This video shares a great disassembly of the start solenoid, along with a vocal description of how it works. I recommend this video to learn and understand this mechanical part. Have a great day.

Thanks for sharing. It now makes more sense for me. Cheers

Question, I just finished up a repair on a 70-80s wood chipper I found a few issues. 1 the resistor wire from the ignition switch to the coil was melted and getting very warm every time the ignition is switched on. Also I noticed from the ignition coil pos. terminal there is a second wire running to the “I” terminal on the 4 post starter solenoid. On your solenoid schematic you show the “I” terminal is connected directly the the starter terminal. When I watch you take the solenoid apart it appears the “l” terminal is actually connected directly to the contact plate. That way when the ignition switch is turned to the run position the power wire from the coil to the “I” terminal will not be shorted to the starter motor. Can anybody understand what I mean by this? The way I see it the “I” terminal should be open until the starter solenoid is activated then is should be energized.

Curious why you didn't hook it up to power while it was open to show how it actually worked. Enjoyed the video.

Can you make a video related to how 3 terminal solenoid works, and wiring?

My 1951 Ford F1 has one and I'm trying to wiring without burn the truck down lol.

Thank you.

I think I have a solenoid issue that is not grounding. I went from a 3 pole to 4 pole solenoid on the boat and I can start it up but it does not allow the starter to disengage and actually keeps cranking the engine when ignition switch is off. Am I missing a way to ground it that is obvious?

[hueroski]

hpw many amps does the solenoid pull to activate and hold the plunger

[jerrym]

but what i want to know is how come i can only get the engine to torn over if i have to go straight from i Terminal) and s (terminal) straight to the battery and and will not do anything with the key. and i get no spark

[michaeldemers]

Is I ever connected to the ground? I have an old tractor that was doing nothing and now it is turning over at least but I have no spark. Is my coil bad? I am confused.

[nicelez]

Is the Relay directional... Meaning, does it matter which post the main starter or battery power is connected to? Thanks

[marcoalvarez]

That was so great explanation thank you so much even though I knew how it works I never actually open one

What about SR type starter selenoid?
I do not have points I have 4 pin gm ignition module with e core type ignition coil .
So I have problem there me fuse pops .
I did try to use diode flip wires swap pins on e core coil nothing just fuse pops.
So some thing is polarity sensitive .
So how can I bypass this problems???
I have multipel selenoids wuld useing 2 of those selenoids do the trick ?

[lloydrosenthal]

On my solenoid it does not use the chassis ground. It uses ground from one of the small poles.

[frankdavidson]

the mounting holes are not part of the circuit on the 4 pole they are part of it on 3 pole

[CharlieStephens-xb]

How about forgetting how you unhooked it and hooking it back up

[lloydrosenthal]

There is no continuity between the chassis and the S pole.

You asked for comments. I would love to get something educational from your video. But I cannot glean anything from it. You might ask why? Because every time I am ready to look closely and connect the visual with your words, you run the video on such an extreme fast forward that no one's eyes can take it in. It's like trying to focus on a weed whacker string while it is running full speed!
PLEASE! Go back and re-edit your video and let us actually SEE.
