Very nice job fella. Now I have a list of probable causes.

Awesome video! 👍🏽

I bought a 2014 passat TDI not even a year ago and i’ve had to replace the alternator twice. It just went out again and i’m getting really frustrated because nobody can figure out what’s wrong. After watching this, i have a fleeting suspicion that diesel might be getting into the alternator and trashing it. There is a fuel leak somewhere and it creates a mist of unburned fuel in the engine bay. I’ll be getting that fixed along with a new alt and hoping for the best.

Great content 👌

I've been popping alternators on my boat. The start battery is new but the house battery is 4 years old. The Atem charger sends a10 amp charge over to the house battery after the start batt is full. If the house battery has a bad cell/short, would that kill the alternator ??

I got 2006 Buick 1 .5 year ago since then 3 times alternator stop working... yesterday I stopped working out of the blue... definitely something is wrong with the wire system 😢

Thank you for that, concise and easy to understand. Try as I might, I cannot find anything definitive about maximum temperature that a stock alternator can safely run at, no OEM numbers or even consistent "expert" opinion. Regarding your item # 4 about extra loads; I am drawing 20-40 amps extra (depending on how I set it) from my 160A alternator to charge my RV battery when driving. Running normally with all usual loads (headlamps, fan, wipers, radio etc) max draw is up to 65A or so. So it stays well under it's rated capacity even when charging the extra battery. My intent is to measure temperature with and without this extra load. Is there a "safe" maximum temperature that should be adhered to?

My new alternator stops charging the new battery when I run my AC. Any hint about what causes this ?

So I’ve been having issues with mine I’ve changed this being my 3 one but this time I bought a new one instead of a rebuilt but I have noticed that I get a wine sound over the speakers then the alternator goes out and the wine goes away? Any suggestions?

Hi i have a L300 mitsu . And it keep burning tha main altinator fuse when i rev the van? I brought the alt. To a specialist rebuild it .i thought it was the regulator but it is doing the same thing . Help plzzzzzz

Town and Country turned still can't get it to charge change battery and alternator twice and alternator just won't charge. I installed voltage regulator kit and still not charging. I can't believe two new alternators could be bad. I can't figure this one out!

Melted my alternator doing a race at the drag strip. Windings completely melted. I don’t know what it could’ve been, maybe track debris, oil from the oil cooler, or maybe the engine just pulled so much current it fried it.

My problem with my alternator malfunction was steering wheel fluid getting in my alternator. Once I got that fixed, my car is running very well.

Thanks for the video, great info. Trying to figure out why my 2011 Edge keeps burning the alternator, since last Friday have changed 4 alternators, today is Monday and still haven't figured out what is wrong. After install everything looks good, no dash massage, once the car is moved the dash light appears and burns the alternator.😭any suggestions will be appreciated ✌️

I don't think I wNt to ask a question which would be ignored

Thanks very much for your video, it is helpful to me. Right now, I am trying to figure out why the factory-rebuilt Bosch 140A alternator I just installed in my 89 BMW is charging fine (14.2 A) at idle but once the engine warms up it drops to around 12V. Car starts right up, correct battery 1 year old, no additional electronics, engine to chassis ground strap new, You obviously know a lot about these things. Any suggestions for me to pursue?

Mice are gremlins to!

My new alternator burn after 20mins

I keep putting new alternators keeps smoking right when I put them in. Any reason for this?

If it fails within the first hour
