Battery indicator seems fine. Wrench symbol is lit. Chair won't respond to joystick control. Any suggestions? It worked when I put it away a few months ago and now, nothing.

The rippling lights on your Drive Seren mobility chair, followed by the chair stopping and the power sign coming on, could be indicating a problem with the battery or the motor. Here are a few steps you can take to troubleshoot the issue:

1. Check the battery connections: Make sure the battery connections are clean and tight. Loose or corroded connections can cause power issues.
2. Test the battery: Use a multimeter to test the battery voltage. If the voltage is low, try charging the battery. If the battery won't hold a charge or is more than two years old, it may need to be replaced.
3. Check the motor: Check the motor connections for looseness or corrosion. Test the motor by turning the chair on and listening for any unusual noises or vibrations. If the motor is malfunctioning, it may need to be replaced.
4. Check the joystick: Make sure the joystick is clean and free from obstructions. Test the joystick by moving it in all directions to see if it responds properly. If the joystick is faulty, it may need to be replaced.

If these troubleshooting steps do not resolve the issue, it may be necessary to contact a mobility equipment repair technician for further assistance.

What you refer to as the "circle" is most likely the low voltage battery symbol and flashing means to change the batteries. The wrench means fault which just goes along with changing the batteries.

A flash code of 9 indicates a communication fault. What this means is that there is a lack of communication between the joystick and the other electronic component, the controller module. In my experience, the usual culprit is that the charger plug makes bad contact inside the joystick housing causing it to heat up and burn. This can cause components inside the joystick to burn out. The other more common problem is that there is a break in the 4 wire harness going from the joystick down to the controller in the base. Sometimes it is just a matter of unplugging the connector, cleaning it, and pushing it back in. In other cases, the wire has been cut or broken along its length. Look for cuts along the black covering of the 4 wire harness (connecting cable)and twist and tape or splice and solder to repair the wires. These connecting harnesses are so inexpensive it is usually easier to replace, however a quick splice can get you going temporarily. If you smelled burning that would be an indication that the joystick assembly has burned out and I would replace that along with a new harness (connecting cable with a plug on each end) to the base electronic module.
The connecting cables have always been a weak link in this design and have had a history of failures over the years. For this reason I replace both the joystick assembly and connecting cable when servicing. Hope this helps.

Motors must be fully locked in gear to drive. Also many chairs require the joystick to be turned off before putting them in gear or turn chair off and back on after engaging the motors.

Time to replace battery - not taking a charge properly.

Your version has a Dynamic Controls model controller and joystick.
Unplug the charger and engage the motor/brake lever so the chair is no longer in free-wheel mode (con't push by hand)
Turn the chair off, wait 5 seconds, turn the chair back.
If chair still does not run and your wrench is flashing you have a problem. Count the wrench flashes - the flash count indicates the error detected. 3, 4, 5, and 6 flashes indicate and error with the motors.
3=Left motor fault
4=Right motor fault
5=Left brake fault (may not be engaged)
6=Right brake fault (may not be engaged)
Any other fault code usually means the electronics or wiring is bad and not worth fixing.

press the top button on your joystick the lights on the joystick will come on showing battery charge and speed wait about 5 seconds then push the joystick forward and away you go I would suggest placing the spped on slow until you get used to driving the chair

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

If he put in the batteries (2) properly, they should never sizzle. Some will emit a very minute spark when the final connection is made, but that is normal. There are fuses coming off of each battery to the power controller that will blow at 40 to 100 amps or so, depending on the chair; these will blow before the chair frying, or the circuit breaker will trip, or the controller will fry and all will be quiet on the chair, so I am going to say that the batteries weren't properly hooked up, otherwise on of the above items would have shut everything down. Continuous flashes indicate trying to start the chair while it is still on the charger, or with the joystick off-center. Make sure it is unplugged and notohing is resting against the joystick. If it's still a no-go, then you have either a joystick issue or controller issue. You will need to test those by replacing with known good controller/joystick, which a dealer should be able to do for you. Good luck.
