Your power supply has probably failed. can you try another HP power supply or use a multimeter? Listen to the power supply and if it is making a chirping sound then it needs to be replaced.

Invacare what does it mean when light on charger continually blinks red when charging, It wont move


The red light is the power light and if the red light is blinking the charger is bad or the wiring is bad on the chair or the batteries are bad. Usually it's the charger.

No power charger does not light up


Hi David,

Thank you for reaching out. I am sorry to hear you are having difficulty with your DC35. Your charger light should illuminate, even if it is only for a moment, when you initially connect your machine to the charger. In light of the fact that your charger does not illuminate part replacement may be necessary to resolve this issue. We are happy to help with this. Please call our Helpline at your earliest convenience for assistance.

Best wishes,

Jessica

My Hoveround MPV5 batteries will not charge, do you think it is a battery problem or a charger problem?


If you plug the charger into the wall, turn on the power switch and the light comes on, the charger should be working properly. Here is a way to test it-
Attach the charger that came with the power chair to the power chair controller firmly and turn the power chair on, while the charger is running. What should happen:the lights on the controller will scroll back and forth. If this does NOT happen and you can confirm the charger is turned on, the charger handle is fully seated inside the controller receptacle and the wall outlet has power, then the charger may have a problem and needs to be replaced.

If the charger is OK, then there may be a problem with the batteries. Here are some sypmtoms:
1-You connect the charger but the light on the charger never goes red, it just stays green.
2-You connect the charger but the light goes from red to green VERY fast.
3-The charger light goes from red to green but when you disconnect the charger and press the power button on the controller, you only have one flashing red light, or the batteries drain within just a few minutes of use.
4-The power chair has been stored or sitting idle for several months.
5- The power chair has been connected to the charger 24-7 for several months.
Any of the above examples indicates that the batteries are oxidized or damaged and will most likely need to be replaced. The MPV5 takes two, U1 12 volt 33 amp batteries which can be purchased at any battery warehouse store like Interstate Batteries or Batteries Plus.
Good luck!

When turning power it makes a clicking sound but does not power up. battery charger has a red and green light on. When plugged in and turned on it flashes 8 times. I checked the power control connection,...


The chair will not move if the charger is plugged in. The flashes are normal with the charger plugged into the chair. The lights on the charger mean that the batteries have been fully charged. Red and yellow lights mean charging. After you unplug the charger from the chair (if off-baord charger, turn charger off or unplug from the wall) then unplug from joystick. after plug is removed from joystick press the on button and all the battery lights should be lit and when you move the joystick forward you will hear the electric bake release and the chair should move forward etc Hope this helps

Unit will not power on. Light on the charger does


if the light is not on, on the charger, check the fuse in the end of the car charger...the tip unscrews and there is a tiny fuse just under the tip.

if thats ok, check the fuse to the outlet you are using in your car.


if the light comes on the charger and it still wont charge, let me know and i can help you fix it.

TomTom will not charge with car charger


Mine does the same, the light comes on on the charger, but not on the TomTom unit itself. There is clearly a loose connection in the cable somewhere as you can twist the flex and make it work, although this is not very reliable.

I just use a USB charger from an old phone instead.
