When I drive forward and move the joystick to center the chair is still moving for the few fit before stops.

Hello, I'm trying to bring back to life an old Invacare Arrow Storm for the friend who's got Parkinson D. and cannot move around by himself. Everything went more or less O.K. except one thing : when I drive forward and move the joystick to center the chair is still moving for the few fit before stops, I've measured of brake coils and in both motors it is 75 Ohms. What should I do to fix this problem? Best regards, Eulogiusz Drzewiecki

If the brake is applied by electromagnetism, power must be supplied to the coils by either manual or electronic switching.

I suggest you investigate the circuit to discover how the power should be supplied to the brake coils and then it will be easier to trace the fault.
As a matter of not unrelated interest, it is fairly usual to arrange the wiring/switching so when power isn't being supplied to a low voltage DC motor the motor terminals are shorted. When being pushed the motor becomes a generator and the input becomes and output and so shorting that output makes the motor self-braking to some extent - this is why car windscreen wipers are able to stop almost instantly...

SOURCE: Invacare Arrow power wheelchair, display

If you have made sure that the freewheel levers are in the drive position and after turning the power on and you are still getting the barke error then the motor and brake assembly will have to be checked by a tech and possibly have to be replaced There is no self fix for your problem Sorry Hope this helps you

THE BATTERY LIGHT CONTINUSLY SCROLLS FROM LEFT TO RIGHT AND CHAIR WILL NOT MOVE

Turn on Joystick and push horn twice, you are in locked mode. If this didn't work then turn Joystick on push gimbal forward until you hear a beep, then move the gimbal back until it beeps you are now unlocked. Gimbal= what you push to go left right forward or back on a joystick.

It won't power off or move

If nothing looks broken on the joystick the batteries may have become disconnected when the chair hit the ground. Check all wiring connections on the chair. You can test to see if there is voltage getting to the joystick with a voltmeter.

Hoveround won't move.

Double check to be sure drive levers are fully engaged. Go down and up a few times. If problem persists have Hoveround come and check it out. One of the drive motors may have shorted out when you continued driving with gravel in the wheel.

Jazzy 614HD will not move. Lights flash from right to left, then cuts off. Unlock instructions are not effective. Chair is fully charged.

If chair has a tilt, recline or lift seat on it it may be going into lock-out mode on its own due to a limit switch fault. If you don't have any of these options then I suggest you remove the joystick, controller and any wire harness between the two and send them to a shop like mine for repair.
The usual lock out light chase is from left to right - not right to left so this is suspect of a different issue.

It will move side to side But it has no forward and reverse and the batteries are brand new

contario With little information other than what you are telling me your problem seems to be the joystick. If the chair's joystick will make the motors turn your chair but won't go forward or back then the problem is in the joystick and will have to replaced. Sorry hope this helps

The power indication display is flashing with all colors visible.

The flashing will come on if the chair is in neutral or if the charger is still plugged in when you turn it on. Place the chair in neutral (freewheel) by shifting the levers out, then place firmly back into drive.

Unplug from the charger and it should fire up. Sometimes, the chair will also go into "sleep mode".
Check your owners manual for this. Note, some have sleep mode potential but it's not in the manual, and if someone inadvertantly hits the right series of motions with the joystick, you can inadvertantly put it to sleep. Try turning the chair off, wait three seconds and power back up, then immediately press the "horn" button. This wakes up most of them. Others you need to power off, turn back on and then move the joystick forward, backward then forward again.

Good luck
