What connects to the top of the distributor cap?
The distributor cap is the cover that protects the distributor’s internal parts and holds the contacts between internal rotor and the spark plug wires. The rotor is attached to the top of the distributor shaft which is driven by the engine’s camshaft and thus synchronized to it.
What gives power to the distributor cap?
The plug which is pointing right at you provides power for the electronics inside the distributor (green box). This is low voltage power. To power the spark plugs, the distributor is powered from a coil through the cap.
How many wires go to the distributor?
They usually required only three wires: the spark plug wire, the power wire and the ignition switch wire. Ignition coils of this type are usually a little larger than a soda can and are heavy because of the metal core and the field coil windings. These coils are also filled with oil for temperature control.
Where does the Black Wire go in a capacitor?
In some capacitors, the black wire is connected to neutral while the brown wire is connected to the active, leaving the blue wire to go to one part of the run cap. The other part of the cap goes to the active and brown wire.
Where does the wire go on a dual round capacitor?
On the dual capacitor, you would have one wire that would come from the contactor, the power wire and attach to the “C” common connection on the dual capacitor. The Fan connection on the capacitor would go to usually the brown wire of the fan motor and the Herm connection on the capacitor would go to the compressor’s “S” start winding.
What kind of capacitor do I need for a distributor coil?
Almost all automotive distributor coils use a 0.25-0.29 microfarad capacitor. The operating voltage rating should be no less than 600 volts DC. There are now capacitors available in the 0.25 microfarad range rated at 630 volts AC.
How do you connect a capacitor to a rotor?
Locate the negative terminal of the capacitor, and attach it to a switch. The start connection commands a series of connections up to its winding. If the motor has a switch on the rotor with a pair of connections that are closed when the motor is not running, take one wire and put it on the start cap, and then connect the cap to that contact.
