You should call the manufacturer for this type answer you need.

Sounds like a wire has broken or come apart. If playing with the neck it starts sometimes that is the area that could be the problem.

if you put pressure on the chair in one direction or the other while trying to disable the brakes it will make it difficult to move the lever. I’m happy to assist further over the phone at https://www.6ya.com/expert/bill_bcbb89783b08c489

Hi flashing lights 8 times (Controller fault.). if the batteries haven't been used for several years U might have to replace them .U can buy a BATTERY LOAD TESTER OF E/BAY cost approx,$36..this will give U an accurate test on the condition of the batteries ,good luck

Make sure that you are charging the chair 12-14 hrs before driving. charge with the joystick on, make sure both freewheel levers are in locked position. I’m happy to assist further over the phone at https://www.6ya.com/expert/bill_bcbb89783b08c489

If your chair is in freewheel (levers on back of motors not in drive) then the light will flash. But are the lights scrolling left to right or right to left? You can check for freewheeling by trying to push the chair from behind if it moves easily then it is in freewheel and you will have to move the levers to the drive position. You need to give more info of the flashing lights are all the lights flashing are only some flashing? etc

The M91 has an onboard charger. When unplugging the charger power cord from the wall outlet does not stop the chair from being in the charge mode, The charger has to be unplugged from the wheelchair wiring harness or main control module under the plastic body parts. The on-board chargers fail like this sometimes.

They are diagnostic codes to help troubleshoot a possible problem with your wheelchair. The lights blink in patterns. You have to count the number of blinks and what color they are.

Test the battery voltage at the joystick where a programmer or charger would plug in. There are 3 holes, the top or number one hole is the positive hole for a voltage meter to plug into and the bottom or number two hole is the negative hole for the volt meter. Plug in the meter and see what the voltage is when sitting still and keep the meter in and see what the voltage does while you are driving the chair. The voltage should not drop more than 1 or 2 volts from that which you had when the chair was not moving. If the voltage drops more than that then there is a problem with charging or the new batteries. If the voltage remains good then the joystick or speed knob control could be the problem.

Your chair has a motor problem. The code does not tell which side it is. Make sure both motors have the brakes in the drive position before turning on the chair. Also check that both motors are plugged into the main control module in the base of the chair.

5 blinks means the brake has a problem http://manuals.monsterscooterparts.com/mobility/Invacare/manual-invacare-lynx-L3-L4.pdf

The chair may be in what they call SLOW MODE or the batteries are weak. If you have powered seating on the chair the seat has sensors that make the chair drive slow or not drive at all when the seat is tilted or reclined or raised. A sensor can go bad or get out of position. The joystick could have different programming for different drive modes. Try changing drive modes.

The red light on the transformer/Charger means the charger is bad. Sometimes it can also be battery harness wiring. Most often it is the charger that needs replaced.

You are getting a motor error code. Check motor wiring and connection to the main control box. Motor may have gotten unplugged when changing the batteries.

The ON button is at the top front of the joystick. If this button does not turn on the red, yellow and green lights there are many possibilities as to why it is not turning on. Batteries have to be checked first for proper voltage. Then wiring needs to be checked for proper connections and fuses checked.
