Dont want to get into a political discussion, and as a European citizen I
agree that many of these regulations are way over the edge, but I must
object to your "shove it down America's throat" comment.
Europeans and other people around the world are experiencing America's
self-centered rules and regulations every day, from invasions on our privacy
(database searches through our private bank information by the CIA), stupid
security measures at our domestic airports because of US regulations,
privacy invasions with background searches for each flight, and ridiculous
impact on our businesses (Sarbanes-Oxley, DMCA). So when Americans are asked
to comply with world-wide regulations this has nothing to do with 'shoving
through your throat'. Besides, if it was such a big deal, the US would have
ignored the RoHS guidelines alltogether (Kyoto anyone?!?)

Real easy to solve Rob,
Better protection on your computers, do not allow flights to or from the U.S.,
do not allow U.S. products in your country, do not ship any of your products to
the U.S.
If there are any American Military bases in your country take them over, shut them
down and send our servicemen home. Then encourage all your neighboring countries
to do the same.
I am sure Russia and China will be happy to become your new best friends and certainly
they will be more than happy to help out if a time of great need ever
arises. Of course they will never try to impose any self centered rules upon you
and will never snoop through your databases.
Or maybe you could cozy up to Iran, they have oil to sell.
The French can always be counted on to lend a hand also.

I think you have it backwards, you are trying to protect the battery.
I would not put it on the shaking rattling Lycoming. It may take it

This discussion could become a complete fur ball very quickly. We
aren't going to solve all the world's political, environmental,
terrorism, etc problems here, as there are too many different
viewpoints, each of which is perceived as correct in the eyes of its
holder.
How about we all just agree to disagree on any non-AeroElectric
issues, and go back to subject areas that properly belong on this List.

Kevin,
I agree. First it is telephones, now it is geo politics. What's next? TV
shows?
And I can't even get a simple question answered concerning e/p mag wiring.

Political issues aside, the biggest problems we're looking at
with respect to RoHS compliance are the 100F higher flow temps
of present lead-free offerings. In days of yore, one was advised
to hold the lead wires of a solid state device with a pair of needle
nose pliers while soldering the joints . . . so as to preclude
damage to the fragile "chip" . . . nowadays, we run boards
chips and all through big ovens designed to flow little pads
of solder paste upon which each component sits. 63/37 PbSn
is the lowest temp product to date. The 100F jump in flow temps
for the new solders presents some big reliability issues
for components "cooked" at higher temperatures.
The lead free solders are not as resistant to cracking under
vibration and yes, there's the tin-whiskers. For the moment,
aviation is exempt from the lead-free push in Europe but it's
probably inevitable. It's been suggested that all future
devices assembled with 63/37 PbSn be fitted with warning
labels and return postage guaranteed back to the point of
origin. The idea is that when the device is ready for the
scrap heap, one simply drops it in the nearest mailbox and
the "problem child" is whisked back to its parents!
It would be interesting to bury a bunch of old TV sets
and come back in 20 years to do soil samples and see
just how far the problem material has migrated into
the soil. Even if we DID find noteworthy elevations of
lead, what is the significance of the finding? It's
not like this is a new thing. Aspen CO went through a
long ordeal with the EPA a few years ago. See:
http://www.dailymotion.com/video/xo2k0_are-we-scaring-ourselves-to-death-3_news
Folks in this part of the world decided to mount the great
battle through environmental regulation (not laws mind
you but requirements drafted by folks with no real
knowledge, understanding or accountability). In other
parts of the world, they've crafted restrictions against
commerce but the same quality of administrators are
tasked with the job of making us all "safe".
Whatever the outcomes, it's not going to be cheap,
the lives saved will be un-quantified, and the folks
writing/enforcing the regulations today will be retired
at 75% of base pay patting themselves on the back for
having "done a good job".
For me at least, I never miss a chance to stock
up on my favorite forms of 63/37 . . . and I'm not
planning to change over soon. The risk and expense
for not doing it are incalculable while the risks
for jumping on the band-wagon are real and
demonstrable.

Sounds like your ammeter is a bit big for the job and
it may be wired backwards too. Normally, one expects to see
a STRONG + reading while the battery is being replenished,
a near ZERO reading while the alternator is carrying ships
loads and the battery is charged, and a STRONG - reading
when the alternator is off and everything thing is turned
on. Your "slightly negative" observation while charging the
battery tells me it is too small and wired backwards.

Yeah, compared to the 1.5KW peak power demand on the
cable TV power supply, these are a hand-full of watts.
These are still a lot better than Seebeck effect devices
but one is still challenged to maximize temperature
differentials between hot and cold surfaces. The kerosene
lantern devices worked better if one sat next to it
and fanned the outside surface to provide forced air
cooling!

Subject: | how long for extra wiring to reach panel from wing? |
If it were me I would wait until the fuse is mostly together and the wings
are on for fitting. If you have the instruments etc installed it is easy to
feed the wires down to the fuse sides and coil them up until the wings go on
for good. It is easy to slide the wires through a conduit in the wings
rather than try to feed them up into the panel area. Hope this helps.
