From: Hariharan Gopalan Hello Group Intuitively screwed down ground terminals seem so much more reliable is there a reason the fast-on tabs are more popular? Thanks Hari ________________________________ Message 3 _____________________________________ Time: 08:58:42 AM PST US From: John B Subject: Re: AeroElectric-List: Fast-on tabs or screw terminals for ground? 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...

From: C&K 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 .

From: "John Bickham" 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 -------- Thanks too much, John Bickham Mark III-C w/ 912UL St. Francisville, LA I know many pilots and a few true aviators. There is a distinct difference that I have the greatest respect for.

Capen" Subject: Re: AeroElectric-List: Single vacuum drive alternator - good idea? 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!
