Great video mine looked exactly like yours and the slip rings were clean as a whistle but it doesn’t matter is they do t make contact you save me some money I salute you sir and now follow.
Hi there, I just did an inspection on my Alternator on my 2008 f250, and looking at your unit tells me that that unit has been working to hard, which is probably why the negative brush is burned out probably due to bad weak grounding points along with a weak battery. I'd do a all point inspection of the charging system - all cables for corrosion, and do a battery analysis of the internal resistance, and try and clean up any points grounding the alternator to the system. WOW you can even see where a hole has burned into the slip ring...
Agreed. Brushes are normally the cause of failure and often you can buy loose brushes and solder them in.Bearing are always close to worn out at high mileage so replace them. Also, the free running pulley's often seize up and need replacing. They are so easy and cheap to fix properly there's no reason to skimp on repairing them.
I have a 96 E350 RV. Every off season i store it with a solar charger on engine battery. Amost every spring Alt. Only puts out around 8 to 10 volts. Had original rebuilt twice and bought a rebuilt from Advance. Just fired it up and only showing 8 to 10 volts again. Any ideas?
Does the voltage climb when you rev the engine? You need to make sure the battery is at above 12v volts or higher before you start it and see if that makes a difference.
Are the toothbrushes supposed to be that much difference in size naturally? I know you said something may have gotten in there but would that cause it to be that much shorter? I have a 2012 focus titanium hatchback that has a new battery in it and it’s been in there for a couple months and now the car keeps dying and won’t start so I’m assuming it’s the alternator. I’d love to try this trick if I can access the rear of it if not I would have to pull it off completely and at that point I feel so I should just put a new alternator on.

Thank you very much for helping ordinary DIYers. 👏🏼
Great video, friend - and a great, simple explanation on WHY these things crap out on Ford alternators.

Thanks for taking the time to instruct.
The nice thing about Ford alternators is the bearing will give out before most other parts. Totally totally unlike Ford's main competitors.
😂😂😂😂😂😂😂 Yeah if I’m taking an alternator out of a POS domestic truck it’s getting a new one!
If I replace the bearings I’m finding a collet to run some Reds skateboard wheel bearings lol

Yep. Looks like the same as my issue. I just wish you would have zoomed in on the slip rings.
A lot of the time, cleaning up the rings with emery paper does the job. Shiny and smooth, that''s all you need.
he only has one ring this thing is toast
Install new slip rings, they only cost around $10, plus brushes at about $8 ...
Mine had a couple cold solder joints on the rectifier. re-soldered and good as new.
Im going to try this on my 95 ford. I'll update once its put back together.
This could be a game changer for me.. I'll take a look at mine and see if this is a thing! Thank you
Every store want 250 or so for replacement so will attempt to fix if possable. Thanks
Thank you im going to give it a try, on my 1991 ford escort. 1.9. I'll let you know how it tested
How did it go? 95 escort asking 😂
@@n3alsnail299 Same here '92
Brushes aren’t the problem. It’s the slip ring. Those brushes would last another two years with a new slip.
If only it were easy to replace the slip rings. Not impossible but usually not worth the effort.
Thank you very much
Good information!
Take the alternator off of the vehicle for testing. Many times it will test good when on the vehicle
thank you
Nice.
Great description
Good video

Toothbrushes?
What happens to them the other 10% of the time? 🤔
The regulator goes bad 8 percent of the time, the windings open 1 percent of the time, and the bearings fail 1 percent of the time. :)

Thanks ✌️
Will that fix the whine replacing that part?
It's possible.
Where do get parts?
slip ring is gone. this unit is trash.
Just buy a new alternator
If you think Paying up to 200 $ for a new alternator is a good idia you shouldn't be here Mr.$$$
