Some chairs, like the M91 are a real bear to replace the batteries and connectors can get knocked loose in the process. First, using a voltmeter you need to see if the controller is getting power. On the DC setting, use voltmeter at the three-pin female connection at the joystick that is the charging port. The two pins that are opposite each other are the "hot" pins, and your meter should read about 25 volts, +- 2 volts. If its 0, there is a connection that isn't made from the batteries through to the controller, or the controller or joystick is shot. If you do have power to the joystick, then it's probable that the joystick is shot. A new one from Invacare is pricey, around $1,000.00 I have found a new site that can repair most makes. I have not used them, so cannot vouch for their work, but give them a call and see what you think.

If you don't have power, start at the terminals from the battery, and follow each wire back to the power control box, unplug and replug firmly as you work your way back. Check all fuses on the way. Then check all of the other connectors inside the chair, unplug, and reconnect again. Unplug and reconnect the wires leading into the power control box, and then restart chair. If no lights still, then the power control module is probably the culprit, but the address above fixes those too. The joystick and the power control module work together to make the chair operate safely. Good luck

Hi DREADFULPCBU

There isn't much to the P9000 joystick and controller. First and formost have your batteries load tested to ensure you have 24 volts dc. That in itself may solve the problem. I would then check each and every wire connection to make sure there is good continuity on all metal connectors. Check the voltage to ensure ther is only 24-27 volts dc. You could also have an over voltage possibly caused by a short somewhere. Has your chair ever gotton wet? If so one of the motors could be shorted out. Test this by taking out the motor brushes (one at a time) .See if it has water or oil on it. If so you may need to replace that motor. If all that is ok then here is where you can send your joystick and controller for repairs. ( I'm not confident that the ones you got from the junk yard are good.
