Re: 142 leslie stuck on high

Gregg,

As far as the Leslie problem goes; I've encountered this a few times.  If
you've confirmed that the relay is working, replace the .1 uf/600 volt caps
that are wired across the motors' AC sockets.  After time, these tend to go
bad and end up shorting the relay's terminals, essentially cloing the
switch.  For the Kruger, check the pedal switch contacts...sounds like one
of them is bent and making contact.  Hope this helps!
