I have not started the  MA for about 6 months. I charged all threee batteries and the Remote Contoller. I get four bright lights on each battery and the controller however niether the MA or RC will start.

Thanks for your help.

Well maybe what I should have done was the correct procedure for starting. What a dummy! See what you forget after 6 months.
