I joined the green/black to the dark green and the white/green to the light green and didn't notice any change to the ammeter which was slightly on the neg side so I swapped them around and still no change on the ammeter.
I tested the alternator with a bulb which lit up nice and bright, so the alternator works ok.
I then let the engine run with the lights on and within 10 mins the lights started to dim and then the engine cut out, the battery was now at 5v so it looks like the battery isn't charging but the alternator seems to be giving good output.
Everything is new i.e. new battery, loom, rectifier, etc.
Has anybody got any ideas, it's doing my head in now
