Fostex 280 motor defective? Tips on external testing wanted.

The capstan motor doesn't seem to be doing anything. I tested it with play engaged with all possible combinations of the micro switches, both pressed, both depressed, one pressed one depressed and vice versa. I would like to test it with an external power source but I don't know how to considering the A and B pads. I tried to switch the cables over from the fast forward motor (10 volts DC). And that did nothing. See pictures below for a reference.

Wherever you can find one. Fostex parts and service support wasn't the best. This looks like a Mabuchi DC motor, commonly used on many cassette decks of the era. Hopefully you can find a good motor to replace yours.

It is EG-530KD-2B 1600/3200rpm. Not a common motor. I would try to disassemble it and restore. If it is not fried, brushes could be replaced (but I am not sure) with brushes from another Mabuchi of 530 series what can be found new on ebay very cheap.
