I HAVE A JET 3 ULTRA CHAIR, WE LOSS THE 24V PRIDE JET 3 Ultra Power Chair Smart Battery Charger, CAN WE USE A COMPUTER CABLE INSTEAD IF NOT WHAT CAN WE DO.

Question edited for clarity.

You have a dead short somewhere. You need some electrical knowledge and a digital multimeter for testing. Take all the covers off. Look for wiring that has rubbed through and touching or melted. Disconnect one of the motors and replace the fuse. If it still blows, reconnect that one and disconnect the other motor. If one motor doesn't blow and the other does, you know you have a faulty motor. If neither stop the issue, then you move up to the controller and look up there. With a meter you can check for shorts within the motors, as well as grounds.

Or just take it to a Service Centre and have it repaired and serviced properly.

Wall outlet bad? Charger not turned on/plugged in right? Something disconnected? Bad battery connection? Blown fuse in chair or charger? Bad battery or batteries?

lots of questions how old is chair, how old is batteries, it has 2 by the way 12v connected in series giving 24v , always change both not just one, check for loose connections first and be sure charger is good try on another chair and/or try another charger on yours if possible they are 95% interchangeable

Do all of the speed lights flash at the same time or do they ripple from left to right? If they ripple from left to right the chair is in lock mode and you can use the unlock procedures from my tips to unlock. If they are all flashing at the same time you have an internal joystick problem and the joystick needs to be replaced Hope this helps

Isabel you could have battery problems or it could be a charger problem. you would need to contact your provider (where you got the chair and ask them to check it for you) Now Plug the charger in for a couple of hours and look at the light on the charger (it is located under the rear of the chair) if it is green then it indicates a full charge if you have no light then it could be that the batteries are getting the charge or the chharger is not operating A tech will haveto determine the problem for you. Sorry I couldn't give you a instant fix Hope this helps
