Balis Risester
On my '57 Ford Ranchero / 460 c.i. With Point ign. has on the fender a ceramic gizmo, woth a prong out each end. 1 - going to the ign. the other to the points. Is it an amp drop. if so- From ? to ?

Ballast Resistor
It is used to lower your voltage going to the points. It's dropped down from 12V. I'm not real familiar with Ford points Ign. systems, but I'm sure one of the other members might have a reasonable voltage # on the downstream side of that resistor. Hope this helps a little.

It's a ballast resistor, it reduces the voltage going to the points. A straight 12 volts will fry the points in short order.

The voltage is dropped to save the coil not the points. The condenser will keep the points from burning but the coil will get too hot running on 12v all the time. 12 volts goes to the coil only at start-up. The second wire on the solenoid sends 12volts to the coil for a hotter spark at start-up but then runs on 9volts the rest of the time.
Hope this helps Scholman

(BALLAST - RESISTER)
THANKS TO ALL OF YOU! When I pulled the plugs on one side they were moist with gas. My Choke needs to be fixed. Which wire from the Alt. goes to the choke?
