Thanks for the response Pagan, I appreciate that you should probably 
be too busy to deal with this :-)

I'll have them check but I believe that the exercise timer is 
defeated.  exercise period days = 0

I'll send you the diagram off list.  the inverter operates the 
generator by connecting it to a dummy load (and AC2) so as to trigger 
the automatic start circuit in the generator.  Unless the inverter 
calls for a gen start, the gen is disconnected from everything and 
will not start.

It's an old Lister start-o-matic (very common type here).  It starts 
up immediately it senses a load and stops immediately when the load 
is removed.
