One of the best explanation on auto engine starter, very good video, but not many people know the value of this video.

[@AutomotiveDiagnosis]

Hi my friend. Thanks a lot for your kind comment 👍👍

[@Razz-es9qw]

Great Video. I work for a global diesel engine manufacturer and I see more techs miss diagnose starter issues, because basic steps are missed and not knowing how the starter actually works. Thank you for breaking down how the solenoid coils works using a meter and schematic. Make more videos, please.

Very good. Just what I needed

[@AutomotiveDiagnosis]

Glad to hear that

[@ShakirAuto067]

Good bro

[@mynameismud5139]

Very informative, thank you for the easy to interpret video I'm going to go see what's up with my starter now =) I'll be back by the channel to learn more

[@AutomotiveDiagnosis]

I’m glad you found it helpful! 🙏

Love you men for sharing your knowledge with us , thank you so much.

Thanks for watching 👍👍

Thanks. Massive help. Figured out my new solenoid had the main terminals reversed with your guide to resistance.

[@AutomotiveDiagnosis]

Glad it helped.

[@abderrahimmark]

You explain everything with extreme details. Thank you. Could you please make some video about diesels?

[@AutomotiveDiagnosis]

Hi my friend, I’m glad you liked the video. We have some videos for diesel on the channel, but I will try to make more. 🙏

[@peterballentine76]

This is an excellent excellent and very clear explanation

Excellent. Most other videos about starter solenoids here, don't go into the detail about the second coil.

Thanks

Perfect tutorials, thanks

I've found that many starter solenoids don't have an M post to isolate the pull-in coil. Do all starter solenoids have a pull-in coil, or in smaller starters do they simplify coil wiring by deleting the pull-in coil? Often the OEM dealers manual doesn't have enough detail to tell.

[@AutomotiveDiagnosis]

Hi my friend. Yes, most of the time information provided in the dealership manual is not enough, but based on what I have seen so far, pull-in coil is used in all of them. Also M terminal is needed to, because it must carry the high current to the starter armature too.

@@AutomotiveDiagnosis hello, please make us a video about the start and stop button how to check the wiring diagram of this system and how does it work

[@AutomotiveDiagnosis]

@@amarabdelli487 Sure my friend. I’ll put it on the top of my list.

Well done bro, my concept cleared. #mechatronicssolutionschannel

[@Martinuzm4]

Hi i done the last test you did however the pinion could not go up. Before then i did a test in which the pinion did spin up but could not hold up enough but spinning. Does that conclude to faulty solenoid?

[@mohamedelhusseny338]

If the resistance is between 37 ohms and 40 ohms in a Nissan Sunny N17 and if you use a buzzer with an ohmmeter between the can high or can low and ground, it will make a buzzer sound, and if you reverse the leads of the ohmmeter, the buzzer will not make a sound. What is the reason? Thank you 😊❤

[@Medkoroma]

Thank you sir

Good video.But I dare to add some starter selenoid have external R pin terminal suposedly it was used to bypass voltage to points ignition with an diode or alternator field or some other device,suposedly if you use the R terminal the pinion gear stay on the flywheel or odd polarity swap acures who isnt good for baterry or alternator ,another thing I want to add +12-12= 0v so that extra wire is actuali an compensation wire for that porpuse Im not shure about polarity just trust my about that it has to do with induction and colideing poles any way they are rated at around 24v so if you like 1 input to 1 out put dc converter cirquet part ,lot other devices depent on the + voltage and the negative voltage. For exampel delco 10-12si series alternators use reference voltage baterry negative to determine when to charge when tge cutt in fueld current will take place at what rpm range so it used higher negative some fractional lowr voltage positive from field or dash who are around 9-10v and it becomes partiali ac and some voltage is devided true diode trio then you get back flat line dc positive and negative true the bridge rectifier in %\% ratio difference + and - of corse the volts /apms ratio also is effected thats why those 2 wires are important not only for activating the starter motor but for all other devices in the car what depends on voltage potentials . Just add 1 ceramic capacitor or resistor or some wiard electrolitic capacitor instantli the cutt in current to the alternator field will change instantli even the starter motir will behave differentli as well the baterry volts/amps ratio will change . So hoppe this makes sence .Expeciali magnet type starter motirs are complexs they have lot in common with old compound dc motors and metadyne transforners so they are variabel devices with variabel out puts.Do not hit magnet starter ,do not heat ferrite magnets ,do not misplace pole peaces the end result will by same like with those old pulley driven dc generators they might change out put to the main brushes insted positive and negative it might by this - + or + + or - - ,as an out put voltage polarity .Just my way pointing out some things here.Nothing ells .Weak spots are also metalic springs,worn brushes ,commitator shorts and the actual brush holder and rear cover might suffer arcing welding the metal becomes blue so less metal compared to carbon so it will not conduct to ground .So you see guys magnet starter motors are lot interesting.Any way just wanted peopel to know if they get in trobbel so they know where to look for.

I replaced my solenoid and and relay and used aux. start switch for power to small terminal and still have intermittent start. It appears the pull-in coil is not getting sufficient ground. If the motor supplies the ground for the pull-in coil through the brushes does that show my starter motor is the problem?

[@adab4586]

Thank you for your video But I have a question please , how does you measure the resistance of pull in and hold in coils and get the right value if they are connected with parallel , you have to seperate them to get the right value for each of them because the two coil have the same start point and end point in reset status ??? Thank you again

[@AutomotiveDiagnosis]

Hi there, thanks for watching the video. They are not connected to each other from both ends, but only one end.

[@adab4586]

How is that ? Could you please draw a sketch for the ends for both coils and upload on the comments ?

[@AutomotiveDiagnosis]

Have you checked the starter relay?

[@djentlover]

I get 4000 ohms from starter solenoid to ground. What could be the cause of this?

[@djentlover]

@@bernardocisneros4402 The coil was burned so the continuity was gone. I bought a new starter and now the car starts again without problems.
