Question about NRS Hoveround MPV 5 - Used Power Wheelchair
Wheelchair is placed on charger at night. In morning, charger shows green, ride wheel chair for 10-15 min and red flashing light on controller shows need charging again. New batteries and controller 6 months ago. Any suggestions on what to look for. also fuses checked.
Most of the time it may be the batteries at fault. One more thing to try is charging the chair with the Joystick on all night 10-14 hours uninterrupted charging. Your chair may suffer from current roll back. There is a circuit in your system that has to be reset by the long charge cycle to reset it. I did not make this up. it occurs when the motors over heat or have a a large current draw. the chair will operate normally for ten maybe even twenty mins. then suddenly drop down to 2 flashing red lights.

Firstly, it is bad news to use an extension cord with the charger as it can get very hot. It will sometimes take 8-12 hours to get a full charge on the batteries. If the light does not go to green on the charger, the batteries may be damaged and not able to take a charge. This is especially true if the Power chair was stored after your father in law died; the gel in the batteries may have gone solid. The lights on the controller will go left to right then back if the charger is connected properly.
The brake release knobs both need to be in the UP/DRIVE position for the motors to engage.

After you changed the batteries, did the power chair sit unused for several weeks? It sounds more like a battery or fuse issue than a charger issue. If there are blinking lights when you try to turn the power chair on (not while attached to the charger), or it comes on then goes back off by itself quickly, there may be something else going on.
1- The green light on the charger is telling you that the batteries are not accepting any more power, either they are fully charged or they have oxidized/gone solid from sitting without being put on the charger for too long.
2-The scrolling lights on the controller when the charger is plugged in just confirms that the chair is connected to the charger, so it sounds like everything is connected properly and working. The horn will work fine when it is attached to the charger as it is getting power from the wall outlet.
3- If it was a fuse issue, the lights would not come on at all when the charger is NOT attached, even after the battery has been fully charged, which is what it sounds like is going on. The fuses can blow if you operate the chair on a slick surface or one of the drive tires spin out. The batteries will be fully charged but because the circuit is not complete, the chair will not power on.
I recommend checking the fuses and changing them if necessary. You are in luck because this is a relatively easy and inexpensive fix as they are standard automotive fuses found at any auto parts store or even Walmart for around $2 each (you need 2). The fuses are located inside the gray battery covers under the seat, attached to the leads connected to the battery cables. The straps holding the covers on the batteries are tight, you may want to use a flat head screwdriver to help release the clips. While you are down there, inspect the tread on the tires, if it is worn or slick it may need to be replaced for safety.
I hope this information is helpful to you- good luck!
