Arcane question, and sort of long, but here goes....

Last night, young son was in the process of adding foglights to his
car and asked me for some wire to extend the harness. I wasn't sure
what the current draw would be so I grabbed one of the foglight
assemblies and connected it to the Eico 1050 battery charger/DC power
supply which has been part of my garage tool clutter for nearly 50 years:

http://home.comcast.net/~jwisnia18/temp/eico1050.jpg

When I cranked the voltage up to 13, the bulb lit brightly and the
ammeter on the Eico read around 9 amps. That seemed sort of high to me
so I asked the kid, "How big a fuse is in the harness which came with
those lights?" he looked at it and told me it was a 15 amp fuse. 15
amps for TWO 9 amp bulbs? Obviously something was't right, so I got my
Simpson 260 and saw that the current drawn by that bulb was really a
bit less than 5 amps.

Since SWMBO was out getting some "retail therapy" I had some free
time, and taking the Eico into my workshop, I opened it up,
disconnected the leads to the ammeter and fed it with my bench supply.
That verified again that it was reading almost twice the DC current
passing through it.

By a couple of "cut and trys" I found that about 4 inches of 18 gage
solid copper wire shunting the meter made it read correctly enough for
"gummint work", so I soldered that wire in and closed the Eico back up.

I believe the ammmeter is what I used to know as a "moving iron" type,
and IIRC the restoring force was supplied by some kind of permanant
magnet field, not by a mechanical spring. Am I right about that?

I doubt that Eico installed a defective meter when they built the unit
around 1965 (The date marked on the meter.) and I'm guessing that the
meter's restoring magnet weakened over 50 years, increasing its
sensitivity to nearly double.

Anyone have any similar experience with those kind of meters, I'd
enjoy learning more, just for the shits and grins of it.

Thanks guys,

Jeff

Isn't there normally a shunt across the meter movement? If so, is
it accurate? If it had changed in value that could account for the
increased reading.

There was none across the outside, and the meter was crimped shut, so I
didn't bother looking inside.

But IIRC that kind of meter just used a few turns of heavy wire
connected across it's terminals to create a magnetic field which altered
the total dc magnetic field inside and made a piece of iron on the
pointer shaft change its position.

Jeff

Those moving iron ones didnt usually use shunts, as you say. They were
cheap, nonlinear, undamped and inaccurate, and I expect the meter's
always been that way. It was probably a bit of marketing spin.

The SLA batteries have F1 terminals. I'm assuming I simply need a short
cable with F1 connectors at each end. I'm not really comfortable
fabricating my own for this kind of application (involving batteries).

Any auto electrical shop can do this for you in one minute or you can buy
the parts and crimp tool at an auto supply shop.

Someone with more knowledge than I tells me that the jumper for this
UPS did not have a fuse, it was just a simple cable.

Makes it simple and sounds reasonable. This is an easy job BTW.

Nope. Still a spring.

decide what to follow through on and lawyers prosecute or defend based
on those discoveries. Even then, one is not guilty of anything until

I know it's a long-shot, but I picked up an LED sign (labelle
industries)at a garage sale that is programmed with an IR keyboard,
which is missing. Is it possible to somehow figure out a way to
program this thing? The IR decoder is a philips TDA3048. It does
work, as it is in "demo" mode when powered on.

ISTR there is a project to document every IR remote in the world, on Linux
boxes IIRC. Source Forge perhaps?

I hear what you say about a spring, and it makes sense that there may be

one there. But it's interesting that the reference link you gave
mentioned "springs" when describing the first two meter types, but not
the moving iron one. Wonder why? Probably just an oversight.

Does the sign also have a serial port (db9 or db25 connector)? Many
of them do.
If so, it's programmable from a PC.
I have source code for some limited control of an Alpha sign that's
probably similar.

Perhaps they felt it was redundant. It's like holding two magnets N to N and
S to S - you are the spring holding them together.

You can test for a spring without dissection. First, does the meter jump to
a position and oscillate a bit before settling? If so, put your ear (or a
stethoscope) to the meter panel and tap it sharply. If there's a spring in
there it should ring like a bell. If you see that resonace in the meter
movement, yet hear no spring, then you and Homer are probably right, the
spring would be entirely magnetic.

 

[Lostgallifreyan]

The pointer itself might ring with the test I described, but dull sound,
not the sustained ring you'd likely hear from a spring designed to maintain
a pointer position.

Hi!

Problem: I lost the original jumper cable.

What does the manufacturer of the UPS have to say? They might send you one,
if they are still in business.

Or maybe this is so trivial that people
fabricate their own.

The fabrication part will be easy and requires easily obtained tools, wire
and connectors. If you don't want to make one, or feel uncomfortable doing
so, a number of people might be able to help you--electricians, car audio
installation companies, well stocked and knowledgeable electrical supply
houses...even a dead UPS might yield a usable cable if you can find one of
those.

The SLA batteries have F1 terminals. I'm assuming I simply need a short
cable with F1 connectors at each end. I'm not really comfortable
fabricating my own for this kind of application (involving batteries).

Use a wire that is similar in size to the the others that feed the
batteries. The same goes for the connectors. There's no fuse in this wire or
anything special like that. (If you were to look, you'd find the fuse(s) on
the main board in the UPS.) The only thing you'd have to be careful of while
you're working is an accidental short of the battery terminals. That's very
unlikely to happen.

Could it be that the meter was calibrated to compensate for the fact
that when it's hooked to a battery, it only supplies current when the
charger exceeds the battery's voltage, while on a lamp it would draw
current from zero on up?
