Hi I have a electric wheel chair merits P313 two new batteries and joy stick having 2 of 6 middle lights blinking at fast rate.

Monster Scooter Part sells the controller for $400. Installation is straight forward once the controller is located under the shroud cover. Remove the 2 mounting bolts and unplug the wiring connectors. The Shark controller connectors are easily removed by a squeeze or pull back on the lock ring. Hope this helps.

have lights so not fuse blown
not much to these ..batteries .. controller .. electric motors
hard to mix up the positive and neg terminals
that is a two battery unit


check if the joystick controller or its cable is faulty

If the joystick turns completely off when you try to drive it means the batteries instantly are dropping voltage below the operating capabilities. I have also seen bad connections in the battery wiring harness cause the same thing.

Make sure the manual brake isn't down.

The number of lights that are blinking indicate what the problem is. Visit this site to locate the type on controller on your power chair and you will be able to see that the blinking lights mean:

Try to reset your manual brake release as this is a common problem.
If you continue to have a problem, contact your manufacturer or dealer for service. If your insurance purchased they power chair for you, they may also cover the cost of repairs.
Good luck!

Hi. You say that the lights blink? Do all the lights blink, or just some. If its just a few then it is probably a fault code. Count how many lights are flashing and let us know and I will be able to look it up. Do you have either of the motors in free-wheel. The brake units have small micro-switchs on them, and the controller will not operate in either switch is on. Also check all battery and motor connectors. Good luck. Neil.

It appears that there is no manual listed online, but I think that is because you are reading off the DL 5.21 from the controller and that is just the controller model which is made by an electronics company not Merits. The models start with 'P' and 'R'

Batteries are normally 2 x 12 volt 20 amp hour (AH) for the outdoor scooter type. Indoor wheelchairs take one.

It is not shutting off. You need to bring it to an expert for service. Your problem sounds like it is electronic, not mechanical.

To stop it from discharging you can disconnect the batteries. The batteries should be hooked up in series 24vdc not parallel 12vdc.

Just had this problem with my Guardian Aspire. They had to replace the electronic box with the joy stick. BIG BUCKS!
