Thank you, Bud.
For anyone interested, attached is the modification that I will do to the
wiring of my installation, OK'd by Electronics International.
I will use a 12 volt relay with two contact sets. In normal operation, the
relay is not energized. The white wires from both the Feed and the Return
flow transducers are connected to the Differential module as per the
original wiring diagram. Net flow = consumption is displayed on the
instrument.
When I energize the relay, the white wire connection from the Feed
transducer is cut, and the white wire from the Return transducer is
connected to the Feed white wire going up to the Differential module. The
display now shows the return flow.
I will use a momentary pushbutton switch (closed contacts when pushed and
held in the "in" position) so that I do not risk leaving the relay
energized. No chance of upsetting the totalizer function in this way.
As mentioned, I will post some return flow readings on this List when my
flying season begins later in the spring.
Regards,
Svein
