I CAN REALLY LEARN SOMETHING FROM THIS GUY ! VERY INFORMATIVE !

Bro you have no idea, how much you are helping me. Thanks 🙏

Important: For those who don’t know. The Alternator “shroud or fan blade” SHOULD NOT MOVE!!! It should be secured to the pulley after tightening of the nut!

Excellent. Straight to the point. Your good.

You make it look so easy 😄👍

great video thanks for the time taken to make it.

Awesome video. This really helped me out. Safe travels.

going to do one tomorrow,,thanks for your video

Excellent Great explanation and quality Thanks brother

15:11 what do you call this long iron part that you are using for loosening and tightning the belt please?

You may want to invest in a universal puller. Yes, you won't need one much, but they are inexpensive enough to justify owning one so you don't have that hassle.

Nice video. Thats not a horrible voltage, standard automotive alt spec is 14.5 +/- 0.5, but for long term running it is a little high. Does that alternator use remote sense? If it does, perhaps that sense line has become disconnected somewhere. you could connect it to the B+ terminal, which would lower the voltage at the batteries…

Thank you for this video. the truck battery got down because the alternator was not charging. How long should take to charge the truck battery in full after I replaced the alternator?

@DIYSEMI

Жыл бұрын

you really should use a charger to charge the battery back up. if it is too dead you could possibly damage the alternator on startup

Not sure you’ll reply in time but would a bad alternator cause truck to just shut off middle of the road going about 55?

With truck running, voltage is 14.1.. if i run over very rough road, the voltage temporarily jumps up and fluctuates between 14.1 and 17.. then after a while, normal. Also happened once when I ran thru need water. Do you think I have loose connections somewhere? I know connections at battery and alternator are good. Where else might I check? 2019 cascadia

depends, newer alternators run a little lower voltage, and higher amperage. anywhere between like 13.7 and 14.1 is very normal
