REFLECTOR: Alternator

[Chuck Jensen]

K/K/T, thanks for all the ideas. I was leaning toward BNC but wanted to
double-check.  The new Skytec seems to be a good new product and the BNC
seems to be a good old product, so you make your picks and take your
chances.  Kent, I thought my BNC alternator had crapped on me a couple
months ago.  I took it off to check it but of course, the Parts-Be-Me
auto shops all have the automated test systems that if you don't have a
code for the alternator, the high dollar equipment is worthless, though
its still more valuable than the $6.50/hr help that wandered in off the
street.

I checked with BNC and they said to an old-time alternator shop and they
would know how to test it, but BNC doubted that it was the alternator,
not based on the symptoms but just the low failure rate.  Sure enough,
it was the Avionics shop that had done the IFR recertification must have
pushed/pulled/yanked something.  They said they absolutely couldn't have
screwed anything up, but I asked them to look things over anyhow.
Magic: they again claimed they found nothing but suddenly, the
alternator was back on line, the trim system worked and the CB for one
of the alarms quit popping.  Amazing how doing nothing causes problems,
then doing nothing again fixes 'em.

By the way, the BNC alternator was only a few year old, but still smooth
as glass.

If anyone is considering a new alternator I'm happy with my new B&C 70
amp on my IO-540K1J5. 

The previous Prestolite had been wired incorrectly about 15 hours
earlier but I didn't know it since it had not failed all at once (which
would have kicked my trouble-shooting mindset down the right path). Just
exchanging the Prestolite's core would have been much cheaper but I
sprung for this all new, recently-hyped B&C since I have no back-up
alternator or battery system. 

My friendly A&P and I had an issue about connecting one of the wires
(because we were trying to hook it up like the old Prestolite) and B&C's
tech support happily set us straight.

Anybody need a 70 amp paperweight? It has Prestolite orange with
scorched antiquing to match any hangar-office decorating needs.

BTW - I'm happy with my Skytec 149-12PM starter (it doesn't have the
easily replaced internal shear pin but it cost lots less than the HTI NL
for now).

	What's the current concensus on starters?  BNC or SkyTec HTI (hy
torque in-line, or some such)?  I'm not interested in the PM Skytec but
was trying to choose between the non-PM (permanent magnet) starters?
