Is there a practical application for this?

I believe that the 12V source will try to charge the 6V source,
overcharging the 6V battery if a diode is not present.

Yes.
All else being equal if you connect both a 12V and a 6V source in
parallel to a single load without any other intervening components then
the 12V source will supply the load and the 6V source will sit idly by
doing nothing.

Subject: | Re: When are diodes needed? |
Yes absolutely ! (assuming the sources are batteries. If they are diode iso
lated power supplies (alternators) the original statement stands)
I wasn't suggesting that this was a practical thing to do. Mearly that the
higher voltage source will supply the load. Normally we would be talking pa
ralleled batteries or a battery and an alternator. In either case the highe
r voltage source will supply the load. All else being equal=2C the lower vo
ltage source will be idle until the system voltage sags to equal the lower.
(even this is an oversimplification=2C but hopefully gets the idea across.
The higher of two paralleled differing voltages will be supplying the load
s=2C including attempting to raise the lower voltage source. That's the bas
is of how a charging system works)

Yes.

Should work in aircraft as well... Keep earths negative energy from
pulling the aircraft to the ground when not intended.

Yes, I was away Jan/Feb.
I'll be back here much more after Easter as Gary will be here then, so
May/June would be a good time - call or text me?
