spectra tone wiring

[RD78744]

Hi all. I'm new here & I need some help. I have a spectra tone (Leslie type of speaker) with 2 motors that came out of a Wurlitzer organ. When plugged in it goes directly to the fast motor. There is a wiring harness controlling the motors tied to a plug with 9 wires in it--I suppose this went to switches on the organ. How do I wire it to switch back/forth from slow to fast? Does anyone know where I can find Spectra tone schematics? Any help appreciated.

spectra tone switching.....

hi all. Ok a little playing with the solenoid on the spectra tone slow motor reveals that somewhere around 30vdc @350ma is where it will switch back and forth. I've also found that this really strains the transformer as I've already burned one up so I'll probably go to a 30vdc power supply with a higher current rating.
