| Subject: | Generator Regulators |
Does anyone know of another company, besides Zeftronics, that manufactures
or supplies generator regulators? Whilst Zeftronics seems to have the lead
in supplying many different regulators their service is really bad, taking
more than three days to respond to emails, and then not responding properly.
Its taken me almost two weeks now just to get the correct information from
them and I fear that it will take the same amount of time to place an order,
by which time delivery will take as long because of the time of year..

Bob N,
I believe he is a spammer. The subject line of "Kenworth Exhaust" and his link
to view automotive exhausts
have zero to do with airplane electrics. At least, this is how I interpret his
post.

Well, their generator regulator is top notch. You do not need to
purchase from Zeftronics directly. In fact you will get a better price
from Chief Aircraft or Sacramento Skyranch. The regulator came with full
documentation, items that needed checking prior to installation so that
you don't "smoke" the regulator with a defect in electrical system. I've
had mine installed for over 10 years and 700 hours flight time with no
issues. I believe B&C Electrics also offers a good solid state
regulator. I would never go back to a mechanical regulator.

Yeah, but it seemed prudent to give him the benefit of
the doubt. He's not presently subscribed to any Matronics
forums.

The regulators offered by B&C are not suited to
service with generators. Alternators are inherently
current limited and do not require reverse current
cutouts. Generators are nothing more than parallel
wound motors that deliver energy into the system
if you spin them fast enough that 'counter-emf' exceeds
system voltage. Their regulation dynamics is different
too.
Modern micro-electronics would make it much easier
to build a generator controller . . . it would simply
be a scaled down version of those devices found on
Beechjets and Hawkers.
But the market is pretty limited. Right now, Zeftronics
is the only game in town that I'm aware of.

I too can vouch for the quality of Zeftronics products. When I was the maintenance
manager for a four Cessna flying club I switched all of them to Zeftronics
units. And, yes, a number of the aircraft parts houses stock their products.
Also I would not hesitate calling Femi Ibitayo, the owner of the company at 800-362-8985.
Back in the day I met him at Oshkosh and spoke to him several times
after that but not recently.

| Subject: | starter switch wiring |
I wired my starter switch and magnetos like Z-26 with the magneto
wire shields both connected to the ground terminal on the switch and the
other end of the shields connected to motor ground. Before installing the
switch I confirmed continuity was correct in all switch positions. Why
would one have continuity to ground from the magneto post even when the
switch is in the "both" position. In fact there is strangely continuity
from magneto post to magneto post. If it matters, the magnetos are Bendix
and both have impulse couplings (no jumper required on the switch). I
assumed that the magneto post is isolated from ground unless its wired to
ground. Is that incorrect?

No it is quite correct. What your ohmmeter perceives
as "grounded" is really a measurement of the VERY LOW
resistance of a magneto's primary coil (less than 1
ohm as I recall).
The difference in measured resistance for a magneto's
p-terminal to ground with points open verus points closed
is very hard to detect with a garden variety ohmmeter.
This is why one needs a "buzz box" to time a magneto.
The "buzz box" is responsive to changes in AC impedance
as opposed to DC resistance of the magneto p-lead circuit.
Here's a compendium of documents that speak to magneto
timing tools
http://www.aeroelectric.com/articles/Magneto_Timing/
and even a couple of DIY buzz-boxes . . . one by
the inestimable Jim Wier.

| Subject: | Re: ectric-List: |
Thanks Bob. That makes sense and educated me as to why we use timing
devices instead of simple conductivity tests. I had confirmed that the
issue I was seeing was indeed at the magneto but I was lost once I saw a
perceived ground at the post.

Jay,
Is it a generator or an alternator regulator you need...? I don't know
about the older generators but, if you have an alternator, it is a Ford
product. Last time I needed one, I went to a Ford truck or marine
business and bought the Ford heavy duty regulator. It was less than $30
US. Same or better than the so called approved units.... Could be the
same for the older generators too...

Thanks anyway David and all who answered. I have had replies from
Zeftronics, but they take 2-3 days to reply and then it goes to 3-4 days
because of the time difference between here and the US so its most
frustrating.
But I do have an answer now although it has now taken 2 weeks to get to this
point!
