Nicee👍🏾 thank you!

[@werdlyfe9577]

Thanks for the video...helped me diagnose a faulty alt on my e46

[@RobertWeir]

What year ? How much did the alternator replacement cost ? Could you still drive the car at all even after the red battery light came on ?

[@RobertWeir]

werd thank you

[@werdlyfe9577]

@@RobertWeir no problem. You might want to check the voltage regulator on the alternator as well. From what I researched when I was having issues was that most of the time they are the cause of the alternator issues. I'm a hack and found a cheap alternator so I just swapped out the whole thing. Good luck. I am all to familiar with the frustrations of e46 ownership lol

Good Day On friday i did engen wash with a pressure wahser and decreaser now my alternator is not charging the battery. kindly advise please

[@squelch6573]

13.4 it supposed to be 14.2 !

[@willemgijs3803]

I believe 14.2 is on load. So when going to like 1.5k rpm or 2-3k.

[@prozied3170]

13.5 with instrument cluster, but when you measure battery using multimter you will get 13.00, your issue was not resolved as you supposed to have minimum 14.00

[@ninerdogdude]

my voltage at 9.5 what's wrong??

[@jpadicecoffee9812]

This test works each time for my E46. My good battery fully charged overnight, is about 12.6 volts and a good alternator charges it to about 14.0 to 14.5 range, depends, but it will take a minute for the alternator to get there.

I got a new battery. Car was out for over a year never started after working on many things. So, all is well for a few days driving it around. Started it yesturday backed it out of garage. Later that night was going to spin it somewhere. 100% Dead. Got out a battery charger for vehicles. Eventually got it started again. Turned it off because I wanted to try this video out. It was reading 12.5/12.6 but then when I tried starting it again it would not. Not even any blinking with lights. No dome lights nothing. This is a new battery so I'm lost with what the hell is wrong now suddenly. Any help much appreciated.

[@willemgijs3803]

Start with cables.

[@gruniste]

its not good...its should go above 14 volts

[@Willhgf]

That's what I was thinking

[@jorgeLopez-xn9uy]

I just replaced my alternator and im getting 13.8..before with the old one i was getting 11.8. Im gonna run it and see what happens but my red battery light has gone away.

[@squelch6573]

@@jorgeLopez-xn9uy 13.8 is ok at higher idle ur prolly 14.2 this guy is only 13.4 tho is definitely not ok
