Volvo Penta Ignition Switch Wiring Diagram – Let’s start by looking at the various types terminals found in an ignition switch. They include terminals for the Ignition switch, Coil, and Accessory. Once we understand the function of each kind of terminal, we can then identify the parts of the ignition wiring. We will also talk about the functions and the Coil. After that, we’ll turn our attention to the Accessory terminals.
Terminals for the ignition switch
An ignition switch has three separate switches that feed the battery’s current to different locations. The first one supplies power to the choke when it is pushed. The third is the position of the ignition switch’s ON/OFF. Every manufacturer has its own color-coding system, which we’ll go over in a separate article. OMC follows this system. An additional connector is included in the ignition switch to allow attaching a Tachometer.
While most ignition switch terminals are duplicated, the number may not match the diagram. The first step is to check the continuity of all wires to make sure they’re properly plugged into the ignition switches. A cheap multimeter can assist you in this. After you’re sure that all wires are running in good harmony and you are able to connect the new connector. If your vehicle has an ignition switch that is installed, the wiring diagram will differ.
It is important to understand the ways in which the ACC outputs and the auxiliary outputs function in order to connect them. The ACC and IGN connectors are the default connections for the ignition switch. The START, IGN, and ACC terminals are primary connections for radios or stereo, the START/IGN terminals are the most important ones. The ignition switch is the engine’s on/off button. Older cars are identified by the alphabets “ACC”, “ST”, (for individual magneto cables) at the ignition switch terminals.
Terminals for coil
To identify the kind of ignition coil, the initial step is to learn the terms. A basic diagram of the wiring will reveal a variety of connections and terminals. The coils are equipped with a particular operating voltage. The initial method of determining what type you’re using is to test the voltage on S1, the primary terminal. S1 should be checked for resistance to determine if the coil is type A, B and/or C.
The chassis’ negative needs to be connected to the side of low-tension. This is also the ground on the diagram of the ignition wiring. The high-tension side supplies the spark plugs with positive. To reduce the noise the body of the coil must be connected to the chassis. But, it’s not necessary to connect the coil electrically. You will also see the connections of the negative and positive coil’s terminals on the ignition wiring diagram. Sometimes, a damaged ignition coil can be detected with a scan at an auto repair shop.
The black-and-white-striped wire from the harness goes to the negative terminal. The white wire is the other one. It is black with a trace, and connects to the positive terminal. The black wire connects to the contactbreaker. If you’re not certain about the connection between both, you can use an old paper clip to take them from the housing of the plug. Make sure that the terminals aren’t bent.
Accessory terminals
The diagrams for ignition wiring show the wiring used in the power supply of the vehicle. There are generally four colored terminals for each component. The red color represents accessories, yellow represents the battery, and green for the solenoid for starters. The “IGN” terminal is used to turn on the car, operate the wipers and other functions. The diagram shows the connection between the ACCas well as ST terminals.
The terminal called BAT is the location where the battery is. The electrical system won’t start if the battery isn’t connected. The switch also won’t turn on without the battery. A wiring diagram can show you the location of the battery of your car. The ignition switch and battery are connected by the accessory terminals. The BAT terminal is connected to the battery.
Certain ignition switches have an accessory setting where users can adjust their outputs as well as control them without having to turn on the ignition. Some customers want the auxiliary output to be operated independently of the ignition. You can utilize the auxiliary input by connecting the connector to the ACC terminal. This convenience feature is great however, there’s one distinction. A lot of ignition switches can be configured to be in an ACC location when the car has moved into the ACC position. They will also be in the START position after the vehicle has been moved into the IGN position.
