[GreenKeys] ASR 33 motor buzzing

[teletypeparts at comcast.net]

There is no start capacitor on the 814 motors, just the start relay.

I don’t think I have one. I’ve seen pictures of motors that had it, in a little holder to the left of the starter relay. There is nothing there and no provision for wiring. I have two caps where the PSU is.. one near that big flat resistor, and then another behind the PCB with several resistors and caps on it. I could be wrong but I cannot find any other around.

Brad, 





You may simply have a bad motor run capacitor. Check that there is one (I dont know but suspect there is) and replace it. If it is open (the likely failure mode) then the motor won't run.

Okay so I think I may have a dead motor on my hands. When I power my ASR on I hear a loud buzzing, and I can hear and feel it coming from the main motor. However if I manually turn the motor shaft (clockwise), everything in the Teletype seems to move as it should, it’s not seized. After a while it will blow the 2A fuse nearby. 



Would that about be the right diagnosis? Can the motors be rebuilt? 



If anyone else has any other suggestions on stuff I can try, I’d be most appreciative.
