was greater than 13.8 volts. DC/
DC converter is on. Tractor must
be running and alternator good
to achieve 13.8 volts. A batteries
surface charge cannot reach this
value.
Note: The turn on voltage is 13.2
volts after 5 mins or 13.8 volts
immediately. Reason is that if in
Dual Pole in Parallel state, the
Select input is now connected to
liftgate batteries via the dual pole
cables. If the liftgate batteries had
been charging using the DC/DC
converter, then that voltage could
be above 13.2 volts.

drops below 13.8 volts. DC/DC
converter is on for 1 hour. Every
two minutes the controller turns off
the DC/DC converter so there is
no current flow (no voltage drop)
and measures the battery voltage
on the tractor batteries. If over
12.4 volts, the controller turns on
for another two minutes. This will
repeat until 60 minutes has expired
or the battery voltage drops below
12.4 volts.
