Leslie 860, fast speed won’t stay on.

[Spiney1]

I have an 860 with a Combo Preamp III. Two issues. When switching to the fast speed, it starts to speed up, then a slight click, and it just goes back to slow. Also when the stop button is pressed, it doesn’t stop. Any ideas? Thanks.

Hello,

There may be a problem in the wiring.

You can refer to the diagramm.

There is a little chart called 'Control circuit voltage'
It indicates the connections to make on the 10-pin plug for controling the motors when the pedal is disconnected.
So you'll know if the problem is in the Leslie or elsewhere

But first , check the cable and the plug. Looking for short, cutted wire, broken pin...
