I really enjoy your videos and the animations you use to explain and simplify understanding of the subject matter. Last time I "repaired" a starter motor it was as follows; the loud click from the solenoid could be heard but then nothing, battery was fine so I removed the motor for bench testing. It turned out that the contactor plate/ring was not making the contact required for the electrical motor so bent the plate to ensure good contact, reassembled and re-fitted the assembly.

You can diagnose a possible faulty starter motor by measuring voltage of the thick wire of the starter when you have someone turn the key all the way to start. You can also jump the 12 Volt signal "S" post of the solenoid to the large post going to the starter with a piece of wire or metal object to test for a faulty solenoid.
Honestly you guys are the best.the videos you make is very educative i donot know how to thank u guys for what i have learnt all this while from you.please keep it up
My boat won't start and there is an electric issue. As it's not accessible easily, I find it very helpful to see this an find out what to look for. Inboard engines are diesel engines as well, they all work the same more or less. So thank you for helping me out with this very, very in detail video
I'm confused and lack a bit of electrical knowledge. Why does the pull-in coil not have a voltage difference on either ends when the contactor plates makes contact with the main terminal ends? Is it because the flow of electricity from the main battery is larger than what is supplied via the key ignition to the point where it just stops flowing?
The Inventor of this wonderful piece of kit , Charles F Kettering, and was fitted for the first time on a Cadillac in 1912 . Genius is word sometimes overused, not in this case . Great Video .
Got a brand new Explorer Titanium last March. It takes quite some getting used to, pressing a button to start it and shut it off. Frikkin cameras all over the thing too; traffic light engine shutdown (this feature scared my wife into thinking she broke it on the first day.
At 0:53 i can tell that engine is an NET turbo either 1.4 or 1.6 🤣 I know this because i literally rebuild 1 of these every week. Fun fact about them... the heads seem to blow quite easily and rubber the separates water from oil in the oil cooler can crack and cause engine failure😣
I used to work at a courier company full of sub-contracting owner operators. Failing starter motors were probably the most common failure. We would often crawl under the afflicted vehicle and bang the starter motor with a hammer while someone turned the ignition until the vehicle started and could be driven to the shop or the work be done for the day without turning the truck off. No idea why banging the starter motor worked, we just knew that it did and it saved many butts.
Banging on the stater would tend to free up the stuck carbon brushes which have become to short to fully reach the commutator. This arcing causes the brushes to stick in the brush housing and become stuck.
Exceptional explanatory vídeo. The lessons in your videos are extraordinary and of an absurd level of clarity in all the explanation that is passed to us allowing an understanding so facilitated that it is impossible to see only once. Congrats on the amazing works. 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻 Sorry for my English, I'm still in evolution.
Очень переживал, что расскажут поверхностно, без упоминания обгонной муфты и двухобмоточной катушки втягивающего. Рад, что ошибся. Респект за дотошность!
They were Bendix Starters in my day. The motor would throw a spinning pinion at the gear ring on the flywheel, using inertia to drive it forward on a spiral spline. There was a real possibility of causing wear and damage to the gear ring on the flywheel, after which the starter instead of engaging would make a loud shriek of clashing gear teeth. You could get the same effect by pressing the starter button/key when the engine was already running - guaranteed to do damage. Once the engine was running faster than the starter motor, the pinion would self disengage and run back down the spiral spline. There was a big spring on the shaft which helped this happen.
Ok but that would only make the pistons move, how do the spark plugs know they have to start working? also what happens when you turn your key off? Why the engine stops? Great video thanks for the insane quality!
The ignition system on petrol engines is also energised by the second stage position on your ignition key switch. The third position is to energise the starter motor. It is a momentary switch which means once the engine has fired up the ignition key springs back to second position. In modern csrs the ECU, ignition units and coil packs control the spark and timing. I learnt about cars when carbs, distributors rotor arms and HT coils and off course points were used.
At 8:00 min. When pulling coil is energised current is passing through motor coil then reaches negative. Does not it make humming sound of motor as it will try to rotate armature (not possible due to low current)?
I recently started seeing all the videos of this channel, and I have to say, YOU ARE GREAT PAUL! P.S. can you make a video on "how car AC system works"?
Question: Does the electricity for the pull in coil go through the windings of the motor to go back to the battery (negative side)? If it does, won't it start the motor itself already because it has a little potential voltage going through it?
Thank you very much, I understand every thing about turn starter the car , but I have a question about turning the car off , after using the starter gear to move the engine, it came back normal and the engine do the rest of the job , but when you switch the car off , which part of the car stop the engine and how?
If it doesn't start try tapping it a few times. If it doesn't work then turn the key on, push the vehicle and when you get some speed just engage second gear. It always works
Is there another way to explain the overrunning clutch and the rollers? That's the only part I can't get my head around. The engaging and disengaging of the rollers to protect the motor and pinion.
As far as I can tell, the pinion ger isn't attached to the shaft it spins freely. The overrunning clutch is what spins with the shaft. And as the clutch spins it's like a spinning rollercoaster on the rollers and they get plastered to the sides of their seats. The housing has ramps so as they get shoved to the side they run down the ramps and are shoved into the pinion gear and engage with it turning it. Then as the flywheel turns the pinion gear faster than the clutch the rollers are going to do what wheels do when you spin them; they run the opposite direction of the force you put on them. Do this put your hand in a big claw for the clutch, inside your claw put your other hand as a smaller claw for the pinion gear. As you rotate the big claw, imagine the rollers lagging behind and engaging. Then rotate the smaller claw faster then the big claw (engine is going faster the the starter). The small claw acts like the ground on the imagined rollers which spins them and drives them back up their ramps, disengaging them. Whoof! that was a mouthfull.
These videos are amazing. If you are ever on the subject of starter motors again, could you explain (or in this case show) how the solenoid uses the two different windings(pull in and hold in)
Nice video. Though missing many things. The power doesn't go directly from starter key to starter solenoid. Rather, power go from starter key to relay, through safety interlock and from there, it goes to Starter solenoid. Safety interlock will make sure that car will not start in reverse. Please correct.
When the contactor plate makes contact across the terminals, the pull in winding becomes 0v because both of it’s become connected to the positive of the battery?
What is the problem when you on the ignition the pinion doesnt disengage and when turning off engine it always on even the key is off ?.. but when you direct the starter into battery the engine runs okay and the pinion disengage smoothly also engine off is good
What happens when you try to start an already running engine? Is there any mechanism to protect the teeth in the starter motor or flywheel from damage?
The gear connected to the engine would be moving faster than the starter motor gear, so the little rollers mentioned at 6:20 would not engage. They stop the starter motor from getting damaged once the motor is running.
Since the engine/flywheel is spinning several times faster than the Bendix drive's operating speed (a few hundred rpm I believe) the flywheel will "grind" against the slower spinning Bendix gear when the gear tries to engage it. Hence, a major grinding of the gears until the key switch is released from the Start position. Or sometime the gear will engage and the Bendix will spin on it's sprag clutch which will sounds like a over-running worn-out bearing. Replaced many a starter with a ground down Bendix gear due to owners who thought the engine, which was running very quietly, was not running, when in fact it was. Some flywheels have ring gears that are more vulnerable to wear than the Bendix drive, resulting in a very expensive flywheel or ring gear replacement as well.
This action frees up stuck carbon brushes which have become too short to reach the commutator and carry the full current needed to run the motor. My uncle used to rebuild starters and generators in a shop in Colorado Springs. I would spend my Saturdays cleaning carbon dust out of housings. Learned a lot working there.
What 2 do if u have constant starting problems that come and go? starts good 4 a week or 6mos and all of sudden nothing no sound , and then bang with hammer and then good again maybe this time for 2mos.
@@richb6872 I guess the windings of the pull in coil has a very high resistance that is why the electricity ,if not all then most of it, will prefer to pass through the other wire. Electricity will always prefer to go through the path with least resistance.
Do you often use planetary gears for start motors that are produced recently? What is the difference between the two methods? (Benefits and Disadvantages)
1:53 Don't you mean that because the pinion gear is small in relation to the flywheel the pinion gear must rotate fast but can have relatively little torque? AFAIK that's the normal way these "transmissions" work. Just think of the bicycle as an example: - high gear means big cog turns smaller cog (via chain) and needs high torque to get up to speed. - low gear means small/same-sized cog turns same/bigger-sized cog (via chain) and needs little torque but high RPM to get up to speed.

The motor only draws what it needs and return voltage is always a zero sum.

Very nice. The assembly that moves the pinion into place is called a Bendix.
It is called either driver or bendix. Both are correct.
Amazing teaching I'm okay to explain how a Starter motor works

Both ends become 12V, so there is no where for the power to flow. If one end is 12V and the other is 0V, then it can flow.
