I would expect very little current flow and no need for added resistance
between the two paralleled batteries. In a similar situation my dead
battery was already high resistance. I could set the charge voltage most
anywhere and no current would flow into the dead battery. Sometimes if a
dead battery is held at normal voltage for awhile though it will begin
to respond and slowly start to accept a charge. I think that is what you
are trying to achieve. I've never seen significant current flow between
two paralleled batteries although it is probably possible with multiple
cells that are truly shorted.
Slightly off topic. I find a power supply with limited current to be
much more useful than a "bench" battery unless you are trying to spin a
starter motor or something. The battery tends to smoke things when there
is a short or a problem with the item under test. I use a homemade
adjustable current limited power supply but prices are pretty reasonable
for such things now.

[quote="piavis(at)comcast.net"]I recently had the aircraft down for conditional
inspection and after about 6 weeks started the aircraft, and when the alternator
was brought on-line, the field breaker is now popping as soon as the alternator
switch is closed.

Dont know if I am reading this correctly. Could you be saying that this problem
occurred immediately after the condition inspection? If so, it could be a LO-Tech
problem, like what was touched / swapped / painted (insulated) / or removed
during the inspection.

Ken makes an interesting point about current-limited power supplies vs
batteries for bench testing.
I have both, and I find that under some conditions the current-limiting can
nuisance trip when used w/ high-inrush loads.
If you are concerned about letting the magic smoke out of some device then
put a fuse in the output of your bench-test battery, you get the best of
both worlds easy & cheap.

C=99mon, Old Bob, surely your memory is better than that.
While the 92nd Congress was indeed controlled by the Democrats, most
folks wouldn=99t refer to Nixon as a liberal, but he did sign the
bill mandating ELTs. Of course, he also gave us the 55 MPH speed limit
and wage and price controls.
If you really want to avoid the mandate, fly only single seat aircraft.

Good Afternoon Dee,
It is obvious that I have not presented the point in a way that you can
understand my feelings. It should be a decision we make. NOT a forced
solution.
We as, individuals, should be able to choose what method we want to use
to maintain contact with the rest of the world.
I can do at least as good a job of providing guidance for recovery of my
aircraft as do the air carriers. I might elect to fly IFR at all times
or I may just decide that I do not want any help if I should fail to get
where I am going.
More likely, I would carry a PLB in areas that would be difficult and
nothing at all in flat land Mid America.
Lots of possibilities.
Long before the rules were forced upon us, I made a practice of carrying
a portable VHF communication unit (Remember the Bayside?) and keeping a
current IFR chart on board that would let me know what frequency would
be monitored by aircraft in the area.
My recollection is that IFR flight was NOT mandatory for air carrier
aircraft at the time the ELT was foisted upon us. It was the decision of
a liberal congress critter that forced the issue. Not the FAA or the
aviation industry.
The idea is one of personal choice.
Happy Skies,
Old Bob

Bob,
As I understand it, the reason commercial airliners don't have ELTs is
they are always in contact with ATC and on IFR flight plans. If they
crash, there is no question of locating them unlike a GA airplane which
can choose to fly VFR with no flight plan and not in touch with ATC.

Ray,
On my Murphy Super Rebel, I used some =BD PEX tubing I
had.
It weighed roughly the same as the alternatives, and I like the smooth
walls
for pulling wires vs. the flexible conduit. It also had a higher
temperature spec than the flexible conduit. I attached it to the ribs
with
aircraft grade zip ties. To keep the ribs from cutting into the tubing,
I
purchased some door edge guard material from a local auto shop. It came
in
36=94 strips and I cut it up so the tubing and the back of the zip tie
were
pulled against the edge guard vs. a sharp rib edge. I anchored the
tubing
to the root rib with a PVC Pex coupling that I cut in half. That gave
me a
flange on the outside and the pex ribs on the inside. I used proseal to
mate it and a clamp, then removed the clamp when the proseal dried.

Hi Ray,
I used 5/8-inch OD HDPE tubing from McMaster-Carr (www.mcmaster.com)
through
the lightening holes in the leading-edge ribs of my Murphy Rebel Elite.
I
supported the conduit at every other rib with Adel clamps. I haven't
installed the wings yet, nor have I pulled any wires, so I can't give

EMT (thin wall) conduit is still heavy - a little
here a little there adds up. Ya, Plex isn't bad
- light. One I used on another UL type aircraft
is drip irrigation tubing. Another factor is
what burns and what doesn't, might be a factor to consider for fire spread.

Thanks to all who wrote. Fire is a concern with some of the plastic
conduit mentioned. I'm concerned about just pulling wire and leaving it
loose to rub on wing ribs, even with grommets. I'm thinking some very
thin wall al, if I can find it. If I could find some fire resistant
composite tubing, I'd look at it but I think it might be too expensive.
Thanks again.

I wouldn't mind if it were optional, but then for those who don't carry
one, I don't want to pay taxes to go look for you.
The ELT requirement started when a Congresscritter disappeared in his light
plane in Alaska and the military spent a lot of time and money looking for
him. Never did find him. You can say they're worthless all you want (ELTs,
I mean) but since the government spends money to look for you they have the
right to force you to make their job easier.

I didn't care about fire resistance or non-toxic-smokeproof plastic for the
wing conduit. Just used the thinnest-wall irrigation conduit I could find
at the local Ace Hardware and Aviation Supply store.
Now the fuselage, that's different. I used split-loom and spiral wrap, both
fire-resistant, smoke proof, etc.
