Where can I find a wiring diagram for this power chair?

There are a few things that could happen. Without looking at it, I really cant say what the root cause is. The common issues are: 1) a loose motor connection 2)a loose battery connection but this should correct once you cycle the power 3)a bad brake solenoid. Just recently i had a similar situation and the indicators showed that it was a bad joystick, when i checked the wiring harness, i found a broken wire to the brake solenoid. Get a tech to look at it first. It may be a simple fix. They should be able to narrow down the search if they put a programmer on the controller to see what the actual fault is. Please inquire if they have a programmer that will work on your chair before they come out. I think this will be the only way they will be able to quickly identify the issue.

Yes of course if it was made with the unit its was important then as
well as it should be now contact manufacture. Reset buttons reset micro processor functions as well as reset the unit memory capability.. Hope this helps God bless

for that go to invacare tech

that is a tricky one definitely a loose connection need to find it by trial and error wiggle wires while driving till it stops. best to call for service from a qualified tech

When you turn the chair on and move the jostick the wrench light will flash you need to count the number of times it flashes to determine whats wrong ie 4 flashes pause 4 flashes pause. If its 4 flashes then you have a motor problem see my tips on flash codes to determine the problem. Whatever the problem is you will have to have the chair fixed by a tech or the provider that sold you your chair Hope this helps

Hope you have had this fixed by now. But in case not and you are not able to use the chair.
If the chair still drives it's not batteries. The toggle switch box should be ok if there is no visable damage to it. Bad connections of the wiring from the toggle switch box to power or the recline or tilt motor should be inspected. A electronic tech is needed for most electronic failures.

Hello mmcpowers,

For the Pride Jazzy wheel chairs you can locate what you need at the Jazzy website at the following link http://www.thescooterstore.com/products/product_manuals.aspx
When on the site you will locate the chair you need and the wire diagrams are in the owners manuals. As a common problem is just a plug coming un-wired they tell you where they are and the wire configuration. If you tell me some of the other chairs you are dealing with I will try and locate the website for them as well.

Thank you for choosing FIxYa.com

Will you don't say what chair you have and they can all be wired differently. Look under the shroud that covers your batteries and see if there isn't a wiring diagram there. If you let me know the brand ie: Pride Jazzy, Invacare M51 etc. I can give you the proper wiring for the batteries. Now you also didn't say if you charged the batteries after you installed them. Remember always charge before use. Just because they are new doesn't mean they are charged (in fact they could have sat on the shelf for a while). Make sure that they are no older than 4 months old even new batteries can be bad. Charge these puppies overnite. When you plug in the charger you should see a red and yellow light after charging overnite you should see a red and green light( indicating full charge) If when you plug the charger in you get a red and green light then something isn't wired correctly. Hope this helps

The wiring is pretty simple and straightforward. These operate on a 24VDC system provided by two 12VDC batteries. Power from the batteries goes to the controller into a Joystick/controller combo. It leaves the joystick down to each motor/gear/brake assembly. Power to the batteries comes from the charger which puts out 28VDC, with a 120VAC input. Very rarely does any of the wiring go bad excepting those people who grossly overload the chair, or run it into fixed objects at full speed. Other mishaps with overamping are caused when somebody tries driving over unstable surfaces like sand, gravel, mud/wet grass and spin the motors. This drives the controller crazy because its job is to keep the chair pointed in the right direction, and with wheels spinning, it doesn't know what to do. Overheating the motors or controller, or both. There are two sets of "brushes" on each motor that carry the current from the batteries to the motor. These are located under a black-plastic slotted screw port at the ends of each motor. Removing the plastic screw reveals the brush. It should have a flexible semi-copper lead that shows no evidence of overheating, or brittleness, and should be about 3/4 of an inch long. If 1/4 of an inch, it should be replaced. Check all four. Good luck.
