Dyna coil question

Bought green 3ohm coils from z-1 (Thanks Jeff)

Instructions read like this
for breaker points, the 5 ohm coils should be used or the 3 ohm coils can be used and a 1 to 2 ohm ballast resistor in the 12 volt line going to the coils.
I also bought wires. Do I need a resistor in the power line to the coils, yes Im still runing points. I think of this because Ive heard that the original plug caps had resistors.
Any thoughts are appreciated.

Ignore all that. Just replace the coils one per one. There is already a ballast resistor in your circuit. You can leave it in or remove it. The system is set up for 3 Ohms including the ballast resistor. If you remove the resistor you will have a better spark. The coils they you are removing ate approximately one and a half Ohms and so is the ballast resistor. together they make up about 3 Ohms. If you use the resistor in the circuit your points would last forever. The resistor is there to prevent arcing at the points.

Did you buy copper core sparkplug wires/high tension leads, or the graphite core ones?

My understanding is if you use copper sparkplug wires, you'll need the resistor caps, if graphite cored wires are used, then caps without resistors can be used.

I believe the resistors reduce the spark energy enough to not bother radio's or T.V. sets.

That is if you have a TV set on your bike. :lol: I run a GPS and a digital camera with solid core wires and no resistor caps and have no interference at all. I don't run resistor plugs either. But that is with an electronic ignition.

I bought the graphite core For the possibility of electronic upgrade later. So Im good to go then? Have to wait till next week, off to the lake Friday.
Stay safe and have a great holiday weekend
Remember why we have it. Honor our vets. Say Thanks

Ps I plan on reinstalling my Jammer with radio.
Bought it like that Nastalga

The condenser is to reduce arcing at the points, and to give the points a little bit of time to open up before the primary voltage spikes. Without it, the points would arc a lot and bleed off the spark energy before the plugs were able to spark.

The resistor is to reduce the current in the points to prevent them from heating up too much. If the points get too hot, too much metal transfers during the arcing at the points. Reducing the metal transfer keeps the points working longer.
