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
@@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
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 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.
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.
