The starter on a Nissan Sentra as of 2014 is connected to the battery terminal via two thick cables, although its exact location differs depending on the model of the car. The cable attached to the positive terminal on the battery links directly to the starter. The cable linked to the negative terminal leads to the engine block, which is next to the starter.Continue Reading
As of 2014, the starting system in a Nissan Sentra is activated when the ignition key is turned to the "on" position. This action directs voltage from the battery through the starter's control circuit and triggers the starter relay, also referred to as the solenoid. The solenoid moves the gear for the starter forward, which engages the crankshaft and starts the car.
Nissan ignition systems typically use a coil-on-plug or distributor-type system to operate the engine. Component system failures are often attributed to the ignition control module in a COP system; the distributor cap or rotor may cause a failure if the car is distributor-equipped. An inoperable fuel pump or blown head gasket can cause starting problems as well.
Many of the first automobiles used hand cranks for the ignition system; turning the handle moved the crankshaft and started the engine. Other vehicles used wind-up springs, which used spring tension to start the car's engine.Learn more about Car Makes & Models
