I have replaced joystick, batteries, motors and the chair still losing lights will go about 1/4 mile and loses all green lights with in 1/2 mile loses all the yellow lights, drove on 1 flashing light for 30 minutes and didn't notice any speed reduction so I parked it turned off and turned it back on and all lights are on except one.

The rippling lights on your Drive Seren mobility chair, followed by the chair stopping and the power sign coming on, could be indicating a problem with the battery or the motor. Here are a few steps you can take to troubleshoot the issue:

1. Check the battery connections: Make sure the battery connections are clean and tight. Loose or corroded connections can cause power issues.
2. Test the battery: Use a multimeter to test the battery voltage. If the voltage is low, try charging the battery. If the battery won't hold a charge or is more than two years old, it may need to be replaced.
3. Check the motor: Check the motor connections for looseness or corrosion. Test the motor by turning the chair on and listening for any unusual noises or vibrations. If the motor is malfunctioning, it may need to be replaced.
4. Check the joystick: Make sure the joystick is clean and free from obstructions. Test the joystick by moving it in all directions to see if it responds properly. If the joystick is faulty, it may need to be replaced.

If these troubleshooting steps do not resolve the issue, it may be necessary to contact a mobility equipment repair technician for further assistance.

The M51 could have the motor clutch levers in the free wheel/push mode and the joystick will not blink if this is the case. Make sure that the chair cannot be pushed. If it can be pushed it means it is in free wheel and you need to lock the motors in gear.

If it is in gear and the joysticks green light does not change color or blink it could be that the joystick is bad. When nothing happens and the lights don't blink when you push the joystick knob the chairs controller basically isn't recognizing the joystick movement.
Time to have the joystick repaired or more. Have a technician look at it.

Have that guy thoroughly test your batteries and connections. In fact, have him replace the batteries.

Angel the charger light should only turn green when the chair is fully charged. If you know the chair isn't fully charged then there is a problem with the charging system. if the circuit board in the joystick got wet then that is a serious problem. If you have a voltmeter you can check the battery voltage thru the charging port located under the front of your joystick Set the meter to 200 volts dc and plug the leads into the 2 outter holes of the charger port. Fully charged you should read 27-30 volts if you aren't getting any reading then the batteries are completly dead or there is a problem with the charging circuit (the reason you are getting a green light on the charger) The joystick will have to be replaced sorry If Medicare paid for your chair then they will pay 80% of the repair costs to get your chair working again If they did contact Roadrunner Mobility @ 1-800-467-2668 to get it fixed thru Medicare Hope this helps

Why do you want to byass the power module? the lights you mention are ok just need to charge your batteries a little longer to get all the green lights on. If you changed the controller, plug all your cables into the new one and try the chair it should work like its supposed to. I really don't know what specific problem you have. Is the chair not working when you tun on the joystick? are you getting any flashing lights on the joystick? are your freewheel levers in the drive position? Let me know something morwe specific Thanks

According to my 1170 manual the flashing lights are error codes. 1 red = low batt., 2 red = left motor disconnected, 3 red = Left motor wiring fault, 4 yellow = Right motor disconnected, 5 yellow = right motor wiring fault, 6 yellow = Inhibit active, 7 yellow =possible joystick fault, 8 green = possible controller fault, 9 green = Solenoid brake fault, 10 green = high batt. voltage

The green lights will gradually go away as your battery is being used, this is completely normal. You batteries should last for around 5-10 miles of use. If you find that your battery light falls into the red after only 2-3 hours of use and you have been charging the batteries every night for at least 8-10 hours, contact your manufacturer for service.

Romp, Did you check the freewheel levers chair will not move if you are in freewheel. Levers are in front next to seat posts and need to be facing forward. If you are not in freewheel then check the number of lights you have on on the joystick and that they aren't flashing. Also check that your speed control is not on the lowest setting even with some charge a slow speed setting will not let the chair move. Now by some charge you mean lights in the green on the joystick? If the lights aren't flashing then I'm kinda unsure other than even with some charge the batteries don't have enuf current to drive the motors and need to be replaced Hoe this helps

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

Are you sure the FREELEVER is in the right position ? , to test try to push the scooter ?

Battery Low ?
