I have a 24 volt military truck that I use for snow plowing. In the
past I've had trouble finding 6000 series 24 volt sealed beam lamps
for the plow frame.. And when I did I have found them to be very
expensive. So I came up with a circuit using a DPDT switch in which
both the high and low circuit lamp filaments are wired in series when
power is applied. I was very careful to initially select two lamps
that drew exactly the same current when tested on my bench power
supply. The arrangement has worked flawlessly for the past few years.
The other night I had occaision to look at the lights from outside the
truck while it was running. Charging voltage on a 24 volt system can
run as high as 28 volts on a typical 24 volt system. Although I didn't
try to measure the voltage accross each lamp, I noticed that one lamp
is slightly brighter than the other on the low circuit. I'm assuming
that filament is getting weaker and thinner and will likely fail
shortly. And of course when that happens I'll lose the low circuit. I
can rematch two more lamps but before I do the thought occurred to me
if there was any practical easy way the equalise the voltage accross
both lamps in order to compensate for any minute differences in
filament resistance. I think that the total current, (two lamps in
series) is about 5.0 amps. * Thanks for any suggestions. Lenny

Nothing to do with the post Lenny - just a casual question about your nic !
:-)

I never knew who or what Klem Kedidlehopper was, until I was in a movie
memorabilia shop in Vegas last week. There was a suit on display that
claimed to have been worn by this guy on his TV show (I'm assuming he is a
left-pondian comedian. Me being right-pondian, he's not one that I know).
But anyway, here's the thing. They had his name spelled with a "C" as in
Clem Kedidelhopper. Is that wrong of them, or is your spelling with a "K"
some comedic twist that I'm missing ?

The military battery system consists of two 12volt batteries in
series..Every load in the vehicle is connected between 24 volts and
ground. There is no 12 volt load connected "halfway" between
batteries. Electrically the charging system treats the two separate
batteries as though they were one 24 volt battery. I like the idea of
connecting each lamp to each battery, ( a three wire circuit), however
in the event that a cell in either battery goes dead, the imbalance in
voltage across the two batteries would be far greater than that
created by a weak filament.

Klem Kedidelhopper was a comediene of 1950's vintage I think.that he
was the brain child of Red Skelton. When my son persuaded me to open
an email account many years ago after I repeatedly told him that I
would never have any use for one I had to pick a screen name.
Never really thinking that this would ever even go anywhere and not
fully taking this whole computer thing seriously at the time anyway, I
chose the name of one of my favorite TV characters. Well these days I
use email a lot, Klem is still on the job, I still think computers are
a royal pain in the ass, and surprisingly most people have no idea as
to who he was. Lenny
