 minutes if battery has not reached 10 volts (of 18), the red will begin flashing meaning defective.
Just green? Ready to go. Green flashing? Overheat.
Tangent; sometimes a discharged battery needs a little coaxing - have to get a little voltage into the battery for charger to try to charge. Different company, electric drill. I plead ignorance if this applies for the 3840 since they mention the half an hour time.
OK ... after a lot of trial and error, I got mine to work. I think it may be a really low charge or something. I had to press the power button until it was completely dark ... no flashing faint green or any colors. Then when I plugged it in, I got a solid red and left it for awhile. Then when I pressed the power button I got yellow, red and green ... the computer recognized it and then got a solid yellow.
Before when I had it plugged in, I'd get a lot of red random flashing ... and it just didn't seem to charge at all ... even after a full day.
I think the issue was that it was in this "flashing state (red when connected, very faint green when disconnected)" It wasn't easy to get it to turn off completely. Most of the presses of the power button didn't change the state at all. But if I got it just right, I could see the faint green light go off. That's when I plugged it in and got a solid red light, and eventually a good charge.
