| Subject: | B&C Alternator Conversion and Russian Horizon |
We're about to go for a B&C conversion into our Yak-52. Our mechanic, who has done
several conversions (all EFIS!) is concerned that the B&C 35amp alternator
may not be able to cope with the draw from the Russian horizon. We have one fitted
in the front only.
Any experience of this please?

I run that Alternator in a CJ with both front and back AH's fully operational ....
never had an issue.

The original mechanical voltage regulator and horizon draw 3.6A (on startup a bit
more)
You can save 1 amp by using an electronic voltage supply for the horizon. The turn/bank
also runs on that 3 phase voltage from the regulator.
The electronic one also weighs less.

The AI's and T&B are powered by mechanical Inverters (motor generators)
which convert 28 vdc to AC 400hz (can't remember the voltage).

| Subject: | B&C Alternator Conversion and Russian |
Horizon
The B&C SK-35 can easily handle the Motor/Generator or Inverter Power Supply (whatever
name you choose to call it) used for the both of the AI's in the 52.
With one warning. You must have your batteries in good condition. The SK-35
is rated at, amazingly enough, 35 amps. That said, I would not recommend
pulling 35 amps out of it continuously. Personally on my installs, I have recommended
a 30 amp circuit breaker versus 35, which still leaves you with over
800 watts of power. What I have learned is that the SK-35 is not tolerant of
instantaneous current draws that exceed 35 amps directly to the alternator.
This kind of situation would normally never happen UNLESS you have bad batteries
(assuming two 12 volt batteries in series). Since we do not use batteries
for starting, it is easy to miss the fact that the batteries are getting weak.
Good enough to open an air valve and power shower of sparks to start the
engine maybe... but then with the engine at idle, the batteries trying to charge,
Inverters powered up, along with everything else, then yes... it is possible
to take out the alternator under those conditions. This happened to a B&C
equipped CJ at an airshow one year when a spectator happened to flip on the Master,
it went unnoticed, and the batteries went dead. The owner jump started
the airplane, so far so good. When the jumper cables were removed, the SK-35
had to assume all the load and all at once. POOF. $700+ alternator now inoperative.
Another fact worth repeating once every few years or so is the fact
that regardless of what charging system you are using, the AGM, or Gel Cell batteries
typically used have a maximum charging voltage *AND* current. Both can
easily be exceeded in our day to day operation, causing the battery to vent,
lowering the capacity and leading to an eventual demise. If you run your batteries
until they actually fail, again this is asking for bad things to happen.
So once in a while, before starting the engine, turn on the master, look
at your ba!
ttery vo
ltage, and then turn on a big load, like Pitot Heat for example. If the battery
voltage drops down below 20 volts or so, it's time to replace the batteries.
Yes, the short answer was simply that the SK-35 will be fine, as long as you have
good batteries, but I repeat the long version every so often as I see folks
installing TINY batteries to save weight, or whatever other reason, and then
never realize there is another side to that coin. I.E. The smaller the batteries,
the lower the maximum charging current, thus the above becomes more likely
to happen.
