Yes, the non-black lead is (+). The exact color
was changed to identify mod levels in the construction.
Don't know about the "left" terminal. The (+) lead
of the crowbar module goes to the (+) supply termnial
of the contactor . . . the black lead goes to the
terminal that is connected to the ground power control
breaker.

| Subject: | New from Harbor Freight |
I received a flyer from Harbor Freight yesterday, and one of the items
in it was a new "borescope" that was priced down from $139 (on their
website) to $99.99 in the local stores.
So, knowing that I would need one soon to exam the inside of my fuel
tanks when I get the holes for the fuel filler assembly cut (and who
knows what other little holes I'd have to inspect), I went down and
bought it.
I bought it...it was much better than I expected, and a lot more solid
than other Harbor Freight items I bought in the past. The first thing I
noticed was that it was very well packaged in a semi-rigid plastic
container. I'll use that to store it in.
I think it has a lot of neat features (in addition to the price), so I
thought I'd pass it on to you people in case you are looking for a tool
to examine those hard to view places as well.
The camera/light source head is 5/8 inch in diameter...the flexible
shaft is 3 feet long. The camera, flex shaft and mounting head on the
handle are attached with o-rings and are claimed to be water proof. The
whole thing (including the monitor) has a nice solid feel to it and
appears to be pretty rugged. Not the usual thin plastic like the Chinese
stuff often is.
The length of the camera head before it starts to be bendable may be a
problem for some applications though, as even though the camera and
it's fitting itself is only a little less than 3 inches in length, it
needs 4-1/2 inches of clearance straight in to get a full bend in the
flexible shaft. An application like this would be a good place to use
the 45 degree mirror attachment that comes with it that I mention below.
The monitor/display is in color, has adjustable brightness (in addition
to the LED light source brightness adjustments), contrast and
orientation (rotates the image in four steps) and can be removed easily
from the handle and remoted as it uses a wireless connection to the
camera. It also has a video output. It's cable has a standard RCA
connector on the end so you can input it to any device that will accept
a composite video input for recording or viewing on a larger screen.
The camera and LEDs runs on 4 AA batteries in the handle, and the
monitor has a rechargeable lithium ion battery. It comes with the
charger as well. It has three attachments that fit over the camera head
...a mirror, a magnet and a pick. So you can hunt down and move or pick
up things you find in those deep dark holes.
It uses super bright LEDs for the camera's light source, and the light
level is adjustable through a trigger on the handle. The camera does
pretty good in low light as well...I was viewing items in my house this
morning without using the LEDs.
You can see it online here:
www.harborfreight.com/cpi/ctaf/displayitem.taf?function=Search
And the manual is here:

Does anyone have any experience with the Tyco Rocker type
switch/breaker?
They are specified in the Digi-Key PTM as "secondary breakers", which
must
be backed up by a branch circuit breaker or fuse
http://dkc1.digikey.com/us/en/tod/TycoElectronicsPB/CircuitBreakers_NoAud
io/
CircuitBreakers_NoAudio.html.
This would seem to defeat the purpose of having the breaker in the first
place. What am I missing?

I mentioned the price difference in the last email.
It was $99.99 in the store...$139 on the website...note at the bottom of
the listing on the website, it says: "Prices on our website may or may
not be current prices in our stores"
I first saw it for the $99.99 price in a flyer that Harbor Freight sent
two days ago.

A gentleman at the local HF store explained that
their merchandising is handled through three
somewhat exclusive channels. The catalog sales,
website sales and storefront sales are different
pipes and may have differences in prices and
products offered.
On occasion, I've been to the local store with
a catalog in hand where the catalog price was
lower than the store price . . . they readily
offered the product at the lower price. But
sale prices in the stores are not tightly tied
to the catalog or website offerings.

A gentleman in another forum I belong to mentioned that Ridgid has the
same thing...so...
A search for "color inspection cameras" comes up with several different
brand names, and ALL of them are identical. Looks like this is one of
those cases where China makes it and sells it to everyone who wants to
market one, putting their own brand name on them. The prices for this
unit vary from as high as $450 for the 4UCAM model, to Harbor Freight's
$99. The average appears to be around $250. Dollars to donuts, Harbor
Freight is getting them from the same company that is making them for
Ridgid.
http://tinyurl.com/mw5yug
http://tinyurl.com/nskvv5
Also one of the accessories available for it is a 9.5 mm camera to
replace the 17mm one that comes with it (the camera and flexible cable
plug into the same hand unit). That size WILL fit in a spark plug hole!
It also says that the smaller camera has a shorter focal distance for
closer and smaller work.
http://tinyurl.com/makor3
I'll bet that it fits the HF model perfectly! Know I now why the unit
felt so substantial and "un-Harbor Freight-Like" when I opened up the
package! It was probably designed for Ridgid!
Now if we can only get HF to sell that smaller camera accessory...if
they ever do, it'll prolly be for $9.99 or so! <G>

Harley,
Could you cut/paste the coupon (if it was a coupon sale) or the flier? I
searched my HF emails and couldn't find the item, but if I had a
coupon/flier, the local store would honor it. Thanks, Don

Yep, they are great that way! I've done that myself in the past.
However, it wasn't a coupon sale...it was in the Fourth of July
flier...you may not have received it yet! I just got mine yesterday.
The price in the store scanned as $99.99, so it was in their computer as
that price...no coupon or flier needed. However...
I took the flier with me in case they didn't have the current price, and
ran into another gentleman who was trying to convince the cashier that
he saw the price of ANOTHER item for less but he didn't have the flier
with him. So, I gave him mine!
So, sorry, I don't have it (but neither did the store yet...the store
manager here said that they usually get the fliers that are mailed to
the customers a few days after the customers get them.)
If you don't get one by Monday next week, or your local store doesn't
have it by then, let me know and I'll see if I can dig one up locally.
HF is only about 5 minutes from me here.
BTW...in further research, I discovered that that inspection camera is a
Ridgid, and is last year's model that is being sold by the manufacturer
in China under a bunch of other brand names now that Ridgid's is a bit
different (use the same camera head and cable for both, though.)

Ken,
<< Does anyone have any experience with the Tyco Rocker type
switch/breaker?
I used the Tyco/Airpax/(now)Sensata/Snapak style rocker
circuit breaker/switches as primary power control in my
homebuilt in the mid-90s. Gave excellent service, not one
failure. I'm using the same style in the Sportsman I'm
currently building. The specific type is
R11-1-[amperage]-G06EV. They are Hydraulic-Magnetic type,
not thermal. You can find all the specifications at
airpax.sensata.com. Bob Nuckolls does not approve of this
arrangement. But this type is specified as usable in
life-critical medical devices which, together with my
personal experience, is good enough for me.

Not sure how long, it was in the Fourth of July flier, so I would guess
that it was good until at least the Fourth of July! But, in the past,
I've taken in old fliers with old prices on them (a few weeks old, not
years! <G>) and they have honored them.

Most 14v pitot heaters use 9-11A of continuous
running load (150W). Their inrush current is
high and protracted. I'd go with a 20A fuse/
breaker and 14AWG wire.

Yeah. They've been very consumer friendly here too.
Had a 2.5Kw generator still in a box that I wanted
to trade in for a 6Kw machine. I'd had it almost
three years. He looked in the computer and found
that it was still stocked in their system so he
took it back and gave me full credit toward the
larger machine.
On the few occasions I've had quality issues (like
un-sticky sticky-stuff on sanding disks, they
swapped out and/or refunded even if I didn't have
the receipt.
What they may lack in quality of some items, they
more than compensated for it in customer service.

There's a BIG difference between approval and recommendation.
I DON'T disapprove anything. I DO make recommendations based
on cost of ownership and using parts in a manner that
does put a mission at risk should a part fail.

These are indeed Cadillac breaker/switches . . . with
a price to match. But if your system design goals
include achievement of failure tolerant design
then the $extra$ cost only buys you a style
of device and adds nothing to system reliability
for the airplane.
I've not seen this class of breaker used
anywhere on a TC aircraft of any size or
price.

Beats me. This is the first time I've seen that
terminology used in describing the application
of circuit protection. Did some searching and found
this tid-bit . . .
Emacs!
This was excerpted from a book on wiring
design for large AC power distribution systems.
I don't think this applies to our 14/28V DC
systems in light aircraft.

According to the Dynon manual, "The maximum draw of the heated pitot controller/probe
is 10 amps." which is a bit less than the typical heated pitot.
They recommend at least a #14 wire for a 10'-16' run.
You can download the manual from their web site.

| Subject: | Re: noisy tach signal |
I have been unable to solve this problem so far and am considering a
different tach sensor or even buying / installing a stand-alone tach as I'm
getting frustrated in trying to get the IK-2000 engine monitor tach to work
with the factory recommended sensor. If anyone has any suggestions on what
I'm missing in making this work, any input is appreciated.
Here's where I'm at right now:
1. I cut the Hall effect sensor factory harness as short as I could for
installing connectors and used a 3-wire shielded cable from there to aft of
the firewall to connect the Hall effect sensor power, signal, and ground
wires. I soldered a short ground wire to the shield at the sensor end of
the cable and grounded it via ring terminal at the same mag location that I
grounded the p-lead shield. No improvement - in fact, probably worse than
without the shielded cable.
2. I moved the Hall effect sensor from the right mag to the left mag to see
if the same noise issue was observed and to see if the problem moved with
the sensor to the other mag. The problem DID move to the other mag and was
identical in performance (or lack thereof). So the Hall effect sensor gives
good rpm indication on the IK-2000 as long as the mag it is installed in is
NOT operating. As soon as I move the p-lead switch to "On" for the mag the
sensor is installed on, the tach signal becomes unusable. At low rpm (below
about 2000 rpm), the signal usually reads as if no signal is being recieved
(reads 20 or 30 rpm, same as when IK-2000 energized with engine off). At
high power settings, the tach indication bounces between reading correct to
being 100 to 300 rpm low and the number changes frequently even with
constant actual engine rpm. One interesting note is that the tach reading
is more accurate, i.e. less noise, when the engine is first started and run
from being cold (ambient temp). On initial (cold) startup, I start getting
good tach indication at about 1200 to 1500 rpm, allowing normal runup and
takeoff, and at cruise power settings everything looks good with the tach.
After shutdown and subsequent restart following initial flight of the day, I
don't get a good, or even close, reading until power goes above about 2000
rpm. After warmup in flight, tach indication is jumpy and reads low even at
2200 to 2300 rpm power settings. At any time, I can get a solid and
apparently accurate tach reading by securing the mag that has the Hall
effect sensor installed (I make the "apparently accurate" statement based on
past operating conditions: throttle position, sound, and airspeed/fuel flow
performance data, and the fact that the reading goes back to steady, solid
reading vice jumping around, and the idle readings are where they
should/have been).
3. As mentioned below, I tried installing 0.1 uF capacitor between
signal/gnd with no improvement. Same for installing 0.1 uF b/w +5V and gnd.
Whatever noise is being induced is driving the tach signal to point of no
pulses detected when the mag with sensor installed is operating. I can't
physically seperate the sensor line from the mag or the p-lead any more than
I already have.
Has anybody had success with the Westach Hall effect sensor installed in a
Slick mag? Anybody using this combination with an IK-Technologies engine
monitor? If so on either, did you encounter any noise issues that had to be
overcome?
Any advice/help is appreciated.
Thanks,
Chris

Noticed on a Icom 210A rear plug that they used different color wires of approx

wire as Aircraft spruce only has limited colors.Cheers
