The battery charger seems to work fine. I get a

bad controller. try ebay

Check the charger output to verify whether or not you have a bad charger using a voltmeter. These smaller batteries are notorious for having a short shelf life and poor quality control from the manufacturer. Load test the batteries after you verify you have a working charger that will bring the batteries up to the proper voltage first.

Replace the batteries and charge before use then charge nightly for 20 days Use the chair daily so you can get a good charge nightly to get the batteries operating at 100% After the 20 days If you don't use the chair daily always store fully charged and then charge once a week overnight. Should work fine once you get the new batteries in You will need to get 2 U1 batteries for your chair do not get Wally World or automotive batteries You must replace with sealed deep cycle batteries made for power chairs Hope this helps

Angel the charger light should only turn green when the chair is fully charged. If you know the chair isn't fully charged then there is a problem with the charging system. if the circuit board in the joystick got wet then that is a serious problem. If you have a voltmeter you can check the battery voltage thru the charging port located under the front of your joystick Set the meter to 200 volts dc and plug the leads into the 2 outter holes of the charger port. Fully charged you should read 27-30 volts if you aren't getting any reading then the batteries are completly dead or there is a problem with the charging circuit (the reason you are getting a green light on the charger) The joystick will have to be replaced sorry If Medicare paid for your chair then they will pay 80% of the repair costs to get your chair working again If they did contact Roadrunner Mobility @ 1-800-467-2668 to get it fixed thru Medicare Hope this helps

Phil the red means battery is low and the green is a speed limit code because of the low battery if you have charged your batteries and you still get the red then you need to check the charger after charging all night does the yellow light on the charger turn green? if when you first plug in the charger if the red light is on and the other light is green then there is a problem with the wiring or connection to the batteries from the charger and you aren't charging the batteries. if when you plug the charger in and you get a red and yellow light then the charger is working but you don't ever ge a green light and the battery level gauge is still showing red then you need to replace the batteries Hope this helps

After you changed the batteries, did the power chair sit unused for several weeks? It sounds more like a battery or fuse issue than a charger issue. If there are blinking lights when you try to turn the power chair on (not while attached to the charger), or it comes on then goes back off by itself quickly, there may be something else going on.
1- The green light on the charger is telling you that the batteries are not accepting any more power, either they are fully charged or they have oxidized/gone solid from sitting without being put on the charger for too long.
2-The scrolling lights on the controller when the charger is plugged in just confirms that the chair is connected to the charger, so it sounds like everything is connected properly and working. The horn will work fine when it is attached to the charger as it is getting power from the wall outlet.
3- If it was a fuse issue, the lights would not come on at all when the charger is NOT attached, even after the battery has been fully charged, which is what it sounds like is going on. The fuses can blow if you operate the chair on a slick surface or one of the drive tires spin out. The batteries will be fully charged but because the circuit is not complete, the chair will not power on.

I recommend checking the fuses and changing them if necessary. You are in luck because this is a relatively easy and inexpensive fix as they are standard automotive fuses found at any auto parts store or even Walmart for around $2 each (you need 2). The fuses are located inside the gray battery covers under the seat, attached to the leads connected to the battery cables. The straps holding the covers on the batteries are tight, you may want to use a flat head screwdriver to help release the clips. While you are down there, inspect the tread on the tires, if it is worn or slick it may need to be replaced for safety.
I hope this information is helpful to you- good luck!

If you have an off-board charger that plugs into the joystick there are two lights on the charger one red(power on) and the other yellow (turns green when fully charged). Plug it into the chair and if the light is green then you have fully charged the batteries. Now if you have the on-board charger the charger meter on the rear of the chair will resd zero when fully charged. Hope this helps ya

The chair will not move if the charger is plugged in. The flashes are normal with the charger plugged into the chair. The lights on the charger mean that the batteries have been fully charged. Red and yellow lights mean charging. After you unplug the charger from the chair (if off-baord charger, turn charger off or unplug from the wall) then unplug from joystick. after plug is removed from joystick press the on button and all the battery lights should be lit and when you move the joystick forward you will hear the electric bake release and the chair should move forward etc Hope this helps

Have someone check if the on board charger light is green after you have charged it all night. Most probably you have a charger problem and this will also create a battery problem since you haven't been charging them with a bad chargger. If medicare purchased your chair then you can find a repair service to repair your chair and Medicare will pay for most of the repair

Your batteries have shorted out internally. If you have a 2/10 Amp car battery charger, you may be able to bring them back to life like so...

- Switch the charger to 2 Amps
- if your chair uses two 12V batteries, connect the car charger across only one of them. If it uses four 6V batteries, connect across two. Be sure to match red to plus and black to minus!
- plug in the charger and watch the Ammeter meter. If it "pegs" and won't come down, the battery is toast. If it goes down to aboult half, you are on your way.
- When the meter gets down to about 1/4, switch to 10 Amps. The meter will again go up.
- When the meter drops to about 1/4 again, the battery is charged,
- Repeat above for the next battery.

This process will take several hours per battery. You don't have to remove the batties from the chair. However, it would be a good idea to do so in case a battery fails.

Good Luck !
