Capacitor On Coil?


'76mintgrün'02

Recommended Posts

I recently took my new Bosch "black" coil off and put the old one back on. I had replaced it when I did my initial tune-up, after buying the car. I prefer the look of the old one and the fact that it says "made in Germany" on it. It seems to work just fine, so why not? The question I have is, what is this little capacitor for? Was it added to extend the life of the points?

Yes, it is bypassed during engine cranking to send full power to coil by a relay. Otherwise it will shorten the life of your points if it is removed. It should be 1.1 ohms. Never used it with a blue coil. If you replace your black coil with a red or silver one the label will say use a 1.8 ohm resistor otherwise the coil will overheat. This has happened to me.

Thank you Toby, it seemed sort of randumb, but thought I would ask. 

 

HBChris, my car has the resistance wire in place of the ballast resistor, which I bypassed to run the Pertronix unit.  Back on the old wire now and running points.  I am pretty sure this little lentil is unrelated, but thank you for your input.
