@DJDAudio2 ай бұрын
These can be tricky, one of the many hundreds of moving parts inside may be stuck or sticky! Depends how it is stuck, if the cranks goes all the way down and back up you just need to reset the total: On mine I have to hit just the 1 key far right side, crank it in, than hold down the TOTAL button with thump while pulling the crank down, than letting go with thumb as I continue the crank handle down, this will 'total out' the machine an clear the register! If the crank handle will not return, you may have a stuck key or too, you may need to try and push a few keys around the one that is down and try to work up the stuck one, this may free it up. If not you may have to pull the cover and look for anything caught in the mech, the old felt or old paper can get caught some times! Hope this helps!

I have an old Rockwell taxi meter in fairly good shape. 12 volt. Not a wind-up model. Has H41824 on the front. On the bottom is a 3 prong recessed male plug, presumable for connecting to the car power. There are 3 wires on the inside coming from this, Red, Black, and Yellow. I have a 12 volt power source I'd like to connect to see what happens but I'm not sure which prongs I should connect the 12V + and - to. Those 3 wires go to a Micro Switch with 5 terminals and other wires connected. The yellow wire goes to a connector labeled COMMON. The meter chassis itself could also be a ground since when I play around with continuity test on my multimeter I can get continuity sometimes. All confusing for me, sigh. The flag turns good and I tested the light bulbs and they are good too. So any help you could provide on connecting 12 volts, the + and -, (not in a car, just on my workbench) would be most appreciated.

This was a tough call on my part, the unit dates back to the 70's and is well past its serviceable lifespan. A replacement filament for this unit is also $500+ And they will not referb one if you do not have an expensive service contract with them. That and taking it apart and contaminating it like I did would mean months of decontamination and time to bake it out and pump it back down to a usable vacuum conditions. So I felt it was better served to take apart and be able to show the inside of this unit as an educational tool or entertainment for those who are curious. For not every day you get to rip open a million dollar machine just to explore for fun! I do plan to use parts of this in many other projects so it was by no means a waste of hardware! The last scope I took apart I used to make my own liquid nitrogen maker, and a fusor! Hope that helps explain my motivation for this! ... P.S. Part of the agreement for getting items like this is often that they can never be 'used as intended' again aka destroyed.

@narmale6 ай бұрын
probably has to do with the effect of any protrusions creating a localized induced magnetic field through eddy currents which would throw off the magnetic focus
@DJDAudio6 ай бұрын
My best guess for the polish. The very high voltage this runs at requires the smoothest surface possible, for electrons tend to concentrate at points ( Why lightning rods work!, and why you get static shocked on whatever part of your body sticks out! ) A rough surface is full of very small points and can bleed off charge from the system or ( leak ) So in a way making it smooth is like making a 'water tight' vessel for the electron gun.
