Bobby-Lee, look I think you got that sentce messed up hon. It should
say, If I understand anything other than basic car audio (which I
don't!) I should know what you mean (but again, I don't!).

Why do you refuse to answer the question? Here it is again: do you know
what the 20v rating on a cap means?

Of course, you also think that a higher-capacity alternator makes it
harder to start the engine, so you can see why your credibility is a
little low around here.

Umm, a "20V capacitor" never charges up to 20V in a car. A
capacitor's voltage will *never* exceed the maximum voltage that's
applied across its terminals. So, if your car's voltage regulator
never allows the system voltage to go above 15V, then the capacitor
voltage will never exceed 15V. Using a 20V cap just provides more of
a safety margin compared to using a 16V cap. In most cases, a
16V-rated cap would be just fine anyway.

And a 3V cap won't survive very long in automotive use, unless you
wire five of them together in series to increase the overall voltage
capacity to 15V. Applying 12V (or more) across the terminals of a
capacitor that's only designed for 3V will probably cause the
dielectric material inside the cap to break down, leading to a
short-circuit.

i meant 3farad...or 2.4farad. only use those for daily driving....big
enough to help not too big to strain the battery...etc.

If you can find any of your old calendars from, say, 1987, I bet you even
have the day marked when you finally knew everything you needed to know.

Bob, you must be slipping. That last reply was some of the worst
backpeddling I've ever seen.

If you have a 1-wire alternator, the alternator doesn't even "turn on"
until the engine is up at idle speed or even higher. That's why you
sometimes have to "blip" the throttle after you've started the car to
get the alternator to start producing current. Of course, once the
alternator "turns on", it will continue to produce current until the
engine is shut off.
