update just installed the new cable. Now i have 14,2V on the battery on idle (battery not fully charged yet). it seems to work fine now, going to try it out nearby the following days. extremely greatful for your help!!

Yeah i noticed, that´s why i took it apart and cleaned the connecting areas. It´s been hot there like it´s bad connection im thinking about getting like 1.5m and then mounting it alongside the big cable loom.

Guessing it´s the one that goes to the fuse on picture 2. Next question, are you sure there are no other connectors from there to the alternator? This cable more looks like a 8mm2 rather then 16mm2.

I'll get it, hopefully tomorrow! just gotta be sure now, is it the bottom cable that comes from the alternator output (picture 1) or is it the one that goes to the fuse to the left? (Pic 2)

Cant explain how grateful i am for your help. Im going to take it off now and see if i can find any visible damages.

at 2500 rpm's i got 14,4 at the alternator (the nut and outer casing) meanwhile i got 13,9V at the battery between the poles. Does this mean bad positive cable from alternator to battery?

I also tried measuring V on alternator outer casing and the same nut (positive output) and it's at 13,3V there and sometimes it jumps down tp 12,5v. Isnt this very low right at the alternator?

Looks lite this when i measure those points IMG_3823.MOV

Took of the cap on the nut and measured from this one to battery positive pole and i got - .327VDC with the same load

This is the reading i got from this minus on battery negative pole. headlights on, ac on, radio, blinkers. is this alot?

Bad resolution on last pic

Found this connector for the battery plus, when i measured the V between these spots it was like 0,2-0,3V difference so i took it off and cleaned the connectors, now it´s the same between and now the V is a little better on the battery when engine is running. From 12,7 (off) to 14,13 on idle when i turn off all the electricity but then i tried to turn everything off to see what happens under load. When everything is on (ac, radio, blinkers, headlights etc) the V jumps from 14,13 to 12,78. Is this normal or is the output too low? If so, can it be anything else then alternator?

Since i swapped it and it's probably nothing wrong with the old one i can charge it before trying i thought so too at first but now the battery is swapped and i have the same fault.

Thank you all for putting your time in helping me. It's petrol. Im going to the car tomorrow to try to fix it. Will need to jump start it first but hopefully it keeps running so i can troubleshoot it. Feels like it should be connectors as it comes and goes.

Thank you! Could it be anything other then the alternator or is it just to swap it?
