I had been looking around for a wiring diagram for my L&R Master Watch Cleaning machine, and found the ones here at the NAWCC. One is posted in this thread:

And a picture of the wiring, and other stuff, is posted in this thread:
L&R Master Watch Cleaning Machine Wiring Diagram
Mine is different. I didn't mind, because it works fine (I had to turn a new agitator shaft, and make a new brass thrust bushing for the motor). I cleaned it, repainted it... and yes, I do intend on grounding it. You see it is a very early model... one of the ones with the "milkshake" motor... I think it is a Hamilton Beach... before L&R started building them with more purpose-made motors. And that might be why my wiring is different...
Anyway, I didn't care, except that the agitator rotates counter clockwise (looking from the top). And that does not matter... and maybe it came from the factory like this... but it means the fluids are not driven DOWN into the watch basket (due to the design of the vanes), but pushed UP. So my first question is: Is that normal? I mean, maybe it is a false assumption I had, that the fluid WAS supposed to be forced down through the basket.
Anyway, I only had two wires coming from the motor... white and black. On the models with reversible motors, there are three wires: White, Black and Green. And the old L&R Master wiring diagram... which I copied to my own drawing, below... show this. I even opened my motor back up, to see if someone clipped a wire, making this a one-direction motor. Nope... I can see from the field and brush wiring, this was always wired this way. And the wire from the motor looks original, anyway, and is only white and black... no green in there. Here is a comparison of the two wiring's, with my schematic on the bottom:
So... I see no way to reverse the direction, unless I were to either rewire the motor, or install a bridge recifier and switch, and control the motor by reversing the polarity (I think this could be done, as I believe these motors are AC/DC).
One last thing: I do have the drilled out switch hole in the base casting of the unit, which is where the reversal switch usually goes on these. That is probably the one reason I thought this must have had the ability to change direction, out of the factory.
What do you all think? Does anyone here have an early machine, that is one direction only? And is that direction CCW? And does it matter? Thanks in advance... proto57.
