First check the Freewheel lever on the back of the chair. Click it back and forward 2 or 3 times to make sure it's seated correctly. Have you had the batteries removed recently? Recheck the battery pack is seated correctly and any wires connected are clean and connected to the correct positions.
If this doesn't sort out the issue you will probably need to get a technician to test if there is power getting to the controller. If there is power there it could be an issue with the actual controller.
try connecting the 12v to the line that comes out of the big transformer and goes to the chair (should be able to unplug)
On my mother's chair, the voltage that comes out is ac, but is rectified inside the hand control, the thing is it may be rectifying one half of the ac to open the chair and the other half of the rectified ac to close it again, so might only work one way
That is possible. Check the power circuit from the battery and see if there is any loose connections or resistance in the circuit via the voltage drop method. Here are some links that may help:
With new, fully charged batteries, you can get a good 8 miles at full speed with a normal weight load on the chair. The chair goes about 4-5 mph, so an hour and a half or more at full speed on level terrain. Be sure to always recharge daily, keep the chair on the charger when not in use(batteries will die if you don't)and avoid running the batteries all the way down....try to stay in the top 2/3 charge range and you will get more life.
first only charge the chair prior to using it, constant charging will dry out the batteries. though not likely the batteries now sounds like a loose connection somewhere, batteries just don't stop they fade out slowly. look for loose connector
Remove the batteries .. Every Chair is different .. but if the batteries aren't charging it's probably that they were left uncharged for a time and they dropped down enough that the charger dosn't recognize them .. If they drop down below around 6 volts the charger won't charge them ... I have taken batteries out and charged them individualy with a car charger .. but they never come back .. at best half life.
How long have you noticed the decrease in speed? Are you charging the batteries regularly? Have you checked your air pressure in your drive tires? If the batteries are getting old or the power chair has been stored for a while, the batteries may not be taking a full charge. If your speed indicator is showing full like always but the power chair is not responding like it used to, it may be a battery issue. As you operate the power chair, listen for noise and pay attention to see if there is any vibration, this may indicate a mechanical problem that is causing power drain. If not, your power chair may still be within normal parameters, just not "new out of the box" anymore. Make sure that you decrease your speed when going up inclines to avoid excess wear on the motors. Good luck!
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.
