| Subject: | 60A Buss fuse attached to baffling? |
9/4/2007
Hello George, You wrote: "I think you have it backwards, you are trying to
protect the battery."
I was under the impression that fuses and circuit breakers were primarily
intended to protect the wiring between some source of electrical supply and
a recipient device on that circuit.
The idea being that a short somewhere along that wiring could generate heat,
smoke, and possibly fire. The protective device (usually heat activated)
would open up in the case of excess electron flow because of the short and
prevent the generation of a dangerous amount of heat and the resultant smoke
and potential fire.
It has been written earlier that the huge amount of unwanted amps that could
flow in the alternator B lead in case of a short would be coming from the
battery and not the alternator. So in that sense maybe one is trying to
protect the battery from depleting itself as well as protecting the B lead
wiring in order to avoid smoke and fire.
Perhaps it is a semantic thing -- Bob Nuckolls would you care to comment?
Thanks.

PS: One may also speculate on just what wiring constitutes the B lead. Let's
say that you have an adequate sized wire that goes from the B lead terminal
on the back of the alternator through an appropriately large fuse to the
input terminal of the starter contactor or relay. Also connected to that
starter contactor input terminal is a very large sized unfused wire, say AWG
2, going to the battery plus terminal some distance away.
What portion of the total enroute wiring connection between the alternator B
terminal and the battery plus terminal is considered the B lead?

I would not put it on the shaking rattling Lycoming. It may take it
but your do add fatigue to anything vibrating, although based in
the above, its a moot point, protect the battery and put the 60 amp
fuse on the firewall. George

| Subject: | Transponder constantly replies |
Hello,
I have an older transponder that seems to constantly generate replies
while airborne(solid light almost all the time). ATC reports it is
working great, but I think it is causing issues with a traffic scope
I have installled. Others report their transponder reacts the same
way, but more tell me they only get a reply on a sweep. I am
wondering if a bad antenna cable or connector could cause this?
Other thoughts welcome.

Mine (Garmin 320A) does that whenever the left Pmag is on ship's battery
power but not when it's in self-powered mode. Took me forever to figure out
what the deal was. I usually get normal function reports from ATC. I'll be
interested to see the consensus as to the likely cause of this behavior.

I haven't posted in quite a while because I have been uber-busy with my
electric drag bike (instead of building my RV-7).
For those that are interested in the latest battery technology, you
might enjoy watching "Green Wheels" on VOOM HD (also Equator HD) on the
Dish Network at 10 PM EST.*
