Two reasons to have a capacitor in any circuit: First-----to give any starting circuit an extra jolt of power when first firing up the circuit. A good example is your home A/C unit. There is normally a huge capacitor wired into the starting circuit. It's that great big huge oblong thing attached to some obscure place that has two wires going into it. Capacitors store power and only discharge when called upon----or some stupid idiot puts his finger across the terminals. :-) (Not that I have ever done something like that!!! LOL) Second-----To stop any electrical interference with your radio. Note that on the Delorean there are many capacitors wired into any circuit that is in continuous motion, when the circuit is energized. Ex: the A/C fan, the coil, the fan speed switch, etc. Josh's car even had two capacitors wired into the radio circuit (sometime) and the only reason I can figure out why is because the PO didn't want to take the time to figure out what the real cause of his static was. My thoughts on your original question are that the engineers decided they needed a capacitor in the idle speed circuit and this was a good place to put it as any. Anybody else have any other thoughts?? Now, just to enlighten everybody----Josh's car had a two wires, under the consol, beside the drivers right knee that were black and light green/white, but they had been cut off at the connector and taped over. This puzzled me for a long time before I finally figured out the problem. Anybody want to give it a try. The answer will follow tomorrow, for anyone that is interested.
