very helpful video,thank you,now im just waiting for my brand new alternater to arrive..cheers

A local mechanic was going to charge nearly $500 to change the alternator, plus I would have needed to have the vehicle towed, which would have cost me another $150. I ended up replacing the alternator myself, it cost me less than $135, the truck runs great now. I like saving money by doing things myself, this video has some good advice though the "closed captioning said to get a new alternator at a pot store 🤣😂🤣

I had an issue where i replaced the battery and alternator but it continued to show overcharging. I checked the battery ground etc and it was sturdy. Any thoughts?

[@themachamp6015]

Did you figure it out? Some cars have fusible links instead of fuses. Check for burnt wires at the alternator connection. You would have to replace it with another fusible link since it's a fuse. Over charging will cause the link to burn the wires but has fire retardant heat shrink.

@The Machamp not 100% sure but once i ran the car for a while, alternator went to normal voltage. Guess the vehicle just had to relearn? Customer hasnt returned since so im gonna assume it was just that.

​@@bestbomb17 what did u do cause I'm going through that right now and the mechanic telling me a need a PCM but I really don't feel that's the problem cause I put a new alternator in and it's still overcharging!!!

[@antonio662j]

​@@tluvly66did you ever figure it out

[@jamesortega8681]

when i start car the voltage goes to 16v for about 15 seconds then settles to 14.2v. is that ok or is it a sign alternator is failing

[@user-kw7zb8qw1u]

Take out alternator regulator n add more amps rectifier for higher voltage ⚡ batteries or series instead parallel

[@Markbangsgears]

2 brand new alternators back to back and it over charges what do I do mechanics are telling me it’s normal idk if they are retarted or what 16 volts with battery light is not okay and nothing is giving me good info

[@ahmedalyazid6952]

Guys i found the same problem and i changed everything the alternator the battery but still showing 15.4 v the electricity guys told me it's normel coz u changed bigger battery which is 80 Amber and u should change it to 70 do u think i need to replace new one or there's another problem???

[@LouiesWorld43]

Maybe bad pcm?

[@studymood3941]

Wtf

[@musiclover-uv9ff]

This is how to make a video.

[@stelthcamo357]

I replaced my alternator in my 2006 silverado it still charges over 15.15 volts

[@jacobpaiz8679]

What parts dealer and what brand did you use?

[@stelthcamo357]

@jacobpaiz8679 advance auto I think it's carquest maybe I need To try ac Delco

[@drewrinker2071]

Without a scanner, you hook up a voltmeter to the battery with the car running and see what your voltage is.

[@ScottFree-dl1vy]

Well, that's bullshit. An overcharging alternator isn't always the alternator. There are voltage regulators that are built into the vehicles computer. I just repaired a vehicle that was charging 18 volts. The P.C.M. supplied the grounding that regulated the voltage output for the alternator. Chrysler has done it this way since the 70s.
