Both designs operate in a similar manner:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When the driver turns the ignition key to the &ldquo;start&rdquo; position, the solenoid engages a plunger, which, in turn, acts on a lever fork inside of the starter.<\/li>\n\n\n\n<li>The fork then pushes the starter&rsquo;s pinion gear into mesh with the ring gear on the engine&rsquo;s flywheel or flexplate.<\/li>\n\n\n\n<li>The solenoid&rsquo;s plunger pushes a disc against a set of contacts. Current flows from the battery to the starter once the contacts connect.<\/li>\n\n\n\n<li>Current then passes through the starter&rsquo;s insulated brushes, which ride on the commutator portion of the armature, before entering the field coils and the armature windings.<\/li>\n\n\n\n<li>The current flowing through the field coils and armature creates a magnetic field that causes the armature to spin.<\/li>\n\n\n\n<li>The commutator continuously switches the polarity of the circuit to keep the armature spinning in the same direction.<\/li>\n\n\n\n<li>If the starter has a direct drive, the spinning armature turns the pinion gear directly. But if the starter has a gear drive, the armature drives a set of gears that turn the pinion gear.<\/li>\n\n\n\n<li>In either scenario, the starter&rsquo;s pinion gear rotates the engine&rsquo;s flywheel. Because the flywheel is bolted to the engine&rsquo;s crankshaft, the internal engine components (i.e., pistons, camshaft, etc.) are set into motion.<\/li>\n<\/ul>\n\n\n\n<p>Once an air-fuel mixture and spark are added to the equation, the engine begins to run.<\/p>\n\n\n\n<p>The driver can then move the ignition key to the &ldquo;run&rdquo; position to disengage the starter motor. If the driver fails to do so, the starter has a one-way clutch that will allow it to freewheel. That way, the starter doesn&rsquo;t get damaged by the spinning engine.<\/p>\n\n\n\n    <div class=\"ai-summary-widget\">\n\n        <div class=\"ai-summary-grid\">\n\n            <div>\n                <div class=\"ai-avatar\">\n                    <figure>\n                        <img decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/q_auto,dpr_auto,f_auto\/carparts\/blog\/widgets\/ai-summary\/ai-bot\" alt=\"AI robot\">\n                    <\/figure>\n                    <span>ELI5<\/span>\n                <\/div>\n            <\/div>\n            <div>\n                <p>When you turn the key to start your car, a small motor called the starter helps make the engine go. The starter has a little helper called a solenoid that pushes gears together to get the engine turning. The starter spins really fast, using power from the car&rsquo;s battery. This spinning makes the engine&rsquo;s parts, like pistons, start moving. Once the engine starts, the car runs on its own, and you can let go of the key. If you forget to turn the key back, the starter has a special clutch that keeps it safe from breaking. The starter&rsquo;s job is to get the engine going so your car can drive.<\/p>    \n            <\/div>\n\n        <\/div>\n\n        <div class=\"ai-summary-tooltip\">   \n            <p>Not everyone is an auto repair expert. <strong>ELI5 (&ldquo;Explain Like I&rsquo;m Five&rdquo;)<\/strong> provides layperson-friendly explanations of complex automotive concepts, systems, &amp; parts, so you can fully understand their importance.

But what about the rest of the starting system?<\/p>\n\n\n\n<p>Starting circuit operation is fairly straightforward. When the driver turns the key to the &ldquo;start&rdquo; position in a typical starting system, battery voltage flows from the ignition switch to an underhood relay.<\/p>\n\n\n\n<p>As long as the <a href=\"https:\/\/www.carparts.com\/neutral-safety-switch\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"neutral safety switch\">neutral safety switch<\/a> is in the park position (or the clutch safety switch is closed), the relay closes, allowing voltage to flow to the starter solenoid.

Instead, these switches act as inputs to control modules&mdash;usually the body control module (BCM) and the transmission control module (TCM).<\/p>\n\n\n\n<p>The BCM and TCM communicate the position of the switches to the engine control module (ECM) over a data network. If the conditions are correct, the ECM then operates the starter relay to supply power to the starter solenoid.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Different Starter Solenoid Terminals?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"614\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/starter-solenoid-terminals-1024x614.jpg\" alt=\"starter solenoid terminals with labels\" class=\"wp-image-24373\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/starter-solenoid-terminals-1024x614.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/starter-solenoid-terminals-300x180.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/starter-solenoid-terminals-768x461.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/starter-solenoid-terminals-150x90.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/starter-solenoid-terminals.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Starter solenoid terminals: B = battery terminal, S = start terminal, M = motor terminal<\/figcaption><\/figure>\n\n\n\n<p>Many DIYers wonder: What wires go to the starter solenoid? Typically, a starter-mounted solenoid has three terminals with three connections:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The &ldquo;B&rdquo; or &ldquo;battery&rdquo; terminal: The terminal that connects the solenoid directly to the positive battery cable.<\/li>\n\n\n\n<li>The &ldquo;S&rdquo; or &ldquo;start&rdquo; terminal: The terminal that receives power from the ignition switch.<\/li>\n\n\n\n<li>The &ldquo;M&rdquo; or &ldquo;motor&rdquo; terminal: The terminal that attaches to the cable that connects to the starter motor.<\/li>\n<\/ul>\n\n\n\n<p>When the driver turns the ignition key to the &ldquo;start&rdquo; position, voltage is sent to the starter&rsquo;s &ldquo;S&rdquo; terminal. That voltage energizes the solenoid&rsquo;s electromagnetic windings.<\/p>\n\n\n\n<p>The windings then create a magnetic field that pulls the starter&rsquo;s plunger, forcing it to push a disc against a set of contacts. Those contacts attach to the solenoid&rsquo;s &ldquo;B&rdquo; and &ldquo;M&rdquo; terminals. Once the two terminals have an electrical connection, current can travel directly from the battery to the starter motor to crank the engine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQs About Wiring a Starter<\/h2>\n\n\n\n<p>A licensed mechanic is your best source of information about wiring a starter. If you want to learn more but don&rsquo;t have time to stop by your auto repair shop for a consultation, you might find the answers to these questions helpful.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Where Does the Starter Get Power?<\/h3>\n\n\n\n<p>The starter draws power from the battery through thick cables that can channel high electric current.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Wire Goes Where on a Starter Solenoid?<\/h3>\n\n\n\n<p>Two cables usually connect the battery to the starter: a red wire and a black or greenish-yellow one.<\/p>\n\n\n\n<p>The red wire connects the battery&rsquo;s positive terminal to the solenoid, while the other cable connects the battery&rsquo;s negative terminal to the motor.<\/p>\n\n\n\n<p>The colors vary depending on the vehicle&rsquo;s year, make, and model.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can You Connect a Starter Directly to the Battery?<\/h3>\n\n\n\n<p>Yes, you can. It&rsquo;s one of the ways mechanics check starters. They bypass the car&rsquo;s electrical system using jumper cables.<\/p>\n\n\n\n<p>First, they turn off the ignition and put the transmission in park mode. Then, they connect one end of the positive cable to the battery&rsquo;s positive terminal and the other end to the starter motor&rsquo;s positive terminal.<\/p>\n\n\n\n<p>Mechanics determine issues based on how the parts react. For example, if the starter cranks the engine, there might be something wrong with the cables or relay.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Happens If You Wire a Starter Solenoid Wrong?<\/h3>\n\n\n\n<p>A high electric current might surge through the solenoid due to faulty control or starter circuit connections. The heat could merge crucial parts and lead to starter solenoid problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Happens If a Starter Is Not Grounded?<\/h3>\n\n\n\n<p>Your car will struggle to start if there&rsquo;s loose ground to your starter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Where Does the Starter Ground Wire Go?<\/h3>\n\n\n\n<p>A starter ground cable often goes from the starter housing to the transmission case and the engine block.
