Maybe . . . I've had one or two switches returned over the years
that would not operate when oil pressure was applied but never any
that failed to show continuity with no pressure on it. Can you
cycle the switch with (shop air will do) and watch the terminals
with an ohmmeter?
B&C would be glad to replace the switch if it's being hard to
get along with.

Hi Bob and all,
The instructions for my UMA-Rotax tachometer call for a '1/4 amp inline
fuse' between the engine pickup and the instrument.
ATC fuses start at 1 amp. What would you suggest to satisfy this requirement
? Do I have to resort to those glass cartridges ?
Thanks,
Gilles

I had the same problem with my egt/cht unit so I just put a 1 amp fuse at
the main bus to protect the wire and left the 1/4 amp glass fuse holder
inline. Ugly but don't know how better to do it.

| Subject: | Military-style Ground Power Plug |
--> AeroElectric-List message posted by: "William Bernard" <billbernard@worldnet.att.net>
I'm installing the military style, three pin ground power plug. I'm using Fighre
4 from Bob's article on ground power plugs as a guide. My question centers around
the contactor. I have one with three terminals, two large ones and a single
small one. It appears externally similar to the S701-1 contactor otherwise.
1) Do I install a diode from the small terminal to the large terminal on the contactor
that will connect to the large center pin of the plug?
2) Will the red wire of the OVM-14 module go to this same terminal?
3) I assume that the black wire of the OVM_14 will go to the small terminal. Correct?
4) The large terminal marked "BAT" will connect to the battery contactor and the
unmarked large terminal will connect to the center pin of the plug. Right??
Thanks for the help.
Bill

That's about all you can do . . . whoever built that
requirement into their design should be tied up with
their soldering iron cord and whopped about the
head and shoulders with their slide rule. There is
NO excuse to make a customer comply with this kind
of silliness . . .

No, a 3-terminal contactor cannot take advantage
of the small, sequenced energizing/de-energizing
pin in the connector. You need a 4-terminal
device so that you have access to both ends of
the contactor coil.
This is why we stock the 4-terminal device. It can
substitute for a 3-terminal contactor as supplied
with jumper . . . but will serve in the unique situations
requiring 4-terminals by removing the jumper.

I am looking for the brightest LED annunciator lights that would be viewable
in direct sun light. If these devices are not available for direct
sunlight, I would like the next best option. A 45 degree viewing angle
would be preferred but could accommodate smaller angle as necessary.
Hopefully several colors would be available. Source would be 14 Volt and
dimmable as dictated by ambient light.
Any help would be appreciated
Jerry

I don=B9t know squat about LEDs but can vouch that the one supplied by lectric
bob in his LVWM is one very bright light, which will get your attention in
the brightest sunlight. I think its flashing helps ?

No, he got a rejection notice from my cox account. He resent

See http://www.flamecorp.com/pdf_files/aml_1.pdf
page 44 shows some LED custom annunciators.
