 However Peter has the Pertronix installed, so instead of protecting the points, the ballast resistor protects the Pertronix from burning out, right? It is a 1.6ohms resister. And you can tell that everything is doing it's job by the coil not getting HOT but just WARM....and also using a voltmeter for a specific reading?

Speaking of ignition wiring, it was written:?

Easier starting.?

The 'run' position of the ignition switch provides voltage thru the?

ballast resistor (B/W). The coil then 'sees' about 6 volts during normal?

operation. More importantly, this also limits current thru the points?

(without the ballast resistor you'll likely burn out the points).?
?

The 'start' position of the ignition switch not only provides voltage?

to the starter solenoid, it also provides voltage directly to the coil?

(Y/W). This full voltage provides for a more powerful spark to help?

ignite a cold fuel mix (and halps compensate for the battery voltage?

dipping during the start cycle - the load of the starter will pull the?

voltage down to 10 or fewer volts. That's why the lights dim when you're?

cranking).?

BTW, early Roadsters don't have this bypass circuit.?
