Episode No.127 - The Starter Motor

THE complete guide to starter motors. Stripped down and fully explained, including a detailed explanation of starter solenoids, planetary gears and sprag clutches. This video is detailed and easy to understand.
This Mitsubishi starter motor is taken from a Mazda MX5 Miata.
Check out my 20-hour Series on automotive engineering at www.howacarworks.com/video-co...
CORRECTION: From Graham at Wood Auto:
[...] There is pretty big mistake around 8:30 regarding the “400A” sticker on the starter motor. This “400A” is part of the Mazda part number “BPD418400A” not an indicator of its amperage. The underlying starter motor is a Mitsubishi M0T80081 starter and its only rated at 1.0kW not 4.8kW! Below is a link to photos of the OE starter (this has the Mitsubishi sticker on it not the Mazda sticker):

You’ll see the side photo shows the rating of the starter.
You’d only really see 4.8kW starter motors on commercial vehicles. To my knowledge starter motors never show an amperage rating, they’d always show a kilowatt rating. Only alternators would show an amperage.

I can't put into words how phenomenally informative your videos are. This was carefully researched, scripted, and presented with incredible visual aids. Your channel has single handedly changed the game. Keep up the incredible work

[@dinoflame9696]

visual aids lol

[@sizzlean9459]

What game are you referring to that this channel changed? As far back as I can remember all the dope pushers have always given you the first hit for free and you got that, now if you want more your ass is gonna pay. You didn't really think you were going to get an ASE Patch on your shoulder for free from youtube did you? In the next step they'll get all your information before they let you know it costs money for the rest. Personally I despise the sneaky shit and it just does not matter how awesome the course is, if they don't have the balls to let you know up front their is a price then they don't deserve my money. Besides 99.9% of youtubes audience could watch the whole course 3 times each and it wouldn't help you one bit if you took the initiative to try to repair the car yourself. If you need these courses then you have zero skills and if you have zero skills or experience then you didn't notice he didn't give you any knowledge or tips on trouble shooting it or removing it and putting it back in because it is hilarious when a rookie meets the starter and it's grease and lovely location in real life, that is why mechanics are rapists,,,,,because they always have fresh new meat walk in their doors and most people are too dumb to know when they are being screwed anyways. They have not changed the game, they're still playing the sneaky ass snake as always. If they had put " for 25 dollars you can learn everything you need to know about cars" I would gladly give them the money just to have it in my collection for reference even though none of it will help you fix a car if you're a rookie and much of the data was wrong rookie Sizzlean

I bought his whole 20+ hrs course and I can wholeheartedly recommend it. My god, I've never seen anyone explaining things better, more thoroughly and at times funnier than him. The cost-value ratio is unbelievable, this course should cost 10 or 100 times more and it would still be worth it. It's not only about cars, he also explaining fundamentals in electronics (e.g. how a battery works, what voltage and current and power is to understand the car's electronics, etc.). I really love it, it's incredible man! Note that previously I had no clue about cars or their inner workings whatsoever, but after watching the first few hours of the course I'm seriously thinking about buying a 500 euro car and tearing it to pieces to apply the knowledge hands-on. Alex, let me tell you this: whatever course you might provide in future (maybe on motorcycles or anything else also not related to vehicles), I'll buy it for sure! You're an amazing teacher, that's a gift. Love it :-)

As an Auto electrician (in a previous life), you have nailed this. Well done ! I can tell a great effort has been invested to make this video.
