Some of you that have gotten to know me, (I didn’t say like me) since I joined the forum a little less than a year ago, know that I have this insatiable curiosity, this “need to know everything” that crosses my path. I’m part Scotsman and part Irishman, one part means that I’m a real cheap skate and the other part means that I’m a real bullheaded. Usually the two halves manage to work together to find a way of fixing things with out parting with the green, of course sometimes they work against each other and the bullhead ends spending more of the Scotsman’s money than he should.
Anyway that’s why I just have to fix up these parts as much as I can on my own rather than simply replace them with a rebuilt or reproduction. A positive side affect is that I learn a lot. I’m already 65 and I’m only scratching the surface, so much to learn!
Stu, I got a chance to read your excerpt and I see what you guys are referencing to. I've never having had the opportunity to actually do an autopsy on an AD fuel gauge so I really don't know what kind of a movement it has in it. I was assuming that they were simply an inexpensive D’Arsonval or Permanent Magnet Moving Coil movement using an internal shunt.
I’ve also down loaded a few other articles one of which is by Randy Rundle describing the movement used in fuel gauges. From his discription this meter movement cannot quite be considered a true electrodynamic meter movement but I think it’s in the same family, I’m still looking for that answer.
By the way, what was that Detroit engineer’s name???
