If it is coming from your motors, it could be very bad. i.e. motor replacement. Sometimes on the side of those motors there is a black plastic cap about the size of a quarter or half dollar, those fall out sometimes and allow gearbox grease to come out. This should`nt be confused with your motor brush caps which are about the size of a pea and have a small **** in them for a screwdriver.DO NOT TAKE THESE OUT. If the large cap has come out just stick it back in. If you can`t find it you`ll ned to call a dealer to get the part replaced. If you can still find no prob,your probably going to have to go to a dealer.
SOURCE: How do I charge My Pronto M51 motorized wheelchair?
Margie, Yes you may charge it overnight. If you use it everyday,charge it every night. Once the charger senses 24 volts it stops sending a charge,so they cannot be overcharged. I suggest when you go to bed put on the charger and unplug it when you get up in the morning.

Three lights flashing on your chair indicate a left motor fault. Make sure that all of the connections inside the shroud are tight by physically testing them. If all of the connections are good, and the fuses are good, then it's time for a trip to an authorized repair facility. Here is a link to the M51 owners manual if you haven't one. Page 24 has the fault code guide.

The controller monitors all of the functions on the chair, brakes, motors, joystick, charger etc. The three flash fault indicates an "open" circuit. Open, like a switch or blown fuse is open, or a wire is cut or burned in half, or a connector is unconnected, or partially connected. The latter is what you are hoping for. Wires burned in half is the usual cause for a motor fault, and with powerchairs, is usually the result of the chair getting stuck in or against something it can't get out of and the operator over-amping the motors. Motors do, just go bad sometimes, for no reason. Very rarerly, however.
You can also check the brushes on the motor too. There's two quarter-sized black plastic screw-plugs on the ends of the motor opposite each other. Unscrew them and examine the brushes. The springy coils should be springy. Overheating can cause them to be brittle, or even burned in two. Check the lench of the brush, the dark rectangular cube at the end of the springs. It should be curved and polished at the end, and a little over a half-inch long. If it is near a 1/4 inch, it needs replaced, or if there is any evidence of overheating, replace. Good luck.
