Chris,

I see you found my neighborhood cyber bar. Have a beer and keep an eye out
for flying pool cues and bottles.

The good news is that no one has jumped up to say that the problem must have
started somewhere else and a new regulator will just self distruct in the
same way. Could still happen but, if it was common, that's what we probably
would have heard.

The other good news is confirmation (recognizing that you have to take all
NG stuff with a grain of salt) that the generatior part of the dynastart was
not being used and the alternator is an addition. That means a separate
regulator and solonoid, readily available and not terribly expensive, are an
option.

What people are calling a starter solonoid isn't really. A solonoid pushes
the drive gear into place on some starters then disengages them so they
won't be turning and generating power when the engine is running. (Standard
starters must do this because there is no way to cut off power to the field
windings). When I was flying, an important step after starting was to turn
on power to the panel in special steps watching the ammeter to be sure the
starter (Bendix mechanical engagement / disengagement in this case) had not
remained engaged generating power that would fry the entire avionics stack
when the engine was brought up to speed.


Ah Roger, you must be one of the younger generation who dosen't
remember "Bendex" starters where rotation of the starter drove a
pinion gear out a spiral shaft to engage the ring gear on the
flywheel. The solenoid was a proper solenoid (remote switch). After
the engine started and the starter button was released a coil spring
retracted the pinion gear. :-)

I sure do. I had just that arrangement on the airplane I took care of and
flew until a couple years ago. Remember, when you fly GA aircraft, you are
trapped in a WWII era technology time warp due to the stifling of innovation
and improvement by FAA paperwork.

I had to go out and lube that Bendix twice a month with silicone spray to be
sure it would disengage because it was right up in front where any rain
drove straight in as the plane flew.

Back in the good old days (automobile days that is) you took a squirt
can of kerosine and squirted the bendix occasionally. Of course, when
one of ours stuck and wouldn't disengaged and started to sound like a
siren we could get out and run....

What is the story on these home built or kit planes? I thought that
they could get, at least little way, away from the FAA.and all of its
guidelines and regulations.

Back when I was in grade school my father belonged to a club that flew
off a grass field. J-3 first and later upgraded to a taylorcraft that
had real adjustable trim tabs. I remember that there were regulations
but I didn't remember all the hoopala that I read about in the flying
magazines today.

Thanks folks for all the input and great suggestions!

I have located a 2nd hand original regulator from a gentleman in the
UK (ain't the net grand!??!). I will, more than likely, take both the
alternator and the starting generator out to have them inspected prior
to installing the new regulator. I truly think that after 35 years,
the regulator had just had enough and it was time to pass on to
greener pastures, but I know not to trust that theory entirely...this
is a boat after all!!! grin

It also looks like I have a few days of pencil and notebook ahead of
me tracing the lines back to create a more "up-to-date" schematic that
even I can understand and see if I can figure out how all this wiring
was done. Eventually I will seek out a re-power, but finances are not
going to allow for that (at least for a few years), so if I can patch
her up enough to get a few more seasons out of her, I will be happy.

Oh...I will also pop the cover off this new unit and check the
contacts there as well. I have been assured that it is in good working
condition, but since I will be cleaning all the other points of
contact prior to reinstalling everything, I may as well check that
too...

This wasn't a kit plane. It was a 1976 Cessna 172 N, probably the best
behaved aircraft ever designed.

I did a little work on cessna's in Vietnam the two place (I think 170)
model and the later pusher-puller thing with the retractable landing
gear. By the way, they ferried those push-pull airplanes from the
states to Vietnam.

Was your's a tail dragger?

No, tri gear.

My assessment, as well. There was a reason Cessnas held something like
90% of the trainer market when I did my training.
