wow, i guess im about 4 years late with this reply ;-p... im glad my post has helped out some of you and thanks for the replies i actually still have the old motor and control circuit and now i know what part to buy to fix it so i can have it as a spare

. Luckily the motor i spend $1000 on is still running fine, i wish i knew about that part number earlier but what can you do, you live and you learn its good to see this info has helped others save some money
