..until you notice the fuel consumption...if you have a heavy foot on gas pedal.

Just found a nice simple tool for this kind of thing;

A Java based circuit simulator, brilliant piece of kit with oscopes and everything :)

Hi,

Late reply, but I would actually recommend higher voltage caps. Crank conditions can produce rather high voltage spikes. You can actually get caps recommended for automotive applications, but they tend to cost a fair bit more.
Good good study, day day up!

The Farad capacity I want to use to get the desired fade down rate, only tend to come large voltages anyway :)

Unexpected expenditure (in the form of a new bed) has resulted in me pushing back any hardware projects for a while :(

I was reading up on capacitors.  You want to derate capacitors by 50% because they often fail.  In other words, you can put a 12 volt cap. on a 6 volt rail.

I think Wayne should make this thread sticky.  The first two posts from bloodline and Karlos are classic Amiga.org.  I luv it.

PS: I tend to agree with Karlos' appraisal.

Wired in a 4.7mF (24v) capacitor, looks magic (also added a 1ohm metal film resistor to give some current limiting to the capacitor).

@Karlos
Don't think they actually fade in unless you limit the current with a serial resistor. The battery can deliver plenty amps to load the caps, don't think it takes >100ms.
