well,,, um try getting it a new power battery?

bad charger

Take your drive units both out of gear and put them back in that will reset the computer and it started mine working again.

How many times does it blink?

To test the batteries you have to check them with a load tester. Just testing the voltage will not show if they are bad.

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.

Sure. Just slower. If you remove the motor from a power wheelchair to use in other applications keep this in mind; these motors are designed for PulseWidthModulation Speed Control (apx. 10kHz) with a feedback control to keep the speed more consistent. Feedback and pulsing is key to power and efficiency. If you run them at 12 volts without a pulse control the current to power output is much higher and the I*I*R (I squared times R) losses are higher - dissipated as heat. The motors will run very hot under a load with DC that isnt PWM'ed. If the use/cool down duration is short you should not have issues.

http://www.invacare.com/doc_files/1143190.pdf Owners manual for TDX SP link above. First check if you have power present at the charging port. If you have power (24 volts) then the batteries and wiring are not the issue. If you don't then check the battery post fuses. These are "L" shaped brackets with a white square fuse held on the positive post with a through bolt and nut. On older chairs these are known to become loose and or blow just when you need power or stop suddenly. Also check the big Anderson connectors at the power point at the end of the battery box. Check for solid connections. If there is 24 volts here to the control box, next check the controller connector. If there is +24 at the controller connector but 0 at the joystick charger port you have big issues. Either the traces connectors in the controller are fried or your joystick has major issues.

Hi Mark. Reversing the polarity:There are 3 wires on the Wig Wag Assembly. (reverse the wig-wag function) simply de-solder the 2 outer wires & swap their position & re-solder.I would seek a price for doing the job from an approved scooter repairer,unless you are comfortable doing the job yourself.I hope this has helped,Colin
