Don’t do that an German cars you’ll fry your ecu or dme and you have to pay up 5k for a new one

I have 2017 same thing. I said balin wire the same time you did!👍

Good explanation brother, straight to the point thank you

My secondary is at 130 and primary is at 120. What could it be? Can I dtill drive it?

If you can get the vehicle running disconnect your jumper cables and then disconnect the negative terminal of the battery and if the car dies then you have a bad alternator

True. But I don’t want my car to die on me in the middle of July heat with my daughters. I should have gotten my alternator checked, autozone, advance, and O’Rileys will do it on the vehicle. A week later after I first noticed low voltage on a year old battery I ignored it when it went back to normal. Bringing my daughter home from my parents, halfway back I got a “check charging system” alarm I had never seen, and the car was dying from that moment on and only took 15 minutes to die. Only 2 miles from home when the car completely died. I believe the alternator failed in a way that sent unregulated power to the battery and fried it as well. Because when both were tested at the above mentioned the alternator tested bad and the battery was not even reading.

Everything looks good on mine I hit a root and ever since it won’t move. Any suggestions?

Yeah do that to a newer car you risk frying the computer in your car only on old cars that works and no problems will happen and trust me the price to replace that computer will hurt ya

usually it's a vacuum leak, causing lean conditions. my customer is experiencing loss of power and stumbling under load. about to open up a 2000 with only 70k on it. hopefully it's worth the 10+hrs I'm billing for it.

I don'tappreciate your obscene language!

genial

How did u tighten belt ?

thats awesome

Al ways check your fuses. Before remove alternator. ( Connection s fuses and take the alternator to test. Before you buy another one ) Same whit the battery

I could be wrong, but I remember when cars had generators, and would run without a battery in the car off of the generator. I still have a car that I have owned for decades -it has a generator - a 1958 mga English car I was 16 when I got this car - 1968- I was working after school- weekends- summers in the local service station on cars, I don’t know if it’s true, but I remember hearing that if you run a car with an alternator and you disconnect the battery while the car is running, that will damage the alternator .. Maybe alternators are different, maybe that is not true - but I do remember being cautioned not to disconnect the battery of a car with an alternator while the car is running…

Will that happen if your battery is bad?

Like so many other, I couldn't have gotten this switch back together without this video.

I seemed to have difficulty installing the spring switch too... it's really damn😂

I realize this vid is old but for any who wonder. When reinstalling the switch components, after assembly the problem is how to keep all together to put together the seal and it’s cup. 1. After switch assembly, use visegrip and hold the bottom plate at its pivot point. 2. Use light gage, like 30 gage, tie wire and wrap the plate around and over the motor input connections, twist the tie wire to hold the plate from springing out of its position. 3. Install the switch into its position. 4. Screw switch and all its components as they were originally 5. Once screwed together, clip tie wire and pull it out. 6. Install completed switch to original position, rewire and test.

only for petrol not diesel

Great tutorial! Saved my bacon! Thanks

Thanks a million. I couldn't figure out how it went back together. You made my day better.

This is horrible man. You keep removing the positive cable and reattaching. You are so lucky you didn’t get a power surge… you always remove the negative cable first

I always just put a screw driver on the back of the alternator while it’s running and if it magnets to the back it’s charging

Don’t ever disconnect batteries while vihicle is running. Battery your alternator can spike up damaging many critical and passive electronics that will send you on goose chase for long long frustrating time

Better yet, get a cheap multimeter (Harbor Freight has one for about $7) and test the battery while the car is running. Lots of KZbin videos on how to do this, it's very simple, anyone can do it.

thanks brother. my compressor wouldn't start after I foolishly unplugged and replugged the power without turning off the switch and so I decided to have a look inside this "box" and of course, things went flying everywhere and I had no idea how to put it back together. I eventually learned what this box is called, and now with your video I reassembled this pressure switch. it looked quite frustrating, but I rook my time and all went well. I did use some zip ties to hold the parts together because I knew it would go flying apart for me if I didn't. anyway, during this project I discovered the reset button as well, which probably would've fixed my initial problem. I've also changed the oil and evacuated the little bit of water that was inside my compressor. I also reset the cut-in and cut-out pressures, and now the whole thing is working better that it did before. I'm so happy. I inherited this compressor from my late father and it comes in so handy. I would've hated to have had to buy a new one. So thanks again for your time. Also, sounded like James was working on his own project in the background. :)

Good advice

what would i do for a 327 chevelle motor?

Those old school jumper cables are some bad mofo can really handle a lot of amperage wished I could find a good set like that all I seem to get is weak flimsy trash. Those jumper cables will bite into the lead and get a good connection even thru corrosion

If you disconnect the battery, and your car still runs, your battery is bad??? Wrong!!! That only means your alternator is still good. Has nothing to do with battery.

Do this ok,to check our alternator, disconnect your battery neg. Terminal your engine should stay running , if it shuts down ,your alternator.isnt putting out the 14v. Or 12, whatever,, I had this problem , also,,,,,if your cars Wipers start slowing down or the instrument panel dims , or you have an invertor check that,if it shows lower that 14.1 your alternator is bad ..

2016 gmc sierra and in the service manual it say DO NOT under any circumstances do that ! It will fry stuff

I have a 2012 Hyundai sante lights are blinking us it a bad alternator or starter need advice

Currently on the side of the road, re did my connections and waiting for my jump to get here, hope it works

My sister's alternator went bad on the road. She was stranded.

Would running a higher octane fuel improve the efficiency of the alternator creating energy therefore maintaining charge on the battery more efficient and reducing wear and tear which would likely increase the systems longevity? Or is that more along the lines of trying to make a dumb question sound smarter dashed with a meager attempt of humor in an otherwise all too real situation that I find myself in right now!? Just whatever you do, don’t open your hood, get out and lock the doors because you’re broke down on the side of the road and you’re gonna take your battery to charge whilst visiting the local auto store to procure a new charging device or more commonly known as der alternatorenstein or “alternator”, so you remove the battery and close the hood only to then realize you have electric door locks and in order to open the hood you have to gain entry into the vehicle which has been locked and the battery removed so you think that’s ok I’ll just resort to action necessary to accomplish such tasks and do it the old fashioned way like our forefathers did and put the key in the lock on the actual door and viola … the key won’t actuate the mechanism that is dependent on electricity to lock and unlock the door and now you can’t access the hood release to… But don’t fret, I didn’t totally close the hood and can still open it by the release under the hood as normal. Whew. Ok enough if this, I think I’ve spent adequate time to full recharge the battery so off to the Zone…AutoZone. I’ll make sure ti do a follow up, for those interested, on some other random comment area so follow up isn’t necessarily guaranteed but didn’t want to leave anybody hanging because we all know how much that sucks. ✌🏻

Not good to do this with most cars. Dont disconnect your batrery lol maybe for an older vehicle not so bad but dont do this yall! There are other simple ways to tell

I also had the spring explosion........no way to know how to put it back together. Thank you. I could not get the contraption to stay together for assembly. used a zip tie to hold it all together.......and had success. thanks again. i would say you have a patient delivery. so many info u tubes are done too quickly. You are the man!

hi there.thanks so much for your time doing this,james sounds like a buding technition coming up ,,make the the most of your time with him my son is now 51 ,time flys buy so fast,regards TW..Canada,s west coast

That's nice to know thank you

Brother you are a God send. Thank you very much!

DISCONNECT CABLES??? AS IN BOTH CABLES?? 🤔

Only on older vehicles.

Seems easy enough! Thank you!

Great video, thank you! And James was great to listen to!

I've never swabbed with 1/4 line always used 9/16

ALSO you should also always keep clean terminals and posts wire brushes and wire pipe cleaners are simplest but they also make that wire tool thing (different versions) and battery connection spray. Help jump a lady's car one time who said that she kept having the same problem and sure enough as soon as I tried to attach the cable the terminal lifted off the post and it was clear that she just had a really loose cable so yeah start with the simple stuff first obviously

All day long that means you have a bad Alternator

This video saved my ass lol thank you brotha
