how do the 2 speed lower motors in the 700 leslie power on

[keyofgee]

I have a 700 leslie (given to me) I have removed the amp in it and just want it to use the speakers (upppers 6 x9) and 1 lower 6x9 alnico with 2 speed motor stack. My question is: there are two standard 110v plugs, one for each motor. When I have just the one plug connected to household current I have the fast motor running, then when I have both 110v motor connections plugged in, the bottom rotor switches to the chorale slow speed.</p>

Is this how its 2 speed motors works? Are you supposed to have both 110v electrical connectons plugged in for the slow speed to take over? Or should the slow speed operate with only the slow speed chorale motor plugged in? </p>

The reason I ask is because some times it works fine and other times it stops and needs a push to get going again. I took the motors out and oiled them last year and have only about 10 hrs on them since. I have adjusted the belt tension and that doesn't help.

There are two separate motors. There needs to be some sort of switching mechanism to insure that only one runs at a time. With two separate plugs you miss this. You could plug them in to switched outlets. Not a very practical solution. Typically there would be switches on the organ that control the rotor speed. Some re-wiring needs to be done.</P>

G'day Keyofgee!</p>

Only one motor is supposed to be hooked up at a time. Would you like the design which can give you remote switching?</p>

Kon Zissis sent me one such plan....</p>

The belt needs to be loose enough that the motor can still turn if you hold the drum/horn, so the belt slips, but it needs to be firm enough that it still turns.</p>

If that's not fixing it then you need to adjust the angle of the slow motor so that the pin engages properly with the rubber tyre.</p>

Let me see if I can dig that info out of a leslie manual........</p>

hmm, I can't find the passage just handy for me to post it up. Anyhow, you'll notice the slow motor is mounted on three bolts with a bunch of nuts to help it sit in the right position. If you adjust em too far one way they'll jam on the tyre and can't disengage, the other way(s!) the pin won't even come near the tyre.</p>

Fool about with that and you'll eventually get it right! Again, if it's too tight it'll stress both the motor and wear out the tyre quicker, there's a perfect spot which you'll figure after a bit of tinkering.</p>

Let me know how you get on!</p>
