65 Dart 273 Commando Ballast Resistor

A couple of comments.
- post #7 & 9 have incorrect info.
- measuring very low resistances [ less than a couple of ohms ] will give misleading results with a std DVM because they are not very accurate at low ohm readings. I have a special 'low ohm' DVM that is specifically designed to measure low resistance & sub 1 ohm resistances.
- using measured coil resistance etc to select the bal res resistance does not work because in operation the system is not operating 'statically'.
- the numbers quoted in my Motors Manual for 1973 Chry V8 engines is as follows: ign current draw, engine idling 1.9 amps, coil pri res 1.4-1.5 ohms, bal res 0.5-0.6 ohm.
