Please watch the Following video for Starting System Wiring Diagram Analysis: kzfaq.info/get/bejne/r5OApK9iy53cm5c.html

This is an excellent excellent and very clear explanation

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

Very good. Just what I needed

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

very useful video

آقا دمت گرم عالی بود. 👍

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

Thank you sir

Perfect tutorials, thanks

Excellent, thanks for this video

good

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

Thanks for the video

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?

Thanks

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.

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
