All electronics are functioning normally, new alternator, new battery, but the battery warning light still stays on.

I think it must be an wiring issue, may be a grounding issue.....

Thoughts anybody!

Cheers

 

is the alternator providing enough juice to the batter?
the light works by providing a resistance and when the alternator pushes more through the other way th elight goes out

so do a double check

 

Try the Little blue wire that goes to the alternator as without it connected the light will stay on.

 

The charge is going to battery, the light comes on as soon as you turn the engine over and stays on until the revs rise above 1200rpm or so.......

But when you measure the voltage going to the battery, it remains the same when the light is on or off......

 

so when measureing the voltage at the abttery it's the same at idle as it is at 1200+rpm?

i would go with the blue wire theory then, it's probably got a break in it somewhere and when you go above a certain rpm the movement of the engine probably makes the connection better and so it goes out

out with the multimetre i'm afraid, it'll be an easy fix but it'll probably be the last wire you check in the bowels of the engine loom

 

Thanks for the advice....... will check the blue wire!
