The ignition switch in a motor vehicle is the master electrical component used by the operator to first, run and turn off the vehicle. The chief purpose of the switch is to permit the operator to safely appoint the ignition organization and activate the electric starter. Replacement of the ignition switch becomes necessary when you have trouble turning on the electric organisation, or if the starter fails to stop turning afterwards the motor has started.

Step 1

Locate and identify the pins on the back of the ignition switch, There should be four terminals marked "BATT" for Battery, "ST" for Get-go, "IGN" for Ignition, and "ACC" for Accessory. Some switches may use a different letter of the alphabet or number code, so check with the manufacturer of the switch to properly identify the terminals.

Step 2

Disconnect the cablevision from the negative battery terminal using an adaptable wrench. Place the positive ability lead to the ignition switch. The power lead is ordinarily a thick blood-red wire and stays energized at all times. Install the correct terminal end on the power lead wire and crimp it securely with a concluding multi-tool. Connect the power lead from the battery to the "BATT" terminal of the switch. Some ignition switches use a cantankerous-tip screw to secure the wires, and some employ spade clips on the wire ends. Determine which i is appropriate for your ignition switch.

Step three

Connect the accessory lead wire to the "ACC" terminal of the ignition switch using the appropriate wire terminal. This wire energizes vehicle accessories such as the radio when the ignition switch is turned to the "ACC" position.

Step 4

Connect starter relay wire to the "ST" terminal of the ignition switch. The "ST" terminal only activates when the ignition switch is turned to the "START" position and is a spring-loaded momentary contact.

Stride 5

Connect the ignition wire to the "IGN" terminal of the ignition switch. This is the main final that is used for vehicle ignition, wipers, accessories and other operating features. This is the normal "run" position of the switch.

Reconnect the cable to the negative battery terminal.
