Daft question time

Have you a pic of yours or know where I could see one

Is that why the bulb holder as 2 connection points ?

 

Yes. It's effectively connected between the alt light output and the battery +12V. It's not connected to ground at all.

 

I'll be back at it Saturday
Can't wait !

 

This is the wire I have on battery light the first blue on the left

 

So starting from scratch

With the ing on but without the engine running

The light should be on

Now at the engine pull the wire off the alternator the light should go off

 

Yes it does that

 

The circuit fine then
Now with it all connected back yup
when you turn it on the light is on start it and the light should go out.
If it doesn't rev it a bit
If it still doesn't with the engine running go to the alternator and put you meter on the big stud and a good earth or the battery neg you should get around 14v

If its around 12v the regulator/alternator is faulty

 

Ok I'll go and try

 

Tried it battery was reading 11.8 when I tested alternator it read 11.7 so there lies my problem
If you have a 12 volt battery and I have had the bus since September why hasn't it dropped much ?
Is it cause I don't use it much ?
The light went out when I bought it could the alternator just break by standing there?

 

11.8v is virtually flat.

 

As zed said, if you're battery's at that voltage, it's flat or (likely) dead. Batteries will self-discharge over time, especially if it's cold.

 

So it's a new alternator then is there a way to test it or is that the way to do it like I did before ?

 

Thanks Matty for all your help ( so far)

 

In your pic, you're missing a black (+12v ignition live) wire on the terminal on the right hand side, next to the lamp with what looks like the blue wire with black stripe. If this is the oil light - that would be (part of) the reason for it not working.
There is a black wire on the LHS terminal - follow that back and see if you can find the one which should be on the RHS.

The brown/white stripey which is flapping about loose possibly comes from the fuel tank sender, and if so should be on the fuel tank gauge. The other terminal of which looks like the red wire has been cut off. This would have gone to one of the terminals on the metal box bolted next to it (voltage stabilizer), and the other terminal on that box would have another black +12v ignition live.
