?? Positive - Negative Ground Coils ??
I have some coils I wanted to use on either the Model A or My 1947 Flatty V8 Pickup.
The Coils have three terminals -- besides the Hi Voltage.
They are marked; ( + ) , ( - ) , and ( DIST ) !
I get 0.25 ohms between the + and - terminals.
I get 16.20 Kohms Between High Voltage and ( + ) or ( - ) .
These sound okay.
BUT THE TERMINAL MARKED ( DIST ) seems to measure open to everything !!!!!!!
What may the " DIST " TERMINAL before ????????? Anyone KNOW ???
I may cut one open ---------- good ole Auction fines !!!!!!

I'm working at confusing my self '''''''''''''''
I answered one question ---------- I cut open one of my NEW - auction coils ------- and the terminal marked " DIST " is going no where ----- which my infinite resistance reading said.......
Now the terminal marked " + " is the common one between the low voltage primary winding and the auto transformer - Hi Voltage secondary ---------------------------------------
Sooooooooooooo in wiring up for ignition I could either use points to switch the ground point either at the + or - terminal -- thereby getting the proper NEGATIVE High Voltage Pulse to the Plugs ------------Hummmmmmmmmmmmmmmm
which is the best way ????????????
I've seen other discussions on this topic ----but ??????????????
Thanks ??? John gettin ready for 'back tp fifties'

Of course if you are running 12 volt negative ground, you hook the points the negative, and the ignition switch and ballast resistor to the +.
I seem to remember burning up my original coil on my 53 f100(when it was original 6v pos ground) and I took a regular coil and hooked the points to the + and the hot wire from the key to the negative, and it worked fine.
