Listers
I have obtained an almost new Nipon Denzo alternator off a Toyota which I intend
fitting to a Lyco320 In my RV9.
I have a couple of questions. Firstly I assume it's internally regulated although
it has a 3 wire socket, what are the 3 connections for and is a mating plug
readily available. Van's sell one that looks as if fits.
Secondly it is currently fitted with a flat belt pulley which I need to change
this to a V belt. I seem to recall Bob Avery used to sell a larger dia pulley,
is this worth considering and if not could anyone direct me to source of standard
sized pulleys.
Thanks for your help.

Jeff,
According to the KK-145 Installation Manual the "Mic Key-Comm" is connected
to pin 7 of the P401 connector. Viewed from the rear, P401 is the top
connector and the pins are numbered from the right starting with pin 1.
Just as a double check, your receive coax should be connected to pins 9-11
of P401. I tried to scan the schematic to send to you but the manual is so
old that it took maximum resolution to get a readable copy. With that, the
file was 14Mb which is too big for e-mail.
Regards,
Bob Lee

Hi all,
Does any one have a wiring diagram for a King KX 145? If so, can you tell
me which wire(s) is for the push to talk activation?
Thanks in advance,
Jeff

| Subject: | Voltage Stability Problems |
Bob,
--> AeroElectric-List message posted by: Ken Harrill <KHarrill@osa.state.sc.us>
I am using a generic Ford regulator and I am having problems with voltage
instability. If I connect the field terminal on the regulator (A and S)
directly to the buss terminal of the master contactor, the voltage becomes
stable. I tried connecting the field terminal to several points in the
circuit between the master contactor and the regulator. It seems that the
further downstream from the master contactor that I make the connection the
higher the resulting system voltage. The instability seems to be associated
with the circuit breaker ( I am using OV circuitry per the Aeroelectric
Connection). I have installed a new voltage regulator and tried two
different circuit breakers without improvement. My questions are:
1. Is the "S" terminal of the regulator the "sense" input? If so could I
connect this terminal permanently, thru a fuselink, to the buss terminal of
the master contactor?
2. Why would the circuit breaker cause instability? The two that I tried
are Klixon 5 AMP breakers. Both show .6 OHM resistance. I plan to buy
another breaker in case I have two bad ones.
3. What is a acceptable system voltage? When the field wire is connected
directly to the buss terminal of the master contactor, the system voltage is
14.4 and stable. When connected to the buss side of the breaker, the system
voltage is 14.7. When connected to the regulator side of the breaker, the
system voltage is 14.9 to 15.3 and is unstable.
Any help will be appreciated, as always.

I sent out the message below. I just wanted to acknowledge Fault Tree's
Joe Belland
Technical Support, Isograph Direct
(949) 798-5607
who patiently pointed out the Windows path to uninstalling his program (to
someone who should have known).
That's diligent salesmanship.

With my hairtigger reaction, I neatly downloaded "Fault Tree" at the behest
of some worthy on net - thinking I would be miles ahead while I had the
time.
Unfortunately, it came to pass that it was not the fault system
which the group would find useful. It now sits like Oomph in my hard disc
and I find no easy way to "uninstall" it.
Is there some knowledgeable guardian who might advise me how to dump
the megas for all time?

Aeroflash heads
--> AeroElectric-List message posted by: Neil Clayton <harvey4@earthlink.net>
Mark....thanks for your interesting post. I saved your mail with the intent
of researching the references you cite at the RV archives. But I can't find
anything. I expect it's not the RV-8 list that I know about, but some
other. I need this info since I'm doing my strobe research now. Could you
point me where I can read everything you refer to?
Thanks
Neil
