Marilyn Not having worked on many M6 chairs in a long time I would venture that you have a left motor error indicated by the 3 flashes however since you don't have a indication of full power you might have a battery problem because a low battery can cause the chair to flash also. If you can get someone with a digital voltmeter to measure the voltage at the charger port on the joystick it will let you elimitate the batteries as the problem. Place the voltmeter to 200 volts dc and plug the leads into the two outter holes in the charger port the reading should be 24-27+ volts if the batteries are fully charged. If you are not getting anything or a very low reading then that could be the problem. Replace both batteries with U1 batteries. After yo replace the batteries and charge them before use then turn the chair on and see if you are getting the smae flashes If you are then I suspect it is the left motor and it will need to be replaced,\. Hope this helps you
