Hi, Has he converted it from dynamo? Is it actually not charging or is it the light doesn't go out?

Yes it had a dynamo on it, won't charge the battery at all

Hi, there's a couple of ways to do it depending on whether you want to leave or remove the control box. Have a read of this guide to see if it helps. If the alternator is secondhand then did it work before? Did you see it working or was you told it worked? -

What alternator is it? There's only two wires normally, so should be difficult to cock it up completely!

I'm not familiar with the Viva wiring, but as a general rule of thumb the following should apply;

You'll need to remove the dynamo control box. Extend the warning light wire from there onto the terminal marked D+ on the alternator. Also, you'll need to join the two main feed cables together to maintain power supply to the rest of the car.

Then fit a new main charge cable from the terminal B+ to either the starter motor solenoid or straight to the battery positive terminal. Whichever is the shortest/easiest run.
