Atlas turntable motor #301

[pjjkg]

Hi, Any thoughts on an Atlas 301 turntable motor that won't work?

Was never used as grease "dollops" had never been squished into gears and both inner and outer boxes pristine.  No sign of wear/use at all anywhere.

Attached to power source that had been checked and working.  

Thanks

Has the motor been removed from the turntable while you were trying to power it? With the motor removed, try turning the turntable shaft by hand. It should turn easily. I have photos of the Atlas turntable paper work I can post if you do not have the paper work. It is pretty simple. Two terminals right on the motor housing for power and two terminals on the turntable for track power.

I think you can see the motor armature with the plastic cover removed. Try rotating the armature by hand.

Hi,

Motor was NOT connected to turntable. Gears and shaft move easily.

Have paperwork  but thanks.

The motor might have a stuck brush that's not contacting the armature. Does it hum or anything? Does it register any current draw if you hook a meter to it?

No humming.

Will get my VOM tomorrow at work and check.

Thanks to all.

Don't overlook the obvious: check the wires between the terminal screws and the motor, as well as checking the terminals for corrosion.

Tom, You were right on. One of the wire connections at the motor was very tenuous. Tightened it up and heard the motor hum.  VERY LOUDLY as noted on other wites re this Atlas product.

Thanks a lot

I've been doing electrical/electronic troubleshooting for more years than I care to admit. The best advice I can give is: Start at the beginning.
