Cheers' for the welcome. Just wondering if anyone knows why my batterrys not charging and my chg light is on hard. Got an 84 L28 mk and just replaced the alty last year to hitachi with built in reg. done a couple test its reading 12.5v at bat and 12.6 at back of alty. All the earths and fuses are good. Inoxed all plugs and harnesses think there good. Did a drop voltage check and the +bat 2 + alt is reading 1.1 ohms and - 2 - is reading 3.4ohms is that normal and should there be an old as looking black wire with a little metal cylinder on the earth end bridging to a horse shoe connecter on the positive terminal on the back of the alty??..
