My understanding is that the old ballast resistor readings were made before you cleaned the points. Reducing the resistance across the points by cleaning them will increase the voltage drop across the resistor. (Kirchhoff’s Voltage Law)
If you want to compare your old and new resistors, set your multimeter to ohms and check them that way.
Good comment....I should clarify.
1) I don’t recall at what point I cleaned the points. Probably before taking any of the readings in the original thread....some weeks ago.
2) The voltage readings of the two different resistors took place just last night (on the firewall of the truck). All other variables should be the same. The old was taken before removing from the truck. The new was taken after installing on the firewall. I will measure the resistance of each disconnected from the system as well.
