| Subject: | Re: Today's trivia dump . . . |
Just to close the loop on this thread...
We exchanged a few posts a couple of weeks ago about the feasibility of making
a DIY spot welder for attaching battery tabs. I've been fiddling with the idea
since then and have come to the conclusion that there's little point in trying
to beat the Chinese at their own game.
With the components, an enclosure, some heavy gauge wire and something rigid and
durable (tungsten TIG rod?) as welding tips, my bill of materials ended up nearly
as costly as the imported spot welder that Bob found on eBay. The only
way it would make sense to build is if our time is worthless, or as a hobby project.
Maybe I'll pursue the latter when most of my workbench isn't in storage.
For now, I'm setting it aside.
Eric

Thanks for mulling the question over Eric.
I concur. Youtube has several project videos
on salvaging power transformers out of microwaves
and rewinding a 100A secondary good for a few
volts. But current control and timing was another
matter.
I may ask for a battery welder for Father's Day
or something . . . not that I need another project
right now!
Dr. Dee and I are working with the local volunteer
ambulance service. She got her EMT ticket a few weeks
ago, I should finish my tests next weekend. I'm just
driving right now. We were invited to join the
Gyp Hills Prescribed Burn Association. We're
going to have our own fire truck!
We had two humongous wild fires over the past
two years . . . largest in Kansas history.
Could have been contained at a fraction of
the damage with more diligence to prescribed
burns combined with knowledgeable/willing folks
to operate equipment.
It's interesting to watch the expressions on
the faces of city slickers when we tell them
that some days we go out to fight fires . . .
other days we go out to set fires!

| Subject: | Z-17 and over voltage warning lamp |
I've wired my airplane based on the Z-17 diagram, which uses no master
contactor, a PM alternator and crowbar OV adapted for that alternator.
Notably, Z-17 omits the panel mounted OV warning lamp which is activated
by the OV relay being tripped- the lamp is wired to the normally closed
contact on the relay, as shown on the diagram which came with the
alternator.
Today I applied power to the panel for the first time, and while no
spoke escaped, I now know why Z-17 omits this lamp- without a master
contactor, this lamp is illuminated constantly when the master switch is
off and only goes off when power is applied to the alternator control
relay. I would like to use this lamp on the panel, but the only fix I
can noodle out is to run the lamp wire through a switch, probably using
a 3-pole for the master switch (which now controls both battery and
alternator on one switch.)
Has anyone else tackled this with a different solution?

Z-17 has a recommended solution. Active notification
of low voltage in the form of sensor and light.
Eric Jones has a LV Warn product http://tinyurl.com/yj7g5jh
I'll have a replacement for the discontinued AEC9005
product later this year.
You can built your own from details on my website.

No doubt there are other options out there.

Perhaps a LED (with series resistor) in parallel with the 5 amp circuit breaker.
