Hello Group
Intuitively screwed down ground terminals seem so much more reliable is
there a reason the fast-on tabs are more popular?
Thanks

Fast-on Tabs are more reliable, and probably lighter. Automobiles don't
use screws to wires together, generally. The ground straps on automobiles
are often screwed or bolted, and they are often the weak points in the
electrical system...

I like that when fumbling behind and under the panel there is no screw
to drop or threads to strip.
I suppose screw terminals generally require an extra joint when
building. Crimping the ring terminal then the screw connection.

Considering the fact that reliability of the Fast-on Tabs seems to be equal
to the screw on terminals it comes down to accessibility.=C2- It seems t
hat most of the electrical connections are always in a hard to access locat
ion and getting a screwdriver into those locations is always a chore that g
ets considerably worse with age, I will go with the fast-on tabs every time

Subject: | Single vacuum drive alternator - good idea? |
I'm in the early stages of developing my electrical system for my newest project.
I'd like to build as light as possible for STOL. Initially considered SD-8
but loads and amp output at economy cruise too close for day/night VFR.
I've been moving toward the BC410-H (SD-20). From the little bit of searching
I've done, most installations are for all-electric planes as a backup alternator.
Are there any known issues of using the BC410-H in single (one only) alternator
mode?
It seems there are a lot of advantages not having brackets, belts, and mounting
hardware.
Thanks

Seems like intuition can be wrong, like in flying.
Thanks everyone.

John,
I'm using that setup as my backup alternator. Each flight, I test it as part of
my pre-take-off checklist. One time, it wouldn't come up at all - the plastic
shear-drive gear had failed. I would treat it like we used to treat our vacuum
pumps - rebuild frequently.
If you're primarily day-VFR - with an occasional night landing, you're probably
OK - as long as your cruise loads are not over 25 amps or so.....I think that
unit will put out about 28-30 amps with the primary regulator.
YMMV!
