Where's the other motor? That controller positively will not function unless both motors are connected. The little 3 pin connector is for an external charger. The blue connectors go to 2 12 volt batteries to supply plus and minus 24 volts. If you hook up the batteries, the lights on the joystick module will blink error codes that will say Left (or right) motor fault and brake fault.

I thought I read about guys on here running just one motor. As for the connectors there are also two black ones with + and - signs on it so I thought that might go to batteries. The blue ones are the problem.


theres another blue connector coming from control box that I dont know where it goes.

I use just one motor. But I use this controler to do that.

I tried responding last night, but had a bad connection here. :(

Anyway, as others pointed out, you will have to have both motors hooked up unless to install what Kbeitz is showing you.

I have two of them for my set up, but yet to install them.

Ok will try to upload better pics this evening. Pretty sure black plugs go to battery but don't kno where blue ones would go

revid

Might have to go hunting for another motor I guess

Kbeitz

Most of the time he motor has 4 wires. Two of them would work the brakes on the back of the motor.
Just maybe your blue wires might be brake wires. I dont see any brakes on your motor.

    The motor and controller I used on the LM Mark 4 Norwood came from
an Invacare Chair. The controller looks different than the one you have
but mine worked with only one motor connected. The wires for the other
motor just hung free. Either set of motor wires worked the motor depending
on how I leaned the joystick or held it in center which would have controlled
both motors if attached. I cut the wires to the brake and connected the black
and red wires to the battery through the controller.
  Here is a picture of the motor I still have (sawmill was sold) and pictures of
the set up on the sawmill. I don't have a picture of the connections on the mill.

Got the motor hooked to control box via"right" labelled plugin and then control box to joystick via respective plugin. There's a "left" labelled plugin and a blue three slotted plugin coming out of control box that has no where to plugin to. Will upload some more pics

fishfighter

That last plug might be to go to the batteries. Don't know for sure.

revid.....I have another wheelchair with connections that look to be similar to yours. It is an Action Power 900.... Will your 2 blue plugs connect together? Here are a couple pictures
showing connections on this one. Your two black plugs with red and black wires
look like these and they each connect to a separate 12 volt battery. They
connect together downstream to make 24 volt.

thanks guys, when I first looked at the blue plugins I didnt think they would go together but when Slingshot posted his pics I had to go take another look and they do.Sorry about that fellers. I'll just cut the black ones going to batteries and put my own battery hookup.Slingshot our motor setup works ok with just one motor?? Some guys here says it will never work,I guess it may depend on type or Brand of wheelchairs .Will try to hook up later with one motor and see how it goes.Again thanks for all the help

Slingshot


The joystick is similar to yours also...anything more you may want me to check  I will be glad to do so..
A couple more pictures...

Going back and looking at your first picture, your joystick looks just like mine.



 


Model number, if that helps.

There may be some controllers that might work with just one motor. It's a safety check thing. On power-up the controller normally goes through a check out procedure, where it checks both motors and both brakes. Also makes sure the joystick is in neutral. Think about it, this is a wheelchair. Powering up with one motor or brake disabled or joystick in full power position could result in some violent maneuvers, possibly tossing occupant on the floor.
All controlled by an on-board programable micro processor ie computer..
Dynamic Controls, the manufacturer of that controller has a very nice web site, where you can down load an installation manual with everything you ever wanted to know...

Could someone with programming knowhow remove or modify the check for both motors and brakes part of the startup so one motor could be used with the chair control?

Nope, the control program is more or less permanent. One thing that might work would be to wire a couple of light bulbs in place of one motor and brake. I haven't tried  this but I will when I get another one in the shop...
