> Dan, If your metric contactor studs are 6mm X 1.0, the 21042-4 will go right
on.
Thanks, Rick!
I do have some metric studs, come to think of it. Think it's the battery contactor,
not sure about the starter. Battery itself, too, I think.
Another thought is how much torque to put on these. I suppose I otta look that
info up from the contatctor specs. If the studs are embedded in plastic, seems
the 50-70 in-lbs could damage it.
And sorry about the late response. Since your post wasn't a reply to mine, I didn't
get an email.

These are generally hard copper or brass studs.
I don't think you're going to find anyone offering
recommended torque values. Us internal tooth lockwashwers
under the nuts and snug 'em up.

I don't know about other manufacturers but these : http://www.trombetta.com
/dc-contactor-products.cfm?id=51 have the torque values on the label. You
can open the drawing and zoom in on the label.

I just bought this power supply for my hangar:
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=250852141183&ssP
ageName=ADME:L:OU:US:1123
I will plug it into my airplane's electrical system whenever I'm in the
hangar and running the instrument panel, such as when updating the
navigation database or running the "glass cockpit" in simulator mode for
practice. I'll also use it occasionally to top off the battery. I'll
plug it into a 120VAC wall outlet and it will supply 12VDC (adjustable
from 10.8 to 13.2 VDC).
If you zoom in on the photo at the left on the above link, or scroll
down on that page, you'll see that it has seven screw terminals for wire
connections, labeled as follows:
"L" Is this the AC line in?
"N" The other AC line in?
The ground symbol; the ground if I use a three wire AC cord?
"-V" Probably DC volts out, minus?
"-V" A duplicate of the previous one?
"+V" Probably DC volts out, positive?
"+V" A duplicate of the previous one?
It came with absolutely no documentation or instructions and I'm not
100% certain how to hook it up. I emailed the vendor, who is in China,
who has not responded.
I measured a few mega ohms between the L and N terminals. There are a
few tenths of an ohm between the two -V terminals. Same between each of
the two +V terminals.
Are my guesses above reasonable? I only have $15 into this, including
shipping, so it won't be the end of the world if I destroy it hooking it
up wrong, but I'd just as soon not.

Hi Dennis,
Nice looking, practical power supply. While we wait on our seasoned
electrical gurus to check in, here's what I'll bet
you'll see.
The L-N-G screws expect you to use a three wire cord, NOT a two wire.
Line, neutral, ground. Easy enough.
First, I'd get that cord hooked up and plug it in to 110V AC. Then,
take your multimeter, I'll bet you have two sources of
pos & neg 12V DC sets of screws. Find out which ones does what.
Attach your "positive" multimeter lead to one "+ screw", then see if
BOTH negative screws give you 12V, which would
tell you they have a common ground. (it probably does)
Your answer as to how it functions will be whether or not those two "+"
terminals are distinctly separate
12V DC power leads.

I have the exact same thing and will wire it up the way you have described.
Except remember that the "N" stands for Neutral and is usually grounded at
the breaker box and usually the white wire. The black would go from the
breaker to the "L(ine)" connection. Ground is usually Green. So while "N"
is "the other AC Line in" they are not the same and you will get fireworks
if you hook them up backwards.
You may already know this so pardon the explanation if not necessary.

FWIW
I recall hearing that some types of power supplies are unhappy unless
there is some load on them. Don't remember what type. May not apply
here at all or may not even be true. Don't want that smoke to get out. :)

Thanks for the speedy and helpful answers! I'll hook it up within a few days and
report back.
