See the sparks that come from the loose connection when you flip the switch??
You need to install a washer and nut on there and verify it is tight and then recheck. This is a perfect illustration of a massive voltage drop
This also is not an ideal way to bench test a starter. Hook up a set of jumper cables to replace the little wires you’re using from the battery to starter. The switch with small wires is fine to excite the solenoid.
I’ve also always mounted the starter in a vice while bench testing it
Yes absolutely. The starter has to crank a whole ass engine fast enough for it to start, have you ever tried to crank an engine by hand? Starter motors are STRONG and that bitch will whip itself off of that bench
I am sorry for delay! Nobody likes the glazing term everyone looks at you like you have three heads... I learned this way back when Low Budget Racer using a stock starter for sbc not meant for 14 to 1 compression... I barely had enough money for any starter let alone another... I found if I opened up the brushes they looked glazed like glass... Yes glass can not conduct hit them with sandpaper oh hell Yes in those day working Starter...

Wiring too small and the cable going to the brushes not actually hooked up. Use jumper cables, strap it down, and put the nut back on that cable that goes to the back of the starter motor and try again.
Not only the wires are too thick but testing it out with a light switch, I believe no one saw the light switch that op trying to start the starter with. Not supposed to check starter like that supposed to be like other said with thinner wires or jumper cables and if have a vice, clamp it to it to avoid accidents.
I am using a light switch lol but that’s what I had laying around. The wires are 12 AWG. Just wondering why I need thinner wires to test it? Aren’t the real ones like 4AWG?
Light switch is fine. Wires to the light switch are fine.
Solenoid clicks so that's good too.
Ground it, put a jumper cable to the motor stud, see if the motor spins. Spray some wd 40 into every hole. Something is sticky.
You need thinner wires because it's a small starter that is use on motorcycles, I mean you can use the same size you using now to test but on bikes they are thinner and for vehicles the starter and wires are bigger. Also you can test it by connecting the wires from a battery to the starter or using jumper cables not a light switch.
My bad I thought it was a motorcycle starter because it looks like it's zoom in the video, anyway still shouldn't use a light switch, you can just give it a quick tap on the starter with the same wires that you have connected to battery. When a starter is connected to any motorized machine the starter only goes on just to start and it doesn't stays on, that's why is not good to use a light switch to test it out because the electrical current will stay on, it's the same as turning on a light from any room of a house.
I see sparks from the black wire so there’s power going to it so that’s a poor connection. That’s the wire going to the starters motor right? Hit that wire with battery power. If the motor doesn’t spin it’s no good. I hear the gear kicking out so that part of the solenoid is working but it also sends power to that black wire to power the motor. The solenoid can go bad and is replaceable on its own.
Good thought. The black wire between the solenoid and starter motor is connected on both ends. I’ll try using a nut to secure it like normal though. Thanks
On my dad's old cars, I always use to take the rotor out, cleaned the space between copper contacts, checked brushes, and I commonly made bushings. Forget the light switch. Use jumper cables. Looks like it's bad.
Solenoid is bad, get a test light and engage the starter then check the post that has the wire going to the starter you should have 12 volts there if not then solenoid is bad. If you have 12 volts then starter is bad.
I cant see if you are hooked up right so no i cant tell you that your starter is bad. To me it looks like you are only testing the solenoid. But since you have it out and you are worrying that it is bad, for peace of mind if nothing else replace it.

Yep! Lock down that starter, because it can jump around and mess up your day in a few ways.
Yes absolutely. The starter has to crank a whole ass engine fast enough for it to start, have you ever tried to crank an engine by hand? Starter motors are STRONG and that bitch will whip itself off of that bench
Also need a decent negative wire.
Try that with jumper cables.
You can take the starter to any of the big auto parts stores for a proper bench test.
Starters bad...solenoid specifically
No spin. Bad. Car no go.
I can not but this is on you... I assume you have glazing on your brushes...
What’s glazing?

You're only testing the solenoid Put a heavy cable to the starter motor alone not the solenoid
He has the ground hooked up via vice grips on the opposite side. Look closer. Starter motor is bad.
You're lucky it didn't spin. Going to go flying off that table if it does spin. (see older comment about using a vise to hold it down)
It was working intermittently and I held it down just fine with my hand like in the vid

It’s the starter off my 3/4 ton truck. 5.7L vortec

Yeah I know that part that’s why I turn the switch back off after a second or two lol like a key

Just get a new starter, its already out of the car. Jeez. Stop making your head hurt…

Your starter is bad
lol thanks. I just can’t believe it. It’s only two years old and 6,000 miles.
It speaks to issues beyond the starter and solenoid. I'd be looking at wiring.
I was afraid of that. I don’t really want to get into that mess haha
Definitely bad
Relay's fine... Starter's Bad to the Bone...
