Here is a more detailed explanation of the Volvo 740 1990 Regina ignition diagram:

The battery is located in the engine compartment. It is a 12-volt lead-acid battery. The positive terminal of the battery is connected to the starter motor, and the negative terminal is connected to the chassis.

The starter motor is located at the front of the engine. It is a 12-volt electric motor that turns the engine over. The starter motor is activated by the ignition switch.

The ignition switch is located on the steering column. It is a rotary switch that has three positions: Off, Run, and Start. When the ignition switch is turned to the Start position, it sends a signal to the starter motor.

The distributor is located on the top of the engine. It is a mechanical device that distributes the spark from the ignition coil to the spark plugs. The distributor is driven by the camshaft.

The spark plugs are located in the combustion chambers of the engine. They are responsible for igniting the fuel in the cylinders. The spark plugs are connected to the distributor by spark plug wires.

When the ignition switch is turned to the Run position, the ignition coil sends a high voltage spark to the distributor. The distributor then distributes the spark to the spark plugs. The spark plugs ignite the fuel in the cylinders, and the engine starts.

If you are having problems with the ignition system of your Volvo 740 1990 Regina, it is important to consult a qualified mechanic. They will be able to diagnose the problem and make the necessary repairs.
