Capacitor On Coil?

Go to solution Solved by TobyB,

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?



(I ran a Pertronix for a bit, but am currently using points FWIW) Tom

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.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
