One of my wheelchair motors overheats and stops working
Hi Jim, As expected, the following is the email I received back from Invacare, Still, they managed to deduce "there seems to be sort of problem". So now I know!

Hi, thanks for responding. The problem with equipment for disabled people is that most manufacturers (understandably) assume people with disabilities can't do their own maintainence so only give operating instructions not manuals. I can do most things except walk and I cannot afford the large...- Roysmokie

Hi can anyone help. I use an electric wheelchair to get around and can only walk a few steps with a wheeled walker. Yesterday I went to my local out of town ASDA, a 1.5 mile trip approx through an alley/Public Footpath, I have done this many times before. This time I was about 3/4 of the way...- Roysmokie
