Hi. Your problem will be either the free-wheel lever is in the wrong position, or the motor has a stuck or worn carbon brush.
Good luck. Neil.

Wrench flashes yellow 3 times and repeats itself on pronto m51


On the Invacare M51 a flash code of 3 usually indicates M1 left motor fault. Check the motor connections and Anderson pins in the connector housings. The motor can be tested using a voltmeter. The motor windings should read about .4 ohms and the brake about 40 to 60 ohms. Hope this helps.

Have Pronto M51. I got a left motor fault, and replaced the motor. I still get the left motor fault, and what I have checked with a meter checks okay from the info I can find. What do I do now?


Take the motor connection and interchange the right motor with the left one. if the problem moves to the right motor then it is the motor or its wiring. If it does not move when changing the the connections then it is a problem in the controller. hope this helps.

Repair light blinks 3 times


3 blinks is a right motor fault on a Pronto M51. Check that the motor plug has not come unplugged from the main control box or that any of the wires have been broken, cut or pulled out of the right motor.

All lights blink together at a 6 blink intervals


claxtonbrent That is the error code for a bad right brake and it will have to be replaced. There is no quick fix for this problem. It requires a new brake and I'm not sure if you can replace just the brake Usually when I get this and Medicare is paying for the repair I have to order a right motor/gearbox assembly. you can contact Invacare @ 1-800-333-6900 ask for M51 tech support and ask if you can replace just the brake Hope this helps

Model 51sctrstr. controler blinks 4 times. whats it telling me?


F350 The 4 flashes is a error code on the M51 for a right motor problem. If you can check the connections at the controller located behind the front cover thats behind the footrest. If the connection looks good and hasn't come unplugged then you have a bad motor and it will have to be replaced. Unfortunately with the M51, you have to replace the whole motor/gearbox assembly. If Medicare paid for your chair then they will pay for most of the repair costs. You can contact Repair Xpress @ 1-877-581-3733 or Roadrunner Mobility @ 1-800-467-2668 for repair services. Hope this helps you

The charger is blinking green indicating that the output is not connected but I cannot see any disconnected wires


The disconnected wire may be inside the junction box inside the motor assembly, or on the leads connected to the battery and fuses. If all of those check OK, contact Invacare for service. If your insurance purchased the power chair for you, they will most likely cover the cost of any repairs.
Good luck!

Blinking charge light on Invacare Zoom 300 scooter


Can you try another charger ?

Is it a onboard charger ? if so they do go wrong, Are they supply MK batteries ?

Check the leads from the charger connection socket to the motor controller board.

Won't move pronto m51


Three lights flashing on your chair indicate a left motor fault. Make sure that all of the connections inside the shroud are tight by physically testing them. If all of the connections are good, and the fuses are good, then it's time for a trip to an authorized repair facility. Here is a link to the M51 owners manual if you haven't one. Page 24 has the fault code guide.
http://www.invacare.com/doc_files/1125085.pdf

The controller monitors all of the functions on the chair, brakes, motors, joystick, charger etc. The three flash fault indicates an "open" circuit. Open, like a switch or blown fuse is open, or a wire is cut or burned in half, or a connector is unconnected, or partially connected. The latter is what you are hoping for. Wires burned in half is the usual cause for a motor fault, and with powerchairs, is usually the result of the chair getting stuck in or against something it can't get out of and the operator over-amping the motors. Motors do, just go bad sometimes, for no reason. Very rarerly, however.

You can also check the brushes on the motor too. There's two quarter-sized black plastic screw-plugs on the ends of the motor opposite each other. Unscrew them and examine the brushes. The springy coils should be springy. Overheating can cause them to be brittle, or even burned in two. Check the lench of the brush, the dark rectangular cube at the end of the springs. It should be curved and polished at the end, and a little over a half-inch long. If it is near a 1/4 inch, it needs replaced, or if there is any evidence of overheating, replace. Good luck.
