Whether you are connecting to the battery, amp, or a distribution block of some kind, you need to connect the positive terminal of the capacitor to the positive terminal of the other component by running a wire between them. Eight gauge wire is usually recommended. Connect the capacitors negative terminal.

Can you connect a capacitor to a battery?

Capacitors store energy by holding apart pairs of opposite charges. If you attach a capacitor (with capacitance C) to a battery (at voltage V), it will slowly develop a charge on each plate ( Q) as electrons build up on one plate and then exit the other.

Can a start capacitor be wired backwards?

In an AC circuit it does not matter if a capacitor (intended for that circuit) is wired backwards. In a DC circuit, some capacitors can be wired backwards, others cannot.

What happens if the battery is disconnect from the capacitor?

The capacitor gets charged to the battery voltage before it is disconnected from a battery. When the battery is disconnected from the capacitor, the charge stored in the capacitor remains the same. The voltage across the capacitor also will remain the same.

What does a 12v capacitor do?

Adding Capacitors Capacitors store electricity as instant power available for your amplifier. If the amplifier draws more current than is available from the electrical system directly, the capacitor covers the difference up to its stored capacity. The battery is not overloaded and the car voltage remains steady.
