What's inside a starter solenoid and what it does January 15, 2018

[@irenemackenzie3232]

No music, no jazzy intro just the info I needed - perfect!!

[@blairwise3339]

Do not apologise for your presentation. It was awesome and I just learned everything I needed to know. Thank you very much.

[@57bagre]

Glad it was helpful!

[@dalegribble60]

I had a "no start" click from time to time. This fixed it but like your jacket don't fix that. That jacket's got more miles on it than my '54 Pontiac and is a CLASSIC! Good job.

[@steveliedel]

Your videos are “Kick Ass” do not change a thing!

[@johnhansen7922]

Still relevant. Thanks for taking the time to show us this. As for how you communicate, perfect. God bless.

[@andrewphillips9798]

Great video Gordon. It really assisted me in doing my own. Also, well done for not impaling yourself on the bolt sticking out from your bench right next to your crown jewels. I'm sure its there for a reason, but you might want to find a different location to do your work 😁

[@iainbarker4935]

What a pleasure to watch a skilled professional at work. Wish I could like this twice!

[@TheDisorderly1]

No need to apologize for your presentation Gordon. You did a great job of providing the necessary information that a person would need to get their vehicle running on their own when the parts stores are closed.

[@57bagre]

Thank you sir.

[@damianbutterworth2434]

There are 2 coils in the solenoid. A pull in and hold in coil. Both coils activate when you turn the key then when the starter contacts make a contact the pull in coil is turned off and just the hold in coil works. It saves the solenoid windings overheating.

[@michaelcaplan3532]

Your videos are super great. Thank you for your patience in filming and narrating your videos.

[@57bagre]

Thanks Mike.

[@brandonmalik3910]

You all prolly dont give a damn but does anybody know of a tool to get back into an instagram account? I stupidly lost the account password. I love any tricks you can give me

[@merrickorion1954]

@Brandon Malik instablaster ;)

[@anthonypirrello2473]

You do just fine in presenting your videos. I like your patience in doing the sometime tedious work plus I like your looking ahead when assembling and disassembling parts.

[@57bagre]

Thank you Anthony.

[@robrod2962]

Great show and tell. Thanks, and nothing at all wrong with your presentation.

[@alexday7474]

Great video and very helpful. Thank you!

[@Aaron-ro2yz]

Thank you for taking your time to show us how this works

[@57bagre]

Thanks for watching. I should be doing a starter and an alternator soon, watch for those videos to come.

[@edwinalvarez4373]

Thank you my friend. You are a good teacher

[@stanpatterson5033]

Another "first"... first time I've seem a starter solenoid opened up. I've known the principal of what they do and how they work, but first time I've been able to see it from the inside. Very informative. You narration/presentation is fine. We aren't all born to be public speakers, but knowing that you are trying to think, run both hands, and spew out your lines all together at the same time, I'd say you're doing quite well. Thanks for this tear-down/demonstration/reassembly. Hopefully this solenoid will serve you for years to come, should you ever put it back into service.

[@57bagre]

Thank you Stan.

[@srdoberman]

As always Superb! Thank you brother. Happy Trails.

[@owensdaniels6244]

you are awesome!!! thankyou! for taking time to teach us about this starter solenoid youre a great!! teacher! thanks! again!

[@diamondcutter8535]

Thanks! Just what I was looking for, JD4045T.

[@richarddoire2872]

Greatly appreciated Gordon.

[@57bagre]

Thanks Richard.

[@geraldwayne6261]

Great video! On the plunger, if you ever have one that is all pitted, you can take it apart and flip the disc over! flip it and hit it with the wire wheel and you're good to go!

[@cedarwest37]

I see your jacket... you must be a good man!!!

[@donf3739]

Very informative. Thanks for making this. That jacket looks sooooo comfortable. I have one like that too. :)

[@57bagre]

Thanks for commenting.

You say it great bro! Thx from Belgium, 😎🇧🇪i subscribed!

[@amiellabrador3505]

Thank you sir, you really did explained it well. I'm a student and currently learning my way up to this profession. This is a huge help.

[@57bagre]

Good luck in your studies. Thanks for watching.

[@TECHNICUSChannel]

Hello i tok dismantling many things for your sience

[@pauharpe8464]

Great video

[@hmayerv8]

Great video. One point I was hoping for some explanation. Most people explain the 2 large terminals indepth and how they're energised and what happens to the internal parts, the disc etc etc. But I can't seem to find explanation or info on what happens inside the S and R terminals inside the solenoid. Are they energised, where are they connected to inside, what happens internally when 12V cranking power is supplied? There has also been a lot of debate on the S and R. Some say forget about the R, some even say since it's a 12V bypass to the coil, and your starter doesn't have the R, then just connect to the S and it also delivers 12V cranking power. Looking forward to your advice. Thanks

[@57bagre]

Unless you have an old vehicle, tractor or machine with breaker points ignition you won't have any need for the "R" terminal, it is a resistor bypass to the ignition coil. The breakerless or solid state ignition that is on everything now since before the '80s doesn't use the resistor for the coil. On this video the other terminal is not a "R" it is a ground because this is a big truck solenoid and is wired a little different since it is a diesel.

[@stewartalbert3523]

A Resler And Gerald Wayne ,Old GM solenoids were made so flipping contact disc was easy . Later models were much more difficult . Good point on pull and hold coils , i dont remember a coil fail in solenoid . not an expert ,but thats what i remember. Kept my vehicles running for years , visiting salvage yards and trash cans .

[@57bagre]

Thanks for watching.

[@dc440-4]

Thanks for the info. I didn't know it pulled the plunger with electro magnet. I thought it pushed the plunger with a rod or something! Thanks I learned something from you. I cleaned mine up but it still don't work I think the electro magnet went out,it just make a noise but nothing happens. My starter is still good though.

[@57bagre]

Thanks for commenting.

[@philhugill8458]

My 2003 S-10/Blazer solenoid seems to stick periodically and nothing happens when I turn key to start. The thing I've done to get going is to hold key to start position and hold it there fore 30 seconds. I guess it heats the low amp cercuit enough to unstuck and the motor then briskly starts.

[@Jaeswindell]

Another great video! Love the new setup! Quick question, when you get a replacement starter do they not come with rebuilt/new solenoid?

[@Jaeswindell]

I spoke too soon, you answered my question at the end of the video. Thanks for sharing!

[@57bagre]

Thanks. Yes the starter comes with a solenoid but since I sometimes do the rebuild myself I like to keep the parts handy, sometimes the solenoid gets broken and the starter is still good. I just thought it would make a good video since I just did a starter repair.

[@darkfox77]

there is orange covered rubber covering a series of springs, and a simple nut. but how to transfer it to the side you cleaned up.

[@dv5486]

Great work sir! Thank you for another excellent video! I have a truck that drains batteries(when parked over the weekend). Would it be possible for me to put a starter solenoid in line on my battery cable and run the little wire to a remote toggle switch on the dash? Or would it burn up the solenoid to be energized for several days in a row while I'm working? I've considered a manual shut off switch, but cannot find a suitable location for it that is out of the weather and/or doesn't require removing panels to get into the battery box and/or requiring several feet of additional cabling.

[@57bagre]

Thanks for watching. To answer 1 question, you can buy a solenoid that can run continuously from a camper or R/V supply but I would never do that for your problem. I would 1st make sure all your batteries are in good shape, I have videos on that in my playlist of auto electric after you're sure they are good you need to find the source of battery drainage like leaving the power inverter turned on or a light on in the storage area under the bunk etc.

[@michaelday566]

GOOD JOB

[@aresler6085]

Mr. Robertson's excellent video omitted two items: First, there are two coils in the solenoid: a pull winding, and a hold winding. Both connect to the S terminal, but they have different grounds. The hold coil grounds to the case, so it is always grounded. The pull coil, however, grounds through the tab on the large terminal connecting to the starter windings. As odd as this sounds, it grounds through the windings of the starter itself. (The difference in resistance between the starter windings and the pull coil is such that when they are in series there is virtually no voltage drop across the starter windings, allowing the pull coil to see almost the full battery voltage.) In operation, when the S terminal receives battery voltage, both coils together move the starter drive into position, and then engage the starter relay at the end of the stroke. This shorts the pull coil ( both sides at battery voltage), leaving the hold coil to keep the starter drive in position, and the starter relay engaged. I have seen the hold coil fail: then as soon as the pull coil is shorted, the relay drops, re-enabling the pull coil, and repeating the cycle in a very noisy chatter. To Mr. Vest's question, I don't know if the hold coil alone will engage just the relay (assuming there is no starter drive being moved into engagement), without the help of the pull coil. Obviously, any parasitic drain in the truck's electrical system will provide some ground to the pull coil, helping the hold coil. I don't have a solenoid to experiment with: anyone? To anyone doing the experiment, I suggest holding the core about a quarter inch from the end of stroke, so the hold coil isn't moving the core the full stroke. Second, older spark ignition (not diesel) solenoids have a C terminal, which is also contacted by the copper disk in the relay, and which provides battery voltage to the ignition coil, bypassing the ignition ballast resister, and allowing the ignition to see the full available battery voltage, and not roughly half voltage, the other half being dropped across the ballast resistor. The ballast resister saves the points by lowering the voltage, but is a liability when the starter pulls down the battery voltage. This all became obsolete when electronic ignitions, which generally don't use ballast resisters, replaced points.

Great knowledge great thanks for sharing.

[@whiteface5055]

Hi. Good video. I have a Massey 285 tractor. I was having trouble starting it. Turn the key and one click. The starter turns over when I jump the two large lugs together. When I ark the battery lug on the solenoid with the starter terminal it just clicks. I checked all my cables and the lug to the copper bar to the starter was corroded. In the process of removing the nut, I broke the back off the solenoid. I will order a new one after Christmas. Would the solenoid have been defective in the first place. It sure is now. Any advice would be helpful. Merry Christmas to you. Thanks.

[@57bagre]

I think you do have a solenoid problem, if the solenoid is mounted separate from the starter then you don't need to order a special one from the dealer, you can just get a generic one like what was on the old ford cars. Here's a link to a video I did a few years ago. kzbin.info/www/bejne/fXLOl4ZopNugb7M

[@ragman0696]

Does the Bendix have to kick out for the 42 MT starter to spin?

[@57bagre]

Bendix is a brand name not a part name. But yes the solenoid will engage the starter drive and the starter at the same time.

[@rickray5884]

That a Boy Gordon!!!!!

[@tanglewood777]

i have classic car triumph stag and mine is just cliking and when I ark it out the starter just spins and doseant crank engine it mite crank it now and again I was wonder ing I put less amp battery on car would that cause it as its only started doing it when I put diff battery o it its got v 8 moter in car

[@57bagre]

maybe try it with jumper cables, if still no good change the starter or better, take the starter to a starter and alternator shop for them to check it out and fix it for you.

[@balsonnaoshekpam5680]

Thanks

[@57bagre]

Thanks for watching.

[@petemoss9693]

It must of been a little tedious having to align the small terminals bolts through the cap - how many times did you curse and throw the relay against the wall before you got it right ( ha ha ha )

[@57bagre]

Not hard at all, it may have looked that way because I have clumsy fingers. Thanks for watching.

[@darkfox77]

hey how about the bottom side, need to know this. to get my old girl going.

[@manfromthemist1958]

as irene says perfect, just the info required

[@williamzoom]

Pretty nice not being out in the driveway isn't it :)

[@57bagre]

It's nice to have my shop back. I couldn't work outside now anyway, you'll find out in a couple days when it gets over your way.

[@williamzoom]

I think its 29 here now:)

[@57bagre]

we have single digits tonight and tomorrow night, Thursday and a few days after we'll be a little above normal

[@tommythreetoes9524]

You can tell who the millennials are... four out of 201 votes dislike this video. Rotating that battery post the remained in the housing 180° (at 4:34) is an age-old trick to get life out of Your could-be-good starter. This is a step further and I very much thank Gordon for posting something that could save people time and money. Imagine, all You need is a solenoid. The part house won't have it till tomorrow morning, but You have a dinner & drinks date with Olivia Wilde, Jessica Alba and* Lynn Collins at the same table TONIGHT! In the time it took You to drive to the parts store to call around to all* local parts houses or drive to your favorite and get the sad news, You could have had it installed and working, washed Your hands, thrown on some English Leather Wind Drift and broom broom BROOOOM!

[@57bagre]
