Starting Problems: Common Auto Electrical Causes

The electrical system is essential for the operation of the vehicle so related problems can be frustrating. It is important to identify anomalies and general problems in the module to facilitate early repair. The starter is typically an electric motor which is responsible for initiating the engine's operation by drawing electric currents from the battery.

If this component is not functioning properly, your vehicle will be ineffectual. There are diverse causes of no-start problems; some are simple so you can resolve them at home while others require professional assistance. Here are the most common auto electrical sources of starting hitches:

Battery Problems

It is recommended to start troubleshooting no-start problems by examining the battery. The module is responsible for providing the electrical current needed to start the vehicle so lack of power will prevent starting. A dead battery is the most common and obvious issue so use a battery tester to measure the cranking amps. If the damage is extensive and permanent, the state of charge will be at zero percent.

Alternatively, you can assess the problem indirectly by utilising the jumpstarting process. If the vehicle starts immediately, your battery is dead and you should purchase and install a new one. You should also check the battery connections for signs of corrosion and grime especially if the component is relatively new. Clean the exposed post terminals and then try starting your vehicle again.

Faulty Ignition Switch

The vehicle will not start if the ignition switch is faulty so you should explore this option if your battery is functional. Turn your keys in the car to the ON position but not far enough to start. The warning lights on the dashboard should light up; if not, the ignition switch is damaged.

If these lights turn on, twist the keys to the start position and study their response and that of the headlights. The lights should turn off and turned on headlights should dim or altogether turn off. If this does not happen, you will need to replace the ignition switch to restore the starting function.

Starter Connection Problems

The electric starter motor is exposed to the elements therefore it is susceptible to corrosion. The residue material from the reaction can act as an insulator which interferes with the starter connections. It is advisable to engage an auto electrical technician for this type of troubleshooting.

However, you can also use a circuit tester to examine current transmission when the key is turned. If there is electrical current but the starter is stationary, replacement will be necessary. To learn more, contact a company like Drive-in Auto Electrics with any questions you have.
