I posted this on VAF but not much yet.
http://www.vansairforce.com/community/showthread.php?t=124714
Basiclly, I am impressed that someone carried a spare alternator with
him on a trip. Talk about being prepared. However, it does seem like a
good idea to know if such an option exists for the -10. Does anyone know
if there is an equivalent auto parts alternator that will work for us?
Thus, we can either carry around a cheap spare or know what to look for
at a local auto parts store, even better. This would be a backup to the
stock Plane Power alternator. Does anyone know of the closest direct
replacement? From the limited searching i have done online, the mounting
bosses dont seem to be the same.

This is the one I used before replacing with a plane power. It works well
for 10 years:
Mitsubishi 60 -70 amp, internal regulator, internal fan. Various makes are
suitable. Model used listed under 1990 Mazda 626, 2.2L, L4, Fuel injected.
Available at
Advance Auto parts for $95, as well as most auto stores. It comes with a
spline pulley so you will need the auto parts store to replace it with the
pulley off of your old alternator.

Would that be a direct bolt on replacement if the Plane Power quit while away from home?

It fits the Van’s alternator boss mount – which I believe is the same (or close) to the Plane Power mount. The connection plug for sensing voltage and alt light (if used) may be different but that is not a big issue for a field repair.
If you ever need to do this take the failed Plane Power unit to the auto store to make sure – you’ll need it to swap pulleys anyway. Many stock car alternators have this same form factor. On the RV-8A I first went to a alternator shop and had a “special” one made (this was before Plane Power). It lasted 50 hours. I replaced it with this off the shelf part and it lasted 10 years. It failed gradually with the voltage regulator sometimes needing a load applied before it started working correctly. The replacement Plane Power has been flawless on the RV-8A and well as the RV-10.
BTW – I found the alt light connection to be useful as a “you left the ignition on” alert. I use a DPDT switch for each ignition, ignition on one side and a 12vdc buzzer from Radio Shack on the other (buzzer(s) mounted on the engine side of the firewall but still heard in the plane with headphones on ). The buzzer(s) ground provided by the alternator light connection. Thus if the engine is not running but the ignition switch is on, the buzzer sounds. Once the engine is running the alternator ground goes to buss voltage so there is no voltage across the buzzer and it is silent.

I managed only 79 hours on my auto alternator when it gave out on a cross country flight. It was an internal regulated Nippondenso for a 1978 Suzuki Samurai. It was a factory new unit, not a rebuild. I had a blast tube on the back to keep the regulator and diodes cool. The alternator indicated an internal ground fault when they tested it at Advance Auto. I bit the bullet and replaced it with a B&C alternator with external voltage regulator.
