Red light flasheswhen on. 4times turn off - Pride Jazzy 1103 Ultra Standard Power Chair

This flash code is indicating that the right motor has a bad connection. It rarely is the case that the cable leading from the motor to the controller comes loose...it usually is the case that the motor has overheated and burned out a winding that makes it....toast, unfortunately. This can occur from getting stuck in the mud, sand or getting the chair trapped in a doorway, for instance, and trying to drive it against strong resistance. Also, I should add, that sometimes the controller "lies", and it might be the left motor. Swap the cable from left to right and right to left and turn on the chair and see how many flashes. If is shows three, then the right motor is probably shot. Also, and it happens a lot, if the controller(the box that the cables run into)has been damaged somehow, it may be giving you a false fault code. You have to have a known good motor to plug into the right motor connection, fire up the chair and see if that clears the fault. Either way, it is not a cheap, easy fix. Sorry for your problems.
