Capacitor between grounds: Reason and how to decide the value
Its a NLswitchable part that is used for identification only (almost definitely). It appears that they use a capacitor to indicate what kind of board it is visually. On other boards, if the grounds were different on either side I''d say it was a ground connection but the ground is the same so it serves no purpose electrically.
Install Capacitor Before or After Distribution Block
I currently have all 4-awg wiring. I am just going to keep that to go to each of the T-blocks. Then, from those go 0-awg to a KX1200.1 amp and a KX600.4 amp for the power and ground. I am going to swap the current 4-awg ground to a 0-awg from the block. My question is where should I put the capacitor? Before or after the distribution blocks?
grounding
The alternative would be to put a gap between these pads and the ground fill, and to connect directly decoupling capacitors to the inner ground plane with a via. Or maybe to create a local GND fill around the IC, which would be connected only to the inner ground plane with some vias.
Mod Garage: Three Ways to Wire a Tone Pot
On a tone pot, instead of sending the complete signal to ground, the capacitor only sends a part of the signal to ground. The capacitance of the tone cap determines the cut-off point of the high frequencies. A low-capacitance tone cap—3300 pF, for example—will pass the least amounts of high-end chime to ground. Thus, when you roll the pot ...

capacitor ground or not?
What my goal is: make light turn on after a time delay. from the answer this wont work. but i belive it will since 1k resistor will make the capacitor use about 1.5 sec to reach 12v wich my bulb needs before it even will turn on. but my main question was is this wiring correct. since capacitors have +/-. $endgroup$ –
Capacitors in Series and in Parallel
However, for polar capacitors, such as electrolytic and tantalum, the capacitors must be oriented in the circuit in the correct way. Polar capacitors, in series, must be placed so that the negative electrode of the first capacitor connects to the positive electrode of the second capacitor, and so forth for all capacitors in series.
