![]() Most likely replacing one means replacing the other anyway. Similarly, a bad starter is likely going to require replacement. A loose battery cable connection is often the simplest of causes for a non-start.Ī bad starter solenoid means replacement is needed. RepairsĪ low or bad battery can be easily tested with a standard ohm meter or at any auto repair shop or parts store (they usually do this free of charge). Likewise, a bad battery would probably not be able to power the dash and headlights and if they were working, they would still dim during a start attempt. As another example, a bad starter would probably either make a grinding noise, a “spinning” noise, or the solenoid clicking noise. Otherwise, there would be some kind of action happening, even if it doesn’t start the car, that would denote other issues.įor example, when the starter solenoid is bad, it usually gives off a “clicking” sound as the power enters it from the battery and gets sent straight to ground instead of turning the starter. In the case of no sound, light dimming, or other problems, the problem is going to be either the ignition switch not sending the signal or the battery being unable to send the power to the solenoid. They keyswitch may not be sending the signal to tell the battery to send juice to the starter, the battery may not be able to send enough power to the solenoid to turn the starter, the solenoid may not be ramping up the power given to it, or the starter may not be functioning and able to turn. Now, thinking about that starting circuit, consider the things that could be going wrong to interfere with it. There are a few other things in the circuit, of course, depending on the car, its age, and what accessories or features it may have, but the circuit always has the above components working in that sequence. Turning the engine causes the pistons to rise and fall in the engine block, activates fuel and spark, and (hopefully) ignition of the engine so that it begins running on its own without the starter motor turning it. This turning is translated to the engine, which turns as if it were running (aka “cranking the engine”). The solenoid ramps up the power given to it and that power causes the starter motor to turn very quickly. The key turn completes a small circuit that tells the battery to release power to the starter solenoid. The process of starting the car begins at the ignition switch in the driver’s cockpit. ![]() The higher rate of electricity gives the starter motor more “oomph” to turn the engine over. This makes the water jet out the other side faster and further than it would have at its original pressure. Think of this process as a water pipe with a series of loops that get smaller and smaller in diameter, increasing the water pressure without increasing the amount of water flowing through. The starter’s solenoid (which is usually attached to the starter as the “hump” on its back or side) takes the power supplied by the battery and ramps it up to make it stronger so the starter can turn quickly. It is made to carry the largest amperage load the battery can produce (often defined as its “cranking amps”). This starter lead will be the thickest cable running from the battery’s positive terminal. The red (positive) will have a thick lead that goes directly to the starter solenoid, sometimes via an electronic control box. The black (negative or ground) will usually lead to a ground on the vehicle’s metal frame. The battery will have red and black (positive and negative) terminals. ![]() ![]() In most cars, this is a standard 12 volt lead-acid battery, usually located in the engine compartment at one corner – most commonly against the firewall on the right (passenger’s) side. The starting circuit begins at the vehicle’s battery. If you’re studying this in college and look for assistance, we advise you to check out, a reputable assignment writing company. This will show you where the disconnect could be to explain why you are not getting “crank” (starter turning the engine). So, to diagnose the problem, you’ll first need to visualize the starting circuit. Your sense of sight, hearing, touch, and smell are the primary tools you need in doing this. This way, you can narrow down the probable causes of why your car isn’t starting. But whatever the causes are, it’s crucial to know what to do if your car won’t start and how you can diagnose it quickly.ĭiagnosing your car is vital. These might be due to loose electrical connections, a dead battery, faulty spark plugs, a bad alternator, and other unfortunate situations. Generally, there can be many reasons why your car might experience these problems out of nowhere. This is especially true if you have no idea how to handle the situation. However, having starting issues in the middle of the road can be devastating. This is a relatively common phenomenon and it can happen to any car, no matter its age or mileage.
