Will do, but without the beer! I have not tried your controller on a
discharged battery. I guess I have been moved by others not in the know. 
Thanks, Raymon Ellis

I still think using a bypass is not a good idea.
Do an experiment: Mow the lawn. return to the garage and plug in the 
tractor

using my controller, but not the bypass timer. Get a beer and sit by the 
tractor. You will hear the charger hum. After a while (typically 4 min) 
you 
might hear it stop humming for half a second or so and start up again. 
Keep 
sitting and nursing the beer. After another 4 min or so, you might hear it 
do it again. After 20 min, the timeouts will be longer. After a few hours 
it

will be off most of the time, and only occasionally on for a 4 min cycle. 
So

the conclusion would be that when the batteries are low, the charger is on 
almost continually. When they are fairly well charged, the charger is only 
on intermittently. So what use is the bypass timer?

This is for those who have experienced timer problems and are looking for a
simpler charger setup. Michael J. Banks wrote that he fixed his timer after
opening it and all the switch parts fell out in his hand. He is a champion
and I salute him. I took mine apart and found it impossible to reassemble.
Today a standard 12 hour auto shut-off mechanical timer was installed to
straddles the newly installed Landis controller to override the Landis when
the batteries are very low. This may be the answer for anyone willing to
risk it. An in-line fuse and single pole switch was inserted in the red 
wire
to the Landis to stop power while the mechanical timer is in control
although this may not be necessary. When the timer was first turned on this
morning the power meter showed a current draw of slightly over 8 amps. 
After
a few minutes the current reduced to 4.6 amps. All seems well now, but the
big test will come later this week when we mow the lawn and run down the
batteries. The ability to charge 6 or 8 hours with the mechanical timer
followed by the Landis method for unattended surveillance ought to be just
what the doctor ordered. The power usage record should prove the practical
advantages of the setup. Maybe.
