thanks for the reply. considering all the warnings i've read regarding blown ACC's , i disconnected it last nite. Luckily, when i tested it with a power supply it drew no current so i suspect that the brushes are gone or the motor windings are open. as far as being a purist... I AM. so i'll see if i can find a cheap replacement. the local parts wholesaler as one for $55. maybe i can repair it for less.
