On some scooters it is possible to change the polarity of the motor. If its a two brush motor (most are) you can just swap the red and black wires around in the connector plug for the motor. Make sure you get the right wires if you do this but I have to point out that there is obviously a problem with the scooter and I would strongly advise you to get it looked at by your local dealer as the problem is potentially serious and may cause other problems aswell. I cant really understand why it would only go backwards. May be a throttle pot problem or main controller fault. Either way, as I said, best get it looked at as even if you do swap the wires, it is most likely that the scooter will only travel forward at the usual speed for reverse, normally 2mph! Hope this helps...

SOURCE: invacare auriga looses power
Hi. Most probably its the throttle pot ( Wig Wag ) thats causing the problem. I am an Invacare service agent and I have changed these many times for this very reason.Also check motor brushes are not worn down or jaming. Good luck. Neil.

Hi. I have had a few scooters that have had this problem after sitting for a while. The brake lining is stuck to the body of the brake assembly. When the brake is energised by the controller, it can't release.
De-clutch the machine like you did, and try rocking the machine back and forth. If this doesn't work you might have to have a new brake assembly fitted.
The wheels turn in opposite directions, because the drive is through the differential unit in the rear axle. Even a car will do this if the driving axle is raised in the air.
I have also had a few cases of stuck motor brushes in these machines, but from your description, I would say it is the brake assembly.
Good luck. Neil.

Testimonial: "It was a frozen brake. I took the brake to pieces,a lot of little springs spacers indent springs and rollers jumped out. Cleaned all components and spent a few hours figuring it out for re assembly. Working fine now . Thanks for your prompt and accurate reply. PeterR"
Since these are special made electric motors, you are going to have to go back to the dealer that sold you the machine and have them order the parts (brushes) for you. The PDF file for these scooters are found at:
page 6 will give you the parts number.
If you are mechanically handy(I suppose so as you intend to replace brushes), then you may want to try a maintenance trick first of all. Generally these brushes are are not used up in a DC motor, but fail due to the carbon build up on the armanture of the motor shaft or the wear of the brushes have become so concave that they are making only slight contact on the armanture. If you can, pull the end off of the motor and lightly clean the armanture contact. Clean with some alcohol. Then examine the concave of the brushes, and using an emery board file the points of the arc in the brushes so that you change the deepness of the arc, bringing the center closer to the contact. re-assemble and test.

What you got to do is what we call "chase the voltage" First you will need a 24v circuit tester
You may also need a VOM meter only $9
The problem is 24volts is either not getting to the tiller head or you have a broken wire in the tiller head. Start at the headlight make sure its switched on. Use the circuit tester, put the clamp to ground, use the probe to find the 24volts, The hot side is the side wired in series with the switch. The tester will light up when it has voltage. Chase the wire back through the system. When you get to a cable or anywhere you can't see the wires use the VOM meter, disconnect the scooters batteries leaving the power switch on. Set the meter to read resistance scale high scale, short the probes together, zero the meter. Put one probe at the headlight the other probe at the connector you think the wire ends up at. Normally every wire is a different combination of colors like red; with a white stripe. Most of the time a wire ends up at a connector and the color code doesn't change. So if you are not getting continuity on any of the pins on the connector you know its got to go, you've isolated the open circuit too the tiler head. Here's a test you can run! Turn headlight on, power on for scooter, disconnect scooter battery, place one probe at head light. Disconnect tiller cable. Probe each pin, one of them hast to cause the meter to deflect to zero. If if doesn't the problem is in the tiller head. When working with little wires i like to use crochet needles. You can use the meter to check cables each pin in must have a pin out. If you don't get continuity between pins the cable is bad toss it.
