Cant figure out wether my rascal wheel chair has bad batteries or charger

The motor controller may be bad. If the battery charger is connected to the charge port , the scooter won't move even if the charger is not plugged into the wall.

Hi Chris,,,, Now lets get the silly question out of the way first, have you tried another charger ?

IS it a built in charger ?


Remember a bad charger == Bad batteries...

the lead that goes from the chagrer socket to the batteries via the controller are most likely adding resistance that the charger does not like ...

your problem is related to the overload breaker on the chair you need to figure out why the breaker is tripping either due to batteries going bad or the brushes in the motor need adjusting or replaced , also you need to check the automatic brake is releasing completly a dragging brake will cause the auto reset breaker to trip

Wall outlet bad? Charger not turned on/plugged in right? Something disconnected? Bad battery connection? Blown fuse in chair or charger? Bad battery or batteries?

I recommend the 5 amp Charger. Monster Scooter Parts have them.

it is posible the batteries are not installed with the right poles or there may be a short, but more lightly the charger is dud.

Neil wood, the Rascal 600 DOES use an on board charger. What signal is the white wire looking for to make the scooter move is the question. 28v?

Any 4 amp charger you can find will work to charge your batteries. Preferably find one that has an on/off switch on the charger. You should be able to find one on ebay a lot less than what the scooter repair store quoted you Check around your neighborhood someone might have a second charger that they are not using. Since Medicare will pay for a new chair every 5 years someone might have a extra charger laying around. Hope this helps you

moleman If the batteries are fully depleted then the on-board charger will not pick them up and charge them to full strength. It is not designed to charge very low batteries. If the batteries stayed fully depleted for a period of time you will have to replace both of them. You should never fully discharge your batteries. The battery level gauge on your chair should be used to determine when to charge if it is the red recharge overnite. Get into the habit of recharging overnite if you use the chair daily. Always store the chair fully charged and if not used weekly charge once a week. Never leave the charged plugged in more than 18 hours. The chair only operates on about a 5-6 volt range from about 21-26 volts. If you are in the red the voltage is down to about 20-21 volts. Hope this helps you

Bad Charger or bad batteres that all it can be Hope this Helps
