Battery light denso alternator
Just changed to a small denso alternator 3 wire hook up, battery , ignition lamp and switched live.The battery light is staying on but the battery
is charging at 14.4 volt .The warning light is a bright 6 module,if i reconnect my original alternator the light goes out.
Anyone had the same problem with the warning light.

Due to the way the charge light output is wired up you need to fit a transistor.
It's been covered before, a search should bring it up 
LINKY
transistor solution is detailed in macbeasts post second from last.
And whitestu post confirming he got it working ok HERE

Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

Do you need a transistor?
Havent done this myself yet, but will be when I change engines. I know mine has IG, L and S connections, but whats what I dont know! 
This webpage has some useful info:

And here are all the regulator types with the pins labelled:

Mine's still working fine with the transistor.
It seems unusual, but the alternator outputs a 12v signal to the charge light when stationary, but it is just a signal - there's no current
behind it to light a bulb / high power LED.
The transistor switches the LED on my acewell to earth when it gets the 12v signal so putting on the light.
