New distributor/elelctronic ignition/coil
Hi guys,
Summer is finally over here in Australia so it's time to start working on the Dart again.
I'm in the process of installing a Summit Racing Electronic Mopar Distributor (SUM-850003) and a MSD Blaster 2 Ignition Coil (8203), but I ran into a few problems. I'm no electrician so it's all very puzzling to me.
My current setup is the original points distributor with a very old looking Lucas BA7 coil, no ballast resistor anywhere. This brings me to my first question:
The RUN wire in the + terminal on the Lucas coil read 12V on the multimeter. I then measured the coil's resistance and it read 1.5ohms... so my poor understanding of electrics is telling me this coil should have burned a long time ago (shouldn't 1.5ohm coils run at 6-9V?)... Can anybody explain how this thing still works?
Now for the new setup. This is what I have to install:
These are the instructions that came with the ignition/distributor kit:
The main question is:
I know I will have to install a ballast resistor, but I can't figure out which. As you can see from the picture above, both the ignition/distributor kit and the MSD coil came with a ballast resistor each. They are 0.8ohms in the Blaster 2 kit, and 1.25ohms in the ignition/distributor kit.
So starting from the fact that I currently have 12V on the RUN wire, can somebody please explain what this installation should look like?
Any help would be greatly appreciated.
Cheers!
