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?

Mark Batteries your charger is putting our enuf 13.15 volts for each battery so after charging all night you should be reading about 13 volts on each. If your batts are only 12 volts after all night charge then batteries are weak Hope this helps

You can find the Fuse behind the foot rest. Take the pin located under the foot rest, and the casing will come off exposing the fuse.

You'll have to get to the battery terminals while they're charging, and then you can measure the charger voltage, if any (around 12 v).
It sounds like your charger is bad, and you can order one from this site:

Good luck, and hope this helps you.

The charger is defective. I would not try to charge it externally because if you charge it with a higher rate of current (amperage) than the original charger, it could explode or leak.

Only the red light comes on jazzy select charger


Batteries must be stored on a full charge. For extended periods they should be disconnected. If your batteries are flat/dead the charger will not attempt to charge them. You should remove your batteries and check and try to charge them individually. Sometimes they will come alive, must of the time they won't. Charge them individually with a 12 volt 2 amp charger - no higher; or in series with a 24 volt 4 amp charger.

Is there fuses in the M91 Pronto Onboard charger


I had this exact same problem after having my M91 in the shop. The repair man said that the onboard charger was bad, so he sold me an offboard charger to charge through the arm. That didn't change anything. I finally took it apart myself and discovered that there was a cord leading from the onboard charger to the batteries that the repair person had left unplugged when he installed my new batteries.
What I'd thought was "fast draining" of the batteries was actually the batteries self-charging overnight (which they will do a little bit if you let them sit). Of course, this might not be your problem, but I'd say at least look at it as a possibility.

I have a brand new scooter the batteries wont hold the charge


Bill have them replace the batteries. They are under warranty for 6 months and the provider is responsible for providing free replacement batteries under warranty. If they won't contact the manufacturer of the chair and explain your problem (that the provider will not replace bad batteries) they should require the provider to give you new batteries or send some to you. Make sure that you charge the new batteries before use and that you charge them nightly for 20 days If you use the scooter daily charge it every nite when you go to bed and unplug it in the morning hen you get up. Remember to have the power off to the charger whenever you plug or unplug it from the scooter. if the charger is an onboard one then just plug it into the wall and unplug when charged Hope this helps

Sweet you do not need to leave the charger plugged in for several days. Sounds like there is a charger problem When you first plug the charger in with batteries depleted you should be getting a red and yellow light with the yellow turning green when fully charged. now the charger (built in) could have become unplugged from the power module located in the rear of the chair behind the black cover. To get to it you have to remove the seat, shroud and batteries then using a phillips screwdriver and adjustable wrench remove the black cover. The charger cord will be the last one on the left with a small 4 pin white plastic plug make sure it is well seated in the power module. If it isn't loose then you have a problem with the charger or the circuit. Now if you know of a friend that has an off board charger for a chair or scooter that you can borrow you can charge the batteries using the charger port located under the front of the joystick Plug the charger into the port then into the wall socket and let er rip Charge until the light turns green overnite is a good habit to get into If the onboard charger is bad I would suggest you by an offboard charger (cheaper) Now if Medicare paid for your Dads Chair then they will pay for any repairs even batteries and you can contact the provider that your dad got the chair from to see if they will repair it Hope this helps

Chair dont take a charge


Get new batteries If your batteries are 2-3 years old its time for new ones. You can check the output of the charger by using a digital voltmeter Set the meter to 200 vdc and plug it into the two outter holes of the charger port with the charger plugged in you should read 27-30 volts. and with the charger unpluged you can aslo read the voltage of your batteries. fully charged they should read 25 -27 volts. If when charging you don't read 27-30 volts then the charger isn't working and you can get an offboard charger cheaper than the onboard just charge thru the charger port on the joystick. Hope this helps

Should the onboard charger be plugged in 24/7?


I won't leave them on constantly. How about a timer for the onboard charger. Set it for 30 minutes a day. You get 3 1/2 hours a week and the batteries won't heat up.
