I'm trying to locate a schematic diagram for the remote raising and 
lowering controls for an LM470 tower. the "up" feature works but the 
"down" does not, and the only way to lower the tower now is to use a 
screwdriver to hold in the big contactor inside the tower-mounted control box.

Any ideas where I could find that info now? This was a second-hand 
tower and the original owner no longer has any documentation for it.
==================================
I suspect that the Down Relay limit switch has failed, or the wiring to it.  
It is in the return leg (ground) of the down relay and if open the relay won't 
pull in.  Try locating that side of the relay and with a jumper wire bridge 
the leads going off to the Limit switch.
