Any ideas? Faulty EQ2 Skywatcher RA drive

[broony]

Was looking forward to going out tonight after doing my first webcam observation last night and getting my first ever picture of Jupiter (still smiling)

Anyway, the drive ran out of batteries (I presumed), bu I replaced batteries with fresh ones. The power supply is pushing out 6.7 volts.

BUT as soon as I plug the motor cable from the power supply to the motor....the power light briefly flashes red , then goes off, and the drive doesn't work. Sounds like the drive unit is faulty rather than the power supply. any ideas what might be wrong or if I can fix by dismantling (i like dismantling things).

thanks in advance. Its made me sad that I cant do a decent webcam of Jupiter without the drive as it moves too fast
