Subject: | Re: Should battery be charged with a higher voltage? |
Bob, Thanks for your words of wisdom.
To Ron P,
I could not find any reference to a diode on EuropaOwners.org. But I assume that
the diode is inserted in the regulator sense wire. I had thought about doing
that, but voltage measurements indicate that my battery is kept fully charged
with the 13.6 volt regulator set-point.
The charging instructions in the Oddyssey manual
http://www.odysseybatteries.com/files/US-ODY-TM-001_0411_000.pdf
pertain to a discharged battery. Since my PC680 battery never gets discharged,
the Continuous Float Charge voltage of 13.6 is adequate.
I appreciate your input.
Joe

Even if it were to be somewhat discharged it would still fully charge at th
e 13.6 volt setting=2C it would just take longer to do so assuming the alte
rnator has some headroom above the "normal" electrical loads of the aircraf
t.

Will my B&C LR3C-14 regulator properly control the Continental's alternator? I
can easily set this up for a ground-run test....
Are there different regulators based on current output capability?
Thanks again!

Yes
>Are there different regulators based on current output capability?
Generally no. The smallest of 35A alternators draws
about 3A max . . . so does a 100A machine. There's
an advantage for keeping field currents low (control
of internally dissipated heat). Larger machines just
get more magnetic flux by more turns of larger wire
and keeping the field current manageable.
Further, unlike generators, the closed loop dynamics
of alternators fall into a much smaller universe of
characteristics such that regulators can be quite
generic. The B&C linear regulator was optimized for
the B&C alternators and may not be as nimble footed
for transient response on a 'foreign' alternator but
not bad enough to raise risk for the success of the
experiment.

Subject: | snorkel for alternator cooling |
Hello all,
This is only marginally electric, but I need information. My RV6 has no
alternator cooling other than the (reverse rotation) internal cooling fan.
I'd like to install a snorkel to capture some cooling air at the air inlet
ramp and lead it (tru a hose) to the rear of the alternator. Does anyone
know of a source for these little alum. snorkels? I have no means to weld,
braze or solder alum. I guess that I could make one out of an old tin can,
but that's kind of tacky.

Are you sure you need one? I'm aware of
no alternator installations in an RV that
experienced difficulties attributable to
overheating.
Is there something different about the
way your alternator is installed where
it has been confirmed that extra-ordinary
cooling is needed?
Way back when, we used to do max hot day
climbs at best angle with an alternator
at full load . . . and then justify the
state of the machine's cooling. Truth is
that an alternator never gets operated that
way. So what ever cooling was added to meet
that capricious demand was wasted effort.

Just wonder, Ralph you've told, that your B&C is from a RV-6? That would
probably be a 14V system where the Mooney has a 28V System, just
carefully check.

If it's switch mode then you are stuck with the 110-140 vac unless you buy a

Schumacher specifications state input voltage 110-140v ac. Thanks for any

I wouldn't recommend it. It is nylon material IIRC. OK but not great
for warm temps under cowling.
Scat tube would be the aviation product of choice.
